  • LibGDX onTouch() method Array and flip method

    - by johnny-b
    How can I add this on my application. i want to use the onTouch() method from the implementation of the InputProcessor to kill the enemies on screen. how do i do that? do i have to do anything to the enemy class? also i am trying to add a Array of enemies and it keeps throwing exceptions or the bullet now is facing LEFT <--- again after I used the flip method in the bullet class. All the code is below so please anyone feel free to have a look thanks. please help Thank you M // This is the bullet class. public class Bullet extends Sprite { public static final float BULLET_HOMING = 6000;

  • How to move child element from one parent to another using jQuery

    - by Kapslok
    I am using the jQuery DataTables plugin. I would like to move the search box (.dataTables_filter) and number of records to display dropdown (.dataTables_length) from their parent element (.dataTables_wrapper) to another div on my page without losing any registered javascript behavior. For instance the search box has a function attached to the 'keyup' event and I want to keep that intact. The DOM looks like this: <body> <div id="parent1"> <div class="dataTables_wrapper" id="table1_wrapper"> <div class="dataTables_length" id="table1_length"> <select size="1" name="table1_length"> <option value="10">10</option> <option value="25">25</option> <option value="50">50</option> <option value="100">100</option> </select> </div> <div class="dataTables_filter" id="table1_filter"> <input type="text" class="search"> </div> <table id="table1"> ... </table> </div> </div> <div id="parent2"> <ul> <li><a href="#">Link A</a></li> <li><a href="#">Link B</a></li> <li><a href="#">Link C</a></li> </ul> </div> </body> This is what I would like the DOM to look like after the move: <body> <div id="parent1"> <div class="dataTables_wrapper" id="table1_wrapper"> <table id="table1"> ... </table> </div> </div> <div id="parent2"> <div class="dataTables_filter" id="table1_filter"> <input type="text" class="search"> </div> <div class="dataTables_length" id="table1_length"> <select size="1" name="table1_length"> <option value="10">10</option> <option value="25">25</option> <option value="50">50</option> <option value="100">100</option> </select> </div> <ul> <li><a href="#">Link A</a></li> <li><a href="#">Link B</a></li> <li><a href="#">Link C</a></li> </ul> </div> </body> I've been looking at the .append(), .appendTo(), .prepend() and .prependTo() functions but haven't had any luck with these in practice. I've also looked at the .parent() and .parents() functions, but can't seem to code a workable solution. I have also considered changing the CSS so that the elements are absolutely positioned - but to be frank the page is setup with fluid elements all over, and I really want these elements to be floated in their new parents. Any help with this is much appreciated.

  • jQuery dynamic field classes not being assigned as desired.

    - by Simon
    Hello, I'm working on a fancy login page with 4 unique states attributed through classes for each field (normal, focus, active-on, active-off). Normal is the default style. Focus is the focus style when nothing is typed. Active-on is the focus style when something has been typed. Active-off is for field that have user text in them, but are not focused right now. Here's a demo to help you understand what I'm doing: http://www.controlstack.com/login My JS is working almost correctly (thanks to some folks on this site), except in 2 cases: If I enter something in the username field, then tab over to the password field, it does not add the ".focus" class to the password field. If I blur out of the username field, then focus back on it, enter a few characters, then delete them, it does not add the ".focus" field. Here's my code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" dir="ltr"> <head> <title>Login</title> <style> input.field {height: 39px; width: 194px; background: url(login-fields.png) no-repeat; overflow: hidden; border: none; outline: none; float: left; margin-right: 7px;} input.field#username {padding: 0 12px;} input.field#username.focus {background-position: 0 -39px;} input.field#username.active-on {background-position: 0 -78px;} input.field#username.active-off {background-position: 0 -117px;} input.field#password {background-position: -218px 0; padding: 0 12px;} input.field#password.focus {background-position: -218px -39px;} input.field#password.active-on {background-position: -218px -78px;} input.field#password.active-off {background-position: -218px -117px;} input.field#go {background-position: -436px 0; width: 88px; margin: 0; cursor: pointer;} </style> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { loginField = $('.field'); firstField = $('.field.first'); firstField.focus(); loginField.focus(function(){ loginVal1 = loginField.val(); if (!loginVal1){ $(this).removeClass('active-off').addClass('focus'); } else { $(this).removeClass('active-off').addClass('active-on'); } }); loginField.live('keydown', function(){ $(this).addClass('active-on').removeClass('active-off'); }).live('keyup', function(){ $(this).toggleClass('active-on', $(this).val() != ''); }) loginField.blur(function(){ loginVal2 = loginField.val(); if (!loginVal2){ $(this).removeClass('focus').removeClass('active-on'); $(this).val(''); } else { $(this).removeClass('focus').removeClass('active-on').addClass('active-off'); } }); }); </script> </head> <body> <h1>Login to your account</h1> <form method="post" action="/"> <fieldset> <input type="text" class="field first focus" id="username" /> <input type="text" class="field" id="password" /> <input type="submit" value="" class="field" id="go" alt="login" title="login" /> </fieldset> </form> </body> </html> Your help is much appreciated!

  • Selecting and inserting text at cursor location in textfield with JS/jQuery

    - by IceCreamYou
    Hello. I have developed a system in PHP which processes #hashtags like on Twitter. Now I'm trying to build a system that will suggest tags as I type. When a user starts writing a tag, a drop-down list should appear beneath the textarea with other tags that begin with the same string. Right now, I have it working where if a user types the hash key (#) the list will show up with the most popular #hashtags. When a tag is clicked, it is inserted at the end of the text in the textarea. I need the tag to be inserted at the cursor location instead. Here's my code; it operates on a textarea with class "facebook_status_text" and a div with class "fbssts_floating_suggestions" that contains an unordered list of links. (Also note that the syntax [#my tag] is used to handle tags with spaces.) maxlength = 140; var dest = $('.facebook_status_text:first'); var fbssts_box = $('.fbssts_floating_suggestions'); var fbssts_box_orig = fbssts_box.html(); dest.keyup(function(fbss_key) { if (fbss_key.which == 51) { fbssts_box.html(fbssts_box_orig); $('.fbssts_floating_suggestions .fbssts_suggestions a').click(function() { var tag = $(this).html(); //This part is not well-optimized. if (tag.match(/W/)) { tag = '[#'+ tag +']'; } else { tag = '#'+ tag; } var orig = dest.val(); orig = orig.substring(0, orig.length - 1); var last = orig.substring(orig.length - 1); if (last == '[') { orig = orig.substring(0, orig.length - 1); } //End of particularly poorly optimized code. dest.val(orig + tag); fbssts_box.hide(); dest.focus(); return false; }); fbssts_box.show(); fbssts_box.css('left', dest.offset().left); fbssts_box.css('top', dest.offset().top + dest.outerHeight() + 1); } else if (fbss_key.which != 16) { fbssts_box.hide(); } }); dest.blur(function() { var t = setTimeout(function() { fbssts_box.hide(); }, 250); }); When the user types, I also need get the 100 characters in the textarea before the cursor, and pass it (presumably via POST) to /fbssts/load/tags. The PHP back-end will process this, figure out what tags to suggest, and print the relevant HTML. Then I need to load that HTML into the .fbssts_floating_suggestions div at the cursor location. Ideally, I'd like to be able to do this: var newSuggestions = load('/fbssts/load/tags', {text: dest.getTextBeforeCursor()}); fbssts_box.html(fbssts_box_orig); $('.fbssts_floating_suggestions .fbssts_suggestions a').click(function() { var tag = $(this).html(); if (tag.match(/W/)) { tag = tag +']'; } dest.insertAtCursor(tag); fbssts_box.hide(); dest.focus(); return false; }); And here's the regex I'm using to identify tags (and @mentions) in the PHP back-end, FWIW. %(\A(#|@)(\w|(\p{L}\p{M}?))+\b)|((?<=\s)(#|@)(\w|(\p{L}\p{M}?))+\b)|(\[(#|@).+?\])%u Right now, my main hold-up is dealing with the cursor location. I've researched for the last two hours, and just ended up more confused. I would prefer a jQuery solution, but beggars can't be choosers. Thanks!

  • html button elemenents and onserverclick attribute in asp.net

    - by Adrian Adkison
    I have been experiencing some very strange behavior using html buttons with the onserverclick attribute. What I am trying to do is use jQuery to designate the default button on the page. By default button I mean the button that is "clicked" when a user hits enter. In testing, I would hit enter while in an input field and sometimes the intended "default" button was clicked and the server side method defined in the corresponding onserverclick attribute was hit. Other times a post back was made without hitting the server method. In order to isolate the issue I created a minimal test case and found some very interesting results. client side: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> <script type="text/javascript" src="/scripts/jquery-1.4.min.js"></script> </head> <body> <form id="form1" runat="server"> <asp:Label ID="_response" runat="server"></asp:Label> <input id="input1" type="text" /> <input id="input2" type="text" /> <button id="first" type="button" class="defaultBtn" runat="server" onserverclick="ServerMethod1">test1</button> <button id="second" type="button" runat="server" onserverclick="ServerMethod2">test2</button> </form> <script type="text/javascript"> jQuery('form input').keyup( function(e) { if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { $('button.defaultBtn').click(); return true; } } ); </script> </body> </html> server side: public partial class admin_spikes_ButtonSubmitTest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void ServerMethod1(object sender, EventArgs e) { _response.Text = "server method1 was hit"; } protected void ServerMethod2(object sender, EventArgs e) { _response.Text = "server method2 was hit"; } } What I found was that everything worked as expected with this code except when I removed one of the input elements. In Firefox 3.6 and IE 8 when only one input exists on the page, hitting enter does not trigger the onserverclick, it makes a post back without even being jQuery "clicked" or actually "clicked". You can test this by starting with two inputs and clicking "test2". This will output "server method2 was hit". Then just hit enter and the output will be "server method1 was hit. Now take away an input and run the same test. Click "test2" see the results, then hit enter and you will see that nothing will change because the "test1" method was never hit. Does anyone know what is going on? Thanks p.s. Chrome worked as expected

  • BB Code Parser (in formatting phase) with jQuery jammed due to messed up loops most likely

    - by Oskar
    Greetings everyone, I'm making a BB Code Parser but I'm stuck on the JavaScript front. I'm using jQuery and the caret library for noting selections in a text field. When someone selects a piece of text a div with formatting options will appear. I have two issues. Issue 1. How can I make this work for multiple textfields? I'm drawing a blank as it currently will detect the textfield correctly until it enters the $("#BBtoolBox a").mousedown(function() { } loop. After entering it will start listing one field after another in a random pattern in my eyes. !!! MAIN Issue 2. I'm guessing this is the main reason for issue 1 as well. When I press a formatting option it will work on the first action but not the ones afterwards. It keeps duplicating the variable parsed. (if I only keep to one field it will never print in the second) Issue 3 If you find anything especially ugly in the code, please tell me how to improve myself. I appriciate all help I can get. Thanks in advance $(document).ready(function() { BBCP(); }); function BBCP(el) { if(!el) { el = "textarea"; } // Stores the cursor position of selection start $(el).mousedown(function(e) { coordX = e.pageX; coordY = e.pageY; // Event of selection finish by using keyboard }).keyup(function() { BBtoolBox(this, coordX, coordY); // Event of selection finish by using mouse }).mouseup(function() { BBtoolBox(this, coordX, coordY); // Event of field unfocus }).blur(function() { $("#BBtoolBox").hide(); }); } function BBtoolBox(el, coordX, coordY) { // Variable containing the selected text by Caret selection = $(el).caret().text; // Ignore the request if no text is selected if(selection.length == 0) { $("#BBtoolBox").hide(); return; } // Print the toolbox if(!document.getElementById("BBtoolBox")) { $(el).before("<div id=\"BBtoolBox\" style=\"left: "+ ( coordX + 5 ) +"px; top: "+ ( coordY - 30 ) +"px;\"></div>"); // List of actions $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_bold.png\" alt=\"B\" title=\"Bold\" /></a>"); $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_italic.png\" alt=\"I\" title=\"Italic\" /></a>"); } else { $("#BBtoolBox").css({'left': (coordX + 3) +'px', 'top': (coordY - 30) +'px'}).show(); } // Parse the text according to the action requsted $("#BBtoolBox a").mousedown(function() { switch($(this).children(":first").attr("alt")) { case "B": // bold parsed = "[b]"+ selection +"[/b]"; break; case "I": // italic parsed = "[i]"+ selection +"[/i]"; break; } // Changes the field value by replacing the selection with the variable parsed $(el).val($(el).caret().replace(parsed)); $("#BBtoolBox").hide(); return false; }); }

  • Why is parsing a jSON response to a jQUERY ajax request not working

    - by Ankur
    I know there are several similar questions on SO, I have used some of them to get this far. I am trying to list a set of urls that match my input values. I have a servlet which takes some input e.g. "aus" in the example below and returns some output using out.print() e.g. the two urls I have shown below. EXAMPLE Input: "aus" Output: [{"url":"http://dbpedia.org/resource/Stifel_Nicolaus"},{"url":"http://sempedia.org/ontology/object/Australia"}] Which is exactly what I want. I have seen that firebug doesn't seem to have anything in the response section despite having called out.print(jsonString); and it seems that out.print(jsonString); is working as expected which suggests that the variable 'jsonString' contains the expected values. However I am not exactly sure what is wrong. -------- The jQuery --------- $(document).ready(function() { $("#input").keyup(function() { var input = $("#input").val(); //$("#output").html(input); ajaxCall(input); }); }); function ajaxCall(input) { // alert(input); $.ajax({ url: "InstantSearchServlet", data: "property="+input, beforeSend: function(x) { if(x && x.overrideMimeType) { x.overrideMimeType("application/j-son;charset=UTF-8"); } }, dataType: "json", success: function(data) { for (var i = 0, len = datalength; i < len; ++i) { var urlData = data[i]; $("#output").html(urlData.url); } } }); } ------ The Servlet that calls the DAO class - and returns the results ------- public class InstantSearchServlet extends HttpServlet{ private static final long serialVersionUID = 1L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { System.out.println("You called?"); response.setContentType("application/json"); PrintWriter out = response.getWriter(); InstantSearch is = new InstantSearch(); String input = (String)request.getParameter("property"); System.out.println(input); try { ArrayList<String> urllist; urllist = is.getUrls(input); String jsonString = convertToJSON(urllist); out.print(jsonString); System.out.println(jsonString); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } private String convertToJSON(ArrayList<String> urllist) { Iterator<String> itr = urllist.iterator(); JSONArray jArray = new JSONArray(); int i = 0; while (itr.hasNext()) { i++; JSONObject json = new JSONObject(); String url = itr.next(); try { json.put("url",url); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } jArray.put(json); } String results = jArray.toString(); return results; } }

  • Dual AJAX Requests at different times

    - by Nik
    Alright, I'm trying to make an AJAX Chat system that polls the chat database every 400ms. That part is working, the part of which isn't is the Active User List. When I try to combine the two requests, the first two requests are made, then the whole thing snowballs and the usually timed (12 second) Active User List request starts updating every 1ms and the first request NEVER happens again. Displayed is the entire AJAX code for both requests: var waittime=400;chatmsg=document.getElementById("chatmsg"); room = document.getElementById("roomid").value; chatmsg.focus() document.getElementById("chatwindow").innerHTML = "loading..."; document.getElementById("userwindow").innerHTML = "Loading User List..."; var xmlhttp = false; var xmlhttp2 = false; var xmlhttp3 = false; function ajax_read(url) { if(window.XMLHttpRequest){ xmlhttp=new XMLHttpRequest(); if(xmlhttp.overrideMimeType){ xmlhttp.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState==4) { document.getElementById("chatwindow").innerHTML = xmlhttp.responseText; setTimeout("ajax_read('methods.php?method=r&room=" + room +"')", waittime); } } xmlhttp.open('GET',url,true); xmlhttp.send(null); } function user_read(url) { if(window.XMLHttpRequest){ xmlhttp3=new XMLHttpRequest(); if(xmlhttp3.overrideMimeType){ xmlhttp3.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp3=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp3=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp3) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp3.onreadystatechange = function() { if (xmlhttp3.readyState==4) { document.getElementById("userwindow").innerHTML = xmlhttp3.responseText; setTimeout("ajax_read('methods.php?method=u&room=" + room +"')", 12000); } } xmlhttp3.open('GET',url,true); xmlhttp3.send(null); } function ajax_write(url){ if(window.XMLHttpRequest){ xmlhttp2=new XMLHttpRequest(); if(xmlhttp2.overrideMimeType){ xmlhttp2.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp2=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp2=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp2) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp2.open('GET',url,true); xmlhttp2.send(null); } function submit_msg(){ nick = document.getElementById("chatnick").value; msg = document.getElementById("chatmsg").value; document.getElementById("chatmsg").value = ""; ajax_write("methods.php?method=w&m=" + msg + "&n=" + nick + "&room=" + room + ""); } function keyup(arg1) { if (arg1 == 13) submit_msg(); } var intUpdate = setTimeout("ajax_read('methods.php')", waittime); var intUpdate = setTimeout("user_read('methods.php')", waittime);

  • Tablesorter - filter inside input fields and values

    - by Zeracoke
    I have a small quest to accomplish, and I reached a point when nothing works... So the problem is. I have a paged table with a lot of input fields inside the rows with values, and I would like to search inside these values. Let me Show this, I hope that somebody will got the idea what I should do... <script type="text/javascript"> // add parser through the tablesorter addParser method $.tablesorter.addParser({ id: 'inputs', is: function(s) { return false; }, format: function(s, table, cell, cellIndex) { var $c = $(cell); // return 1 for true, 2 for false, so true sorts before false if (!$c.hasClass('updateInput')) { $c .addClass('updateInput') .bind('keyup', function() { $(table).trigger('updateCell', [cell, false]); // false to prevent resort }); } return $c.find('input').val(); }, type: 'text' }); $(function() { $('table').tablesorter({ widgets: ['zebra', 'stickyHeaders', 'resizable', 'filter'], widgetOptions: { stickyHeaders : '', // number or jquery selector targeting the position:fixed element stickyHeaders_offset : 110, // added to table ID, if it exists stickyHeaders_cloneId : '-sticky', // trigger "resize" event on headers stickyHeaders_addResizeEvent : true, // if false and a caption exist, it won't be included in the sticky header stickyHeaders_includeCaption : true, // The zIndex of the stickyHeaders, allows the user to adjust this to their needs stickyHeaders_zIndex : 2, // jQuery selector or object to attach sticky header to stickyHeaders_attachTo : null, // scroll table top into view after filtering stickyHeaders_filteredToTop: true, resizable: true, filter_onlyAvail : 'filter-onlyAvail', filter_childRows : true, filter_startsWith : true, filter_useParsedData : true, filter_defaultAttrib : 'data-value' }, headers: { 1: {sorter: 'inputs', width: '50px'}, 2: {sorter: 'inputs'}, 3: {sorter: 'inputs'}, 4: {sorter: 'inputs'}, 5: {sorter: 'inputs'}, 6: {sorter: 'inputs'}, 7: {sorter: 'inputs', width: '100px'}, 8: {sorter: 'inputs', width: '140px'}, 9: {sorter: 'inputs'}, 10: {sorter: 'inputs'}, 11: {sorter: 'inputs'}, } }); $('table').tablesorterPager({container: $(".pager"), positionFixed: false, size: 50, pageDisplay : $(".pagedisplay"), pageSize : $(".pagesize"), }); $("#table1").tablesorter(options); /* make second table scroll within its wrapper */ options.widgetOptions.stickyHeaders_attachTo = '.wrapper'; // or $('.wrapper') $("#table2").tablesorter(options); }); </script> The structure of the tables: <tr class="odd" style="display: table-row;"> <form action="/self.php" method="POST"> </form><input type="hidden" name="f" value="data"> <td><input type="hidden" name="mod_id" value="741">741</td> <td class="updateInput"><input type="text" name="name" value="Test User Name"></td> <td class="updateInput"><input type="text" name="address" value="2548451 Random address"></td> <td class="updateInput"><input type="email" name="email" value=""></td> <td class="updateInput"><input type="text" name="entitlement" value="none"></td> <td class="updateInput"><input type="text" name="card_number" value="6846416548644352"></td> <td class="updateInput"><input type="checkbox" name="verify" value="1" checked=""></td> <td class="updateInput"><input type="checkbox" name="card_sended" value="1" checked=""></td> <td class="updateInput"><input type="text" name="create_date" value="2014-02-12 21:09:16"></td> <td class="updateInput"><a href="self.php?f=data&amp;del=741">X</a></td> <td class="updateInput"><input type="submit" value="SAVE"></td><td class="updateInput"></td></tr> So the thing is I don't know how to configure the filter to search these values... I already added some options, but none of them are working... Any help would be great!

  • PHP Form - Empty input enter this text - Validation

    No doubt very simple question for someone with php knowledge. I have a form with a datepicker, all is fine when a user has selected a date the email is send with: Date: 2012 04 10 But i would like if the user has skipped this and left blank (as i have not made this required) to send as: Date: Not Entered (<-- Or something) Instead at the minute of course it reads: Date: Form input <input type="text" class="form-control" id="datepicker" name="datepicker" size="50" value="Date Of Wedding" /> This is the validator $(document).ready(function(){ //validation contact form $('#submit').click(function(event){ event.preventDefault(); var fname = $('#name').val(); var validInput = new RegExp(/^[a-zA-Z0-9\s]+$/); var email = $('#email').val(); var validEmail = new RegExp(/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/); var message = $('#message').val(); if(fname==''){ showError('<div class="alert alert-danger">Please enter your name.</div>', $('#name')); $('#name').addClass('required'); return;} if(!validInput.test(fname)){ showError('<div class="alert alert-danger">Please enter a valid name.</div>', $('#name')); $('#name').addClass('required'); return;} if(email==''){ showError('<div class="alert alert-danger">Please enter an email address.</div>', $('#email')); $('#email').addClass('required'); return;} if(!validEmail.test(email)){ showError('<div class="alert alert-danger">Please enter a valid email.</div>', $('#email')); $('#email').addClass('required'); return;} if(message==''){ showError('<div class="alert alert-danger">Please enter a message.</div>', $('#message')); $('#message').addClass('required'); return;} // setup some local variables var request; var form = $(this).closest('form'); // serialize the data in the form var serializedData = form.serialize(); // fire off the request to /contact.php request = $.ajax({ url: "contact.php", type: "post", data: serializedData }); // callback handler that will be called on success request.done(function (response, textStatus, jqXHR){ $('.contactWrap').show( 'slow' ).fadeIn("slow").html(' <div class="alert alert-success centered"><h3>Thank you!

  • Encoding GBK2312 Condundrum

    - by user792271
    I am an amateur coder and I have a small problem. My goal is to have one text input with two buttons. The first button uses a bit of Javascript called SundayMorning to translate the text (to Chinese) The second button submits the text to a URL. The URl requires that Chinese text be encoded it in GBK2312 character set. I have duct taped together various found code to the result I have now. Due to the finicky behavior of the SundayMorning Javascript, my solution is to have two input boxes, the second of which I will hide. Right now, this doesn't work: I am unable to encode the Chinese in GBK2312, no matter what I try. BONUS CONUNDRUM: The second box copies my input letter by letter as I type, but does not copy the Chinese translation that the Javascript returns. Sorry for my janky amateur code. I defer to those more clever, if you have any kind suggestions. <head> <meta http-equiv="Content-Type" content="text/html; charset=GB2312" /> <script type='text/javascript' Src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js'> </script> ///THIS JS TRANSLATES THE TEXT INLINE <script type="text/javascript" src="jquery.sundaymorning.js"> </script> <script type="text/javascript"> $(function() { $('#example3').sundayMorningReset(); $('#example3 input[type=image]').click(function(evt) { $.sundayMorning( $('#example3 input[type=text]').val(),{source:'en', destination:'ZH', menuLeft:evt.pageX, menuTop:evt.pageY},function(response) {$('#example3 input[type=text]').val(response.translation);});});}); </script> /// ///THIS PUTS THE CONTENT OF THE TRANSLATION BOX INTO THE SUBMISSION BOX <script type="text/javascript"> $(document).ready(function(){ var $url = $("#url"); $("#track").keyup(function() { $url.val(this.value);}); $("#track").blur(function() { $url.val(this.value);});}); </script> ///THIS PUTS THE CONTENT OF THE SUBMISSION INSIDE A URL <SCRIPT type="text/javascript"> function goToPage(url) { var initial = "http://example.com/"; var extension = ".html"; document.something.action=initial+url+extension; } </SCRIPT> </head> <body> <div id="featured"> <div id="example3"> <input type="text" name="track" id="track" value="" class="box"onkeydown="javascript:if (event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('mama').click();}};"/> <input type="image" src="http://taobaofieldguide.com/images/orange-translate-button.png" id="searchsubmit" value="Translate" class="btn" /> </div> <FORM name="something" method="post" onsubmit="goToPage(this.url.value);"> <input type="text" id="url";> <INPUT type="submit" id="mama" value="GO" > </FORM> </div> </body>

  • I am making a maze type of game using javascript and HTML and need some questions answered [on hold]

    - by Timothy Bilodeau
    First off, i am a noob to JavaScript but am willing to learn. :) I found a simple JavaScript moment engine created by another member on this site. Using that i made it so my character can walk around within a rectangle/square shaped room. I want to make it so the character can walk through a "doorway" within a wall to the next room. Either that or make it so if the character moves over a certain image within the room it will take the player to another webpage in which the character "spawns" into the room and so on and so fourth. Here is a link to what i have made so far as to get an idea. http://bit.ly/1fSMesA Any help would be much appreciated. Here is the javascript code for the character movement and boundaries. <script type='text/javascript'> // movement vars var xpos = 100; var ypos = 100; var xspeed = 1; var yspeed = 0; var maxSpeed = 5; // boundary var minx = 37; var miny = 41; var maxx = 187; // 10 pixels for character's width var maxy = 178; // 10 pixels for character's width // controller vars var upPressed = 0; var downPressed = 0; var leftPressed = 0; var rightPressed = 0; function slowDownX() { if (xspeed > 0) xspeed = xspeed - 1; if (xspeed < 0) xspeed = xspeed + 1; } function slowDownY() { if (yspeed > 0) yspeed = yspeed - 1; if (yspeed < 0) yspeed = yspeed + 1; } function gameLoop() { // change position based on speed xpos = Math.min(Math.max(xpos + xspeed,minx),maxx); ypos = Math.min(Math.max(ypos + yspeed,miny),maxy); // or, without boundaries: // xpos = xpos + xspeed; // ypos = ypos + yspeed; // change actual position document.getElementById('character').style.left = xpos; document.getElementById('character').style.top = ypos; // change speed based on keyboard events if (upPressed == 1) yspeed = Math.max(yspeed - 1,-1*maxSpeed); if (downPressed == 1) yspeed = Math.min(yspeed + 1,1*maxSpeed) if (rightPressed == 1) xspeed = Math.min(xspeed + 1,1*maxSpeed); if (leftPressed == 1) xspeed = Math.max(xspeed - 1,-1*maxSpeed); // deceleration if (upPressed == 0 && downPressed == 0) slowDownY(); if (leftPressed == 0 && rightPressed == 0) slowDownX(); // loop setTimeout("gameLoop()",10); } function keyDown(e) { var code = e.keyCode ? e.keyCode : e.which; if (code == 38) upPressed = 1; if (code == 40) downPressed = 1; if (code == 37) leftPressed = 1; if (code == 39) rightPressed = 1; } function keyUp(e) { var code = e.keyCode ? e.keyCode : e.which; if (code == 38) upPressed = 0; if (code == 40) downPressed = 0; if (code == 37) leftPressed = 0; if (code == 39) rightPressed = 0; } </script> here is the HTML code to follow <!-- The Level --> <img src="room1.png" /> <!-- The Character --> <img id='character' src='../texture packs/characters/snazgel.png' style='position:absolute;left:100;top:100;height:40;width:26;'/>

  • BING Search using ASP.NET and jQuery Ajax

    - by hajan
    The BING API provides extremely simple way to make search queries using BING. It provides nice way to get the search results as XML or JSON. In this blog post I will show one simple example on how to query BING and get the results as JSON in an ASP.NET website with help of jQuery’s getJSON ajax method. Basically we submit an HTTP GET request with the AppID which you can get in the BING Developer Center. To create new AppID, click here. Once you fill the form, submit it and you will get your AppID. Now, lets make this work in several steps. 1. Open VS.NET or Visual Web Developer.NET, create new sample project (or use existing one) and create new ASPX Web Form with name of your choice. 2. Add the following ASPX in your page body <body>     <form id="form1" runat="server">     <asp:TextBox ID="txtSearch" runat="server" /> <asp:Button ID="btnSearch" runat="server" Text="BING Search" />     <div id="result">          </div>     </form> </body> We have text box for search, button for firing the search event and div where we will place the results. 3. Next, I have created simple CSS style for the search result: <style type="text/css">             .item { width:600px; padding-top:10px; }             .title { background-color:#4196CE; color:White; font-size:18px;              font-family:Calibri, Verdana, Tahoma, Sans-Serif; padding:2px 2px 2px 2px; }     .title a { text-decoration:none; color:white}     .date { font-style:italic; font-size:10px; font-family:Verdana, Arial, Sans-Serif;}             .description { font-family:Verdana, Arial, Sans-Serif; padding:2px 2px 2px 2px; font-size:12px; }     .url { font-size: 10px; font-style:italic; font-weight:bold; color:Gray;}     .url a { text-decoration:none; color:gray;}     #txtSearch { width:450px; border:2px solid #4196CE; } </style> 4. The needed jQuery Scripts (v1.4.4 core jQuery and jQuery template plugin) <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.4.min.js" type="text/javascript"></script> <script src="http://ajax.aspnetcdn.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js" type="text/javascript"></script> Note: I use jQuery Templates plugin in order to avoid foreach loop in the jQuery callback function. JQuery Templates also simplifies the code and allows us to create nice template for the end result. You can read more about jQuery Templates here. 5. Now, lets create another script tag where we will write our BING search script <script language="javascript" type="text/javascript">     $(document).ready(function () {         var bingAPIKey = "<Your-BING-AppID-KEY-HERE>";                  //the rest of the script goes here              }); </script> 6. Before we do any searching, we need to take a look at the search URL that we will call from our Ajax function BING Search URL : http://api.search.live.net/json.aspx?JsonType=callback&JsonCallback=?&AppId={appId}&query={query}&sources={sourceType} The URL in our example is as follows: http://api.search.live.net/json.aspx?JsonType=callback&JsonCallback=?&Appid=" + bingAPIKey + "&query=" + keyWords + "&sources=web Lets split it up with brief explanation on each part of the URL http://api.search.live.net/json.aspx – is the main part of the URL which is used to call when we need to retrieve json result set. JsonType=callback&JsonCallback=? – using JsonType, we can control the format of the response. For more info about this, refer here. Appid=” + bingAPIKey +” – the AppID we’ve got from the BING website, explained previously query=” + keyWords + “ – the search query keywords sources=web – the type of source. Possible source types can be found here. 7. Before we continue with writing the last part of the script, lets see what search result BING will send us back: {"SearchResponse":     {         "Version":"2.2",         "Query":             {                 "SearchTerms":"hajan selmani aspnet weblog"             },         "Web":             {                 "Total":16,                 "Offset":0,                 "Results":[                     {                         "Title":"Hajan's Blog",                         "Description":"microsoft asp.net development blog ... Create nice animation on your ASP.NET Menu control using jQuery by hajan",                         "Url":"http:\/\/weblogs.asp.net\/hajan\/",                         "CacheUrl":"http:\/\/cc.bingj.com\/cache.aspx?q=hajan+selmani+aspnet+weblog&d=4760941354158132&w=c9535fb0,d1d66baa",                         "DisplayUrl":"weblogs.asp.net\/hajan",                         "DateTime":"2011-03-03T18:24:00Z"                     },                     {                         "Title":"codeasp.net",                         "Description":"... social community for ASP.NET bloggers - we are one of                                         the largest ASP.NET blog ... 2\/5\/2011 1:41:00 AM by Hajan Selmani - Comments ...",                         "Url":"http:\/\/codeasp.net\/blogs\/hajan",                         "CacheUrl":"http:\/\/cc.bingj.com\/cache.aspx?q=hajan+selmani+aspnet+weblog&d=4826710187311653&w=5b41c930,676a37f8",                         "DisplayUrl":"codeasp.net\/blogs\/hajan",                         "DateTime":"2011-03-03T07:40:00Z"                     }                     ...                         ]             }     } }  To get to the result of the search response, the path is: SearchResponse.Web.Results, where we have array of objects returned back from BING. 8. The final part of the code that performs the search is $("#<%= btnSearch.ClientID %>").click(function (event) {     event.preventDefault();     var keyWords = $("#<%= txtSearch.ClientID %>").val();     var encodedKeyWords = encodeURIComponent(keyWords);     //alert(keyWords);     var url = "http://api.search.live.net/json.aspx?JsonType=callback&JsonCallback=?&Appid="+ bingAPIKey              + "&query=" + encodedKeyWords              + "&sources=web";     $.getJSON(url, function (data) {         $("#result").html("");         $("#bingSearchTemplate").tmpl(data.SearchResponse.Web.Results).appendTo("#result");     }); }); The search happens once we click the Search Button with id btnSearch. We get the keywords from the Text Box with id txtSearch and then we use encodeURIComponent. The encodeURIComponent is used to encode the special characters such as: , / ? : @ & = + $ #, which might be part of the search query string. Then we construct the URL and call it using HTTP GET. The callback function returns the data, where we first clear the html inside div with id result and after that we render the data.SearchResponse.Web.Results array of objects using template with id bingSearchTemplate and append the result into div with id result. 9. The bingSearchTemplate Template <script id="bingSearchTemplate" type="text/html">     <div class="item">         <div class="title"><a href="${Url}" target="_blank">${Title}</a></div>         <div class="date">${DateTime}</div>         <div class="searchresult">             <div class="description">             ${Description}             </div>             <div class="url">                 <a href="${Url}" target="_blank">${Url}</a>             </div>         </div>     </div> </script> If you paid attention on the search result structure that BING creates for us, you have seen properties like Url, Title, Description, DateTime etc. In the above defined template, you see the same wrapped into template tags. Some are combined to create hyperlinked URLs. 10. THE END RESULT   As you see, it’s quite simple to use BING API and make search queries with ASP.NET and jQuery. In addition, if you want to make instant search, replace this line: $(“#<%= btnSearch.ClientID %>”).click(function(event) {        event.preventDefault(); with $(“#<%= txtSearch.ClientID %>”).keyup(function() { This will trigger search on each key up in your keyboard, so if you use this approach, you won’t event need a search button. If it’s your first time working with BING API, it’s very recommended to read the following API Basics PDF document. Hope this was helpful blog post for you.

  • Should one replace the usage addJSONData of jqGrid to the usage of setGridParam(), and trigger('relo

    - by Oleg
    Hi everybody who use jqGrid! I am a new on stackoverflow.com and it seems to me that a lot of peoples who use stackoverflow.com are not only the persons who have a problem which must be quickly solved. A lot of people read stackoverflow.com to look at well-known things from the other side. Sometime perhaps the reason is a self-training (to stay in the good form) during solving of problems other people. For all these gays, who not want only to solve his problem is my question. I wrote recently an answer to the question "jqGrid display default “loading” message when updating a table / on custom update". During writing of the answer I thought: why he uses addJSONData() function for refresh of data in the grid instead of changing URL with respect of setGridParam() and refreshing jqGrid data with respect of trigger('reloadGrid')? At the beginning I wanted to recommend using of 'reloadGrid', but after thinking about this I understood, that I am not quite sure what the best way is. At least I can't explain in two sentences why I prefer the second way. So I decide that it could be an interesting subject of a discussion. So to be exactly: We have a typical situation. We have a web page with at least one jqGrid and some other controls like combo-boxes (selects), checkboxes etc. which give user possibilities to change scope on information displayed in a jqGrid. Typically we define some event handler like jQuery("#selector").change(myRefresh).keyup(myKeyRefresh) and we need reload the jqGrid contain based on users choose. After reading and analyzing of the information from additional users input we can refresh jqGrid contain in at least two ways: Make call of $.ajax() manual and then inside of success or complete handle of $.ajax call jQuery.parseJSON() (or eval) and then call addJSONData function of jqGrid. I found a lot of examples on stackoverflow.com who use addJSONData. Update url of jqGrid based on users input, reset current page number to 1 and optionally change the caption of the grid. All these can be done with respect of setGridParam(), and optionally setCaption() jqGrid methods. At the end one call trigger('reloadGrid') method of the grid. To construct the url, by the way I use mostly jQuery.param function to be sure, that I all url parameters packed correctly with respect of encodeURIComponent. I want that we discuss advantages and disadvantages of both ways. I use currently the second way, so I start with advantages of this one. One can say me: I call existing Web Service, convert received data to the jqGrid format and call addJSONData. This is the reason why I use addJSONData method! OK, I choose another way. jqGrid can make a call of the Web Service directly and fill results inside of grid. There are a lot of jqGrid options, which allow you to customize this process. First of all, one can delete or rename any standard parameter sent to server with respect of prmNames option of jqGrid or add any more additional parameters with respect of postData option (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:options). One can modify all constructed parameters immediately before jqGrid makes corresponding $.ajax request by defining of serializeGridData() function (one more option of jqGrid). More than that, one can change every $.ajax parameter by setting ajaxGridOptions option of jqGrid. I use ajaxGridOptions: {contentType: "application/json"} for example as a general setting of $.jgrid.defaults. The ajaxGridOptions option is very powerful. With respect of ajaxGridOptions option one can redefine any parameter of $.ajax request sending by jqGrid, like error, complete and beforeSend events. I see potentially interesting to define dataFilter event to be able makes any modification of the row data responded from the server. One more argument for using of trigger('reloadGrid') way is blocking of jqGrid during ajax request processing. Mostly I use parameter loadui: 'block' to block jqGrid during JSON request sending to server. With respect of jQuery blockUI plugin http://malsup.com/jquery/block/ one can block more parts of web page as the grid only. To do this one can call jQuery('#main').block({ message: '<h1>Die Daten werden vom Server geladen...</h1>' }); before calling of trigger('reloadGrid') method and jQuery('#main').unblock() inside of loadComplete and loadError functions. The loadui option could be set to 'disable' in this case. So I don’t see why the function addJSONData() should be used. Can somebody who use addJSONData() function explain me advantages of its usage? Should one replace the usage addJSONData of jqGrid to the usage of setGridParam(), and trigger('reloadGrid')? I am opened to the discussion.

  • lwjgl isKeyDown canceling out other keys

    - by AKrush95
    While trying to create a simple game where a square is manipulated via the keyboard keys, I have come across a small, rather irritating problem. I would like it to work so that when the opposite directional key is pressed, the character will stop; the character may move the other two directions while stopped in this situation. This works perfectly with LEFT and RIGHT held down; the player may move UP or DOWN. If UP and DOWN are held down, however, the player will not move, nor will Java recognize that the LEFT or RIGHT keys were pressed. import java.util.ArrayList; import java.util.Random; import org.lwjgl.*; import org.lwjgl.input.Keyboard; import org.lwjgl.opengl.*; import static org.lwjgl.opengl.GL11.*; public class Main { private Man p; private ArrayList<Integer> keysDown, keysUp; public Main() { try { Display.setDisplayMode(new DisplayMode(640, 480)); Display.setTitle("LWJGLHelloWorld"); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); } p = new Man(0, 0); keysDown = new ArrayList<>(); keysUp = new ArrayList<>(); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0, 640, 480, 0, 1, -1); glMatrixMode(GL_MODELVIEW); while (!Display.isCloseRequested()) { glClear(GL_COLOR_BUFFER_BIT); checkKeys(); p.draw(); Display.update(); Display.sync(60); } Display.destroy(); } public void checkKeys() { ArrayList<Integer> keys = new ArrayList<>(); keys.add(Keyboard.KEY_A); keys.add(Keyboard.KEY_D); keys.add(Keyboard.KEY_W); keys.add(Keyboard.KEY_S); for (int key : keys) { if (Keyboard.isKeyDown(key)) keysDown.add(key); else keysUp.add(key); } keysDown.removeAll(keysUp); keysUp = new ArrayList<>(); int speed = 4; int dx = 0; int dy = 0; if (keysDown.contains(keys.get(2))) { System.out.println("keyUP"); dy -= speed; } if (keysDown.contains(keys.get(3))) { System.out.println("keyDOWN"); dy += speed; } if (keysDown.contains(keys.get(0))) { System.out.println("keyLEFT"); dx -= speed; } if (keysDown.contains(keys.get(1))) { System.out.println("keyRIGHT"); dx += speed; } //if (keysDown.contains(keys.get(0)) && keysDown.contains(keys.get(1))) dx = 0; //if (keysDown.contains(keys.get(2)) && keysDown.contains(keys.get(3))) dy = 0; p.update(dx, dy); } public static void main(String[] args) { new Main(); } class Man { public int x, y, w, h; public float cR, cG, cB; public Man(int x, int y) { this.x = x; this.y = y; w = 50; h = 50; Random rand = new Random(); cR = rand.nextFloat(); cG = rand.nextFloat(); cB = rand.nextFloat(); } public void draw() { glColor3f(cR, cG, cB); glRecti(x, y, x+w, y+h); } public void update(int dx, int dy) { x += dx; y += dy; } } } That is the code that I am working with. In addition, I am unsure how to compile an executable jar that is using the lwjgl library in addition to slick-util.
