  • How to capture a click on a link on a temporary layer that is hidden when the focus changes

    - by hstoerr
    We have a layer that appears when a certain text input has the focus and that should dissappear when the input loses the focus. I tried to do it like this: <input type="text" onblur="document.getElementById('hideme').style.display='none'" /> <div id="hideme">Textextext <a href="http://disney.com/">disney</a> text</div> My problem is: when the user clicks on the link link, the browser does not follow this link. It seems the layer disappears before the browser checks where the click goes. What can I do here? One idea would be to watch whether the mouse enters the hideme div and not to close it when the mouse cursor is in there, but this seems way to complicated. Do you have a better idea? By the way: you can try it out very easy by pasting this into the Tryit Editor of w3schools. :-)

  • javascript date.utc problem

    - by Dave
    I'm trying to compare 2 dates using javascript. 1 at the end of the month and 1 at the beginning. I need to compare these 2 dates in seconds so I'm using the Date.UTC javascript function. Here's the code: var d = Date.UTC(2010,5,31,23,59,59); document.write(d); var d2 = Date.UTC(2010,6,1,12,20,11); document.write(d2); The output for is: 1278028799000 1277986811000 This is telling me that 1/6/2010 is less than 5/31/2010 in milliseconds. How is that possible? What am I doing wrong? Thanks for your help.

  • JavaScript and ASP.NET - Cookies with Key / Value Pairs

    - by user208662
    Hello, This question mixes client-side scripting with server-side parsing. In some cases, I'm writing a cookie to the user's browser using the document.cookie property. In other cases, I'm writing the same cookie to the user's browser through the ASP.NET Response object. When I'm writing the HttpCookie on the server-side, I am using the Values collection (http://msdn.microsoft.com/en-US/library/system.web.httpcookie.values%28v=VS.80%29.aspx) to store key/value pairs in the cookie. I would also like to be able to write key-value pairs to the cookie through JavaScript. How do I create cookies with Key/Value pairs via JavaScript that ASP.NET can parse? Thank you!

  • Output something other than True or False

    - by David
    Newb to JS. Trying to determain how to to output something other than Question 1 is True and False. If I understand this correctly, the output is the expression of the flag True or False. Trying to change to say Correct and Incorrect. Also trying to express a percentage of correct instead of the for example: Your total score is 10/100 $(function(){ var jQuiz = { answers: { q1: 'd', q2: 'd', }, questionLenght: 2, checkAnswers: function() { var arr = this.answers; var ans = this.userAnswers; var resultArr = [] for (var p in ans) { var x = parseInt(p) + 1; var key = 'q' + x; var flag = false; if (ans[p] == 'q' + x + '-' + arr[key]) { flag = true; g } else { flag = false; } resultArr.push(flag); } return resultArr; }, init: function(){ $("[class=btnNext]").click(function(){ if ($('input[type=radio]:checked:visible').length == 0) { return incorrect ; } $(this).parents('.questionContainer').fadeOut(500, function(){ $(this).next().fadeIn(500); }); var el = $('#progress'); el.width(el.width() + 11 + 'px'); }); $('.btnPrev').click(function(){ $(this).parents('.questionContainer').fadeOut(500, function(){ $(this).prev().fadeIn(500) }); var el = $('#progress'); el.width(el.width() - 11 + 'px'); }) $("[class=btnShowResult]").click(function(){ var arr = $('input[type=radio]:checked'); var ans = jQuiz.userAnswers = []; for (var i = 0, ii = arr.length; i < ii; i++) { ans.push(arr[i].getAttribute('id')) } }) $('.btnShowResult').click(function(){ $('#progress').width(260); $('#progressKeeper').hide(); var results = jQuiz.checkAnswers(); var resultSet = ''; var trueCount = 0; for (var i = 0, ii = results.length; i < ii; i++){ if (results[i] == true) trueCount++; resultSet += '<div> Question ' + (i + 1) + ' is ' + results[i] + '</div>' } resultSet += '<div class="totalScore">Your total score is ' + trueCount * 4 + ' / 100</div>' $('#resultKeeper').html(resultSet).show(); }) } }; jQuiz.init(); })

  • Doing some stuff right before the user exits the page

    - by Mike
    I have seen some questions here regarding what I want to achieve and have based what I have so far on those answer. But there is a slight misbehavior that is still irritating me. What I have is sort of a recovery feature. Whenever you are typing text, the client sends a sync request to the server every 45 seconds. It does 2 things. First, it extends the lease the client has on the record (only one person may edit at one time) for another 60 seconds. Second, it sends the text typed so far to the server in case the server crashes, internet connection fails, etc. In that case, the next time the user enters our application, the user is notified that something has gone wrong and that some text was recovered. Think of Microsoft or OpenOffice recovery whenever they crash! Of course, if the user leaves the page willingly, the user does not need to be notified and as a result, the recovery is deleted. I do that final request via a beforeunload event. Everything went fine until I was asked to make a final adjustment... The same behavior you have here at stack overflow when you exit the editor... a confirm dialogue. This works so far, BUT, the confirm dialogue is shown twice. Here is the code. The event if (local.sync.autosave_textelement) { window.onbeforeunload = exitConfirm; } The function function exitConfirm() { var local = Core; if (confirm('blub?')) { local.sync.autosave_destroy = true; sync(false); return true; } else { return false; } }; Some problem irrelevant clarifications: Core is a global Object that contains a lot of variables that are used everywhere. sync makes an ajax request. The values are based on the values that the Core.sync object contains. The parameter determines if the call should be async (default) or sync. Edit 1 I did try to separate both things (recovery deletion and user confirmation that is) into beforeunload and unload. The problem there was that unload is a bit too late. The user gets informed that there is a recovery even though it is scheduled to be deleted. If you refresh the page 1 second later, the dialogue disappears as the file was deleted by then.

  • View code inside Javascript file on Rails

    - by SpyrosP
    Hello, previously i had javascript code right in the top of my view and it would work. Then, i learned that you can include the js file using yield and i did just that. I had rails view code inside my javascript code like : $( "#exp-progressbar" ).progressbar({ value: <%= ((@quest.end_time - Time.now).to_i * 100 ) / (@quest.duration * 60) %> }); Now, after i do it with yield, i get an error when i do that in the separate js file. How can i do it now ?

  • addEventListener pass caller as argument

    - by Ryan
    Hi, I have the following code. And my problem is that when clicking, the event is firing but the argument passed is not the correct one. It is passing the last dynamically created row i.e. dataStructure.length value. Anyone knows a solution how to get around this? var table = document.getElementById('output'); for(i =0; i<dataStructure.length; i++){ var row = document.createElement('tr'); row.setAttribute('id', i); var url = dataStructure[i].url; if(document.addEventListener) row.addEventListener('click', function(){handleRowClick(i);}, false); var obj = dataStructure[i]; var cellCount = 0; for(field in obj){ var cell = document.createElement('td'); cell.setAttribute('id', cellCount++); //cell.addEventListener('click', function(){window.open(dataStructureObj.links[i].url);}, false); cell.innerHTML = obj[field]; row.appendChild(cell); } cellCount = 0; table.appendChild(row); } } function handleRowClick(rowClicked){ var rowHTML = rowClicked.innerHTML; var cells = rowHTML.getElementsByTagName('td'); for(cell in cells) { alert(cell.value); } window.open(cells[1].innerHTML); }

  • Unable to decode hex values in javascript tooltip

    - by staudk27
    Hi all, I have quite the process that we go through in order to display some e-mail communications in our application. Trying to keep it as general as possible... -We make a request to a service via XML -Get the XML reply string, send the string to a method to encode any invalid characters as follows: public static String convertUTF8(String value) { char[] chars = value.toCharArray(); StringBuffer retVal = new StringBuffer(chars.length); for (int i = 0; i < chars.length; i++) { char c = chars[i]; int chVal = (int)c; if (chVal > Byte.MAX_VALUE) { retVal.append("&#x").append(Integer.toHexString(chVal)).append(";"); } else { retVal.append(c); } } return retVal.toString(); } We then send that result of a string to another method to remove any other invalid characters: public static String removeInvalidCharacters(String inString) { if (inString == null){ return null; } StringBuffer newString = new StringBuffer(); char ch; char c[] = inString.toCharArray(); for (int i = 0; i < c.length; i++) { ch = c[i]; // remove any characters outside the valid UTF-8 range as well as all control characters // except tabs and new lines if ((ch < 0x00FD && ch > 0x001F) || ch == '\t' || ch == '\n' || ch == '\r') { newString.append(ch); } } return newString.toString(); } This string is then "unmarshal'ed" via the SaxParser The object is then sent back to our Display action which generated the response to the calling jsp/javascript to create the page. The issue is some text can contain characters which can't be processed correctly. The following is eventually rendered on the JSP just fine: <PrvwCommTxt>This is a new test. Have a*&amp;#xc7;&amp;#xb4;)&amp;#xa1;.&amp;#xf1;&amp;#xc7;&amp;#xa1;.&amp;#xf1;*&amp;#xc7;&amp;#xb4;)...</PrvwCommTxt> Which shows up as "This is a new test. Have a*Ç´)¡.ñÇ¡." in the browser. -The following shows up in a tooltip while hovering over the above text: <CommDetails>This is a new test. Have a*Ç´)¡.ñÇ¡.ñ*Ç´)¡.ñ*´)(¡.ñÇ(¡.ñÇ* Wonderful Day!</CommDetails> This then shows up incorrectly when rendered in the tooltip javascript with all the HEX values and not being rendered correctly. Any suggestions on how to make the unknown characters show correctly in javascript?

  • How to Detect an Event Coming from the Firefox History Dropdown Box

    - by banterCZ
    How to detect an event coming from the Firefox history dropdown box? I need to distinguish between the enter key simply pressed on input field or on item from his native history dropdown box. The reason is that I would like to call custom submit button (not first one, which is default) on the enter key pressed on any input field. But right now, the enter key pressed on history dropdown box unfortunately call submit as well.

  • javascript object access performance

    - by youdontmeanmuch
    In Javascript, when your getting a property of an object, is there a performance penalty to getting the whole object vs only getting a property of that object? Also Keep in mind I'm not talking about DOM access these are pure simple Javascript objects. For example: Is there some kind of performance difference between the following code: Assumed to be faster but not sure: var length = some.object[key].length; if(length === condition){ // Do something that doesnt need anything inside of some.object[key] } else{ var object = some.object[key]; // Do something that requires stuff inside of some.object[key] } I think this would be slower but not sure if it matters. var object = some.object[key]; if(object.length === condition){ // Do something that doesnt need anything inside of some.object[key] } else{ // Do something that requires stuff inside of some.object[key] }

  • JQuery: how to use "delegate" instead of "live"?

    - by JacobD
    I've read countless articles how using the JQuery delegate is much more efficient than using the "live" event. As such, I'm having trouble converting my existing Live code to using Delegate. $("#tabs li:eq(0)").live('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').live('mouseover',function(){ // ...code }); When I replace the previous code with what I assume is more efficient delegate code, my page doesn't load. $("#tabs li:eq(0)").delegate('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').delegate('mouseover',function(){ // ...code }); Any idea why my delegate code doesn't work? Also, any suggestions on how to make this more efficient? UPDATE: The think part of the problem is that, both "#tabs" and "#A, #B, #C" are't present on the web page at page load. Those attributes are dynamically inserted onto the page with an AJAX call. As such, does that mean I have to use live over delegate?

  • how to add markup to text using JavaScript regex

    - by Richard
    I need to add markup to some text using JavaScript regular expressions. In Python I could do this with: >>> import re >>> re.sub('(banana|apple)', r'<b>{\1}</b>', 'I have 1 banana and 2 apples!') 'I have 1 <b>{banana}</b> and 2 <b>{apple}</b>s!' What is the equivalent in JavaScript? string.replace(regex, newstring) seems to only take a raw string for replacing.

  • HtmlUnit doesn't load externally referenced javascript

    - by nici
    I have run into a problem while trying to test a web application with HtmlUnit. Please bear in mind that I haven't used HtmlUnit very long so I might be missing something trivial. For some reason externally referenced javascripts aren't being loaded. When I print the page as xml all i get is this: <script language="javascript" src="urltofile.js"> </script> As you can see the script tag is empty when it should contain the javascript. What am I missing? I have googled for a solution all morning but haven't found any relevant information. Any help would be greatly appreciated!

  • Rails 3: How do I call a javascript function from a js.erb file

    - by user321775
    Now that I've upgraded to Rails 3, I'm trying to figure out the proper way to separate and reuse pieces of javascript. Here's the scenario I'm dealing with: I have a page with two areas: one with elements that should be draggable, the other with droppables. When the page loads I use jQuery to setup the draggables and droppables. Currently I have the script in the head portion of application.html.erb, which I'm sure is not the right solution but at least works. When I press a button on the page, an ajax call is made to my controller that replaces the draggables with a new set of elements that should also be draggable. I have a js.erb file that renders a partial in the correct location. After rendering I need to make the new elements draggable, so I'd like to reuse the code that currently lives in application.html.erb, but I haven't found the right way to do it. I can only make the new elements draggable by pasting the code directly into my js.erb file (yuck). What I'd like to have: - a javascript file that contains the functions prepdraggables() and prepdroppables() - a way to call either function from application.html.erb or from a js.erb file I've tried using :content_for to store and reuse the code, but can't seem to get it working correctly. What I currently have in the head section of application.html.erb <% content_for :drag_drop_prep do %> <script type="text/javascript" charset="utf-8"> $(document).ready(function () { // declare all DOM elements with class draggable to be draggable $( ".draggable" ).draggable( { revert : 'invalid' }); // declare all DOM elements with class legal to be droppable $(".legal").droppable({ hoverClass : 'legal_hover', drop : function(event, ui) { var c = new Object(); c['die'] = ui.draggable.attr("id"); c['cell'] = $(this).attr("id"); c['authenticity_token'] = encodeURIComponent(window._token); $.ajax({ type: "POST", url: "/placeDie", data: c, timeout: 5000 }); }}); }); </script> <% end %> undo.js.erb $("#board").html("<%= escape_javascript(render :partial => 'shared/board', :locals => { :playable => true, :restartable => !session[:challenge]}) %>") // This is where I want to prepare draggables. <%= javascript_include_tag "customdragdrop.js" %> // assuming this file had the draggables code from above in a prepdraggables() function prepdraggables();

  • MooTools Problem in IE with Request

    I have this class method in a mootools class: getData : function(){ var r = new Request.JSON({ url : this.container.getAttribute('data-url'), method : 'post', onSuccess : function(j){ this.cards = j; this.prepareQuiz(); }.bind(this) }).send(); }, In any browser aside from IE this works fine, but in IE I get a this.cards is not defined in a method that occurs after the this.prepareQuiz method does it's stuff. I narrowed the problem to this section by adding an if ($defined(this.cards)) before the this.prepareQuiz call and if I just keep refreshing the page 1 out of every 5 or so times it will work. So the this.cards variable is not being set some of the time for some reason. Why would this happen?
