  • send datas to php with ajax - Internal Server Error(500)

    - by user1277467
    i try to send my datas to php with ajax but there's strange mistake. this is my ajax script, function deleteData2() { var artistIds = new Array(); $(".p16 input:checked").each(function(){ artistIds.push($(this).attr('id')); }); $.post('/json/crewonly/deleteDataAjax2', { json: JSON.stringify({'artistIds': artistIds}) }, function(response){ alert(response); }); } i think this works correctly but in php side, i face 500 internal server error(500). public function deleteDataAjax2() { $json = $_POST['json']; $data = json_decode($json); $artistIds = $data['artistIds']; $this->sendJSONResponse($artistIds); } Above code is my php. For example, when i try to send $data to ajax, i print my ids in json mode: However, when i try to send $artistIds to ajax side, i gives 500 error why?

  • 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>

  • Dynamic jQuery dialog after data append w/o reloading page. Possible?

    - by Arun
    Howdy, So I have a page with an enormous table in a CRUD interface of sorts. Each link within a span calls a jQuery UI Dialog Form which fetches it's content from another page. When the action taking place (in this case, a creation) has completed, it appends the resulting new data to the table and forces a resort of the table. This all happens within the JS and the DOM. The problem with this, is that the new table row's CRUD links don't actually trigger the dialog form creation as all the original links in spans are only scanned on document.ready and since I'm not reloading the page, the new links cannot be seen. Code is as follows: $(document).ready(function() { var $loading = $('<img src="/images/loading.gif" alt="Loading">'); $('span a').each(function() { var $dialog = $('<div></div>') .append($loading.clone()); var $link = $(this).one('click', function() { // Dialog Stuff success: function(data) { $('#studies tbody').append( '<tr>' + '<td><span><a href="./?action=update&study=' + data.study_id + '" title="Update Study">Update</a></span></td>' + '</tr>' ); fdTableSort.init(#studies); // This re-sorts the table. $(this).dialog('close'); } $link.click(function() { $dialog.dialog('open'); return false; }); return false; }); }); }); Basically, my question is if there is any way in which to trigger a jQuery re-evaluation of the pages links without forcing me to do a browser page refresh?

  • Highlight multiple rows using jQuery

    - by cf_PhillipSenn
    I'm putting together a succinct jQuery matrix because I'm having a hard time navigating around on the jQuery site, and the cheat sheets don't seem to provide me what I want either. Here's how I highlight the rows: $('.eq').hover(function() { $('.eq').toggleClass('highlight'); }); $('.is').hover(function() { $('.is').toggleClass('highlight'); }); Q: How can I write a function that says "toggle everything in the same class as what is being hovered over"? Something like: function toggle(that){ $(that.className).toggleClass('highlight'); }

  • jQuery: Any way to "refresh" event handlers?

    - by Legend
    I have two divs, one that holds some stuff and the other with all possible stuff. Clicking on one of the divs will transfer items to the other div. The code I came up with is: $("#holder > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#bucket").append(this); }); }); $("#bucket > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#holder").append(this); }); }); This one works perfectly, except that the event handlers need to be refreshed once I append or remove elements. What I mean is, if I first click on an element, it gets added to the other div, but if I click on this element again, nothing happens. I can do this manually but is there a better way to achieve this?

  • Google Apps Script: how to make suggest box library to work?

    - by Pythonista's Apprentice
    I'm trying to add an autocomplete feature in my Google Spreadsheet using this Google Apps Script suggest box library from Romain Vialard and James Ferreira's book: function doGet() { // Get a list of all my Contacts var contacts = ContactsApp.getContacts(); var list = []; for(var i = 0; i < contacts.length; i++){ var emails = contacts[i].getEmails(); if(emails[0] != undefined){ list.push(emails[0].getAddress()); } } var app = UiApp.createApplication(); var suggestBox = SuggestBoxCreator.createSuggestBox(app, 'contactPicker', 200, list); app.add(suggestBox); return app; } function onEdit() { var s = SpreadsheetApp.getActiveSheet(); if( s.getName() == "my_sheet_name" ) { //checks that we're on the correct sheet var r = s.getActiveCell(); if( r.getColumn() == 1) { doGet(); } } } But when I start editing the column 1 of "my_sheet_name" nothing hapens (if I replace doGet() for other function, this other function runs Ok). I've already installed the Suggest Box library. So, why the doGet() function doesn't work?

  • Is possible to initialize an object in javascript in this way?

  • setTimeout is acting weird

    - by mnish
    I am trying to make a simple setTimeout, to make a div tag invisible after 2 seconds. The setTimeout function makes the div invisible but irregularly, sometimes immediately and sometimes after 1 sec, and so on. Here is my code: function beginTimeOut(){ t = setTimeout(function(){hideSubMenu()},2000); } function hideSubMenu(){ var elem; elem = document.getElementById("ul_navlist1"); elem.style.visibility="hidden"; clearTimeout(t); } By the way, t is a global variable. I have tried this too: t = setTimeout("hideSubMenu()",2000); but with the same irregular results.

  • switch easily between different main()

    - by lezebulon
    I'm using VS2010 I have a project with several headers and one file with the main() function. For testing purposes I'd like to be able to easily another main() function that would instanciate different things than my original main. Is there an easy way to define 2 "main" function, and easily switch between them? The best would be to compile 2 binaries, one that starts at main1() and the other at main2(), or it can be a solution that requires to recompile some files, it doesn't matter

  • Ordering z-indexes in an array

    - by Tom Gullen
    I have an array which looks something along the lines of resourceData[0][0] = "pic1.jpg"; resourceData[0][1] = 5; resourceData[1][0] = "pic2.jpg"; resourceData[1][1] = 2; resourceData[2][0] = "pic3.jpg"; resourceData[2][1] = 900; resourceData[3][0] = "pic4.jpg"; resourceData[3][1] = 1; The numeric represents the z-index of the image. Minimum z-index value is 1. Maximum (not really important) is 2000. I have all the rendering and setting z-indexes done fine. My question is, I want to have four functions: // Brings image to z front function bringToFront(resourceIndex) { // Set z-index to max + 1 resourceData[resourceIndex][1] = getBiggestZindex() + 1; // Change CSS property of image to bring to front $('#imgD' + resourceIndex).css("z-index", resourceData[resourceIndex][1]); } function bringUpOne(resourceIndex) { } function bringDownOne(resourceIndex) { } // Send to back z function sendToBack(resourceIndex) { } So given then index [3] (900 z): If we send it to the back, it will take the value 1, and [3] will have to go to 2, but that conflicts with [1] who has a 2 z-index so they need to go to three etc. Is there an easy programatical way of doing this because as soon as I start doing this it's going to get messy. It's important that the indexes of the array don't change. We can't sort the array unfortunately due to design. Update Thanks for answers, I'll post the functions here once they are written incase anyone comes across this in the future (note this code has zindex listed in [6]) // Send to back z function sendToBack(resourceIndex) { resourceData[resourceIndex][6] = 1; $('#imgD' + resourceIndex).css("z-index", 1); for (i = 0; i < resourceData.length; i++) { if (i != resourceIndex) { resourceData[i][6]++; $('#imgD' + i).css("z-index", resourceData[i][6]); } } }

  • Responsive: two different toggles on same element

    - by Mathijs Delva
    I'm having difficulties with the following problem. For a responsive website, i need to use the same toggle element for both a toggle system for one window width, and another toggle system for a second window width. I have the following snippets: 1.A simple hover for a language dropdown, which should be executed for resolutions greater than 980px. $('#clickme').hover(function() { $(this).parent().find("#select-language").show(); $(this).find("> a span").css({"opacity":"0.5"}); }, function() { $(this).parent().find("#select-language").hide(); $(this).find("> a span").css({"opacity":"1"}); }); 2.A simple click for the same language toggle, which should be executed for resolutions smaller than 980px. jQuery('#clickme').click(function() { jQuery("#select-language-mobile").slideToggle("fast"); }); I need to nest these two, so that when the user is viewing the website in one resolution, the click function with be fired, and in the other case the hover function. Can anybody help me with this? PS: I'm sorry, but the code blocks don't seem to work at the moment.

  • Making a Delete and Reply button in Jquery

    - by Branko Ostojic
    this is my second post on the website. Of all other sites i tried, this one gave the most accurate and useful information! I'm in a bit of a trouble with buttons, i have a task to make an inbox and to add a "reply" and "delete" button into every instance of the message. I was indeed wandering if there is a better way to do that than forcing the HTML code into the script, because every message is dynamically generated. Any help and/or suggestions would be very appreciated!(The objects are called from a JSON file). $(document).ready(function(){ $.getJSON('public/js/data.json', function(json){ $.each(json.data, function(i, data){ var output = ''; if(data.from.id != '234' && data.from.name != 'Alan Ford'){ $("#inbox").append( output += '<div class="post">'+ '<div class="h1">'+data.from.name+' - '+data.subject+'</div>'+ //this gives the name of the person who sent the message and the subject '<div class="content">'+data.message_formatted+'</div>'+ //The content of the message //buttons should be squeezed left of the date //this gives the date of the message sent '<div class="time">'+data.date_sent_formatted.formatted+'</div>'+ '</div>' ); }}); }); }); var date_sent=convertToDateTime(); function delete_message(id){ console.log('Delete message with id: '+id); } function reply_message(id, sender){ console.log('Message id: '+id); console.log('Reply to: '+sender); } The complete code in the JSFiddle . Just copy/pasted!

  • How to handle error in this case? By Exceptions or boolean or something else

    - by TP
    I am trying to create a Response class in Java which has a method void setResponse(String response); Different response subclasses will have different requirements for the response. The string that is passed to the function is received from the user. What is the correct way of handling a wrong response? Should the function throw an exception like IllegalResponseException Should the function be declared like boolean setResponse(String response, String errorMsg) and return false if the response is wrong and set the error message to the appropriate value

    - by Y_Y
    I have 1 function that I want to return the address of an assigned string to the main function and assign an new string pointer with the same address so that the new string will have the contents of the old string. For example: unknown_datatype function() { char *old = "THE STRING"; return old; } int main() { char *snew = ""; snew = function(); return 0; } *unknown_datatype means I don't know that to put there... *How can I approach this without changing anything in the main() method

  • How do you make the script wait for the status of an Ajax get request before continuing?

    - by codeninja
    Basically what I'm doing is checking for the existence of an object, if it's not found, the script will try to load the source file using getScript. I only want to check this once though then return true or false to the function that calls fetch() fetch:function(obj){ ... isReady = false; $.getScript(obj.srcFile,function(){ isReady=true; warn("was able to load object "+key); }); return isReady; } but return kicks in before the script loads =/ later the script is loaded but the function returned false. This is the beauty of asynchronous I suppose... What's the best way to handle this... Maybe I could check again at some other point if the object exists? Or maybe there's a better way to do this where I dont have to potentially lock the browser?
