  • Ajax Request not working. onSuccess and onFailure not triggering

    - by Kye
    Hi all, trying to make a page which will recursively call a function until a limit has been reached and then to stop. It uses an ajax query to call an external script (which just echo's "done" for now) howver with neither onSuccess or onFailure triggering i'm finding it hard to find the problem. Here is the javascript for it. In the header for the webpage there is a script to an ajax.js document which contains the request data. I know the ajax.js works as I've used it on another website var Rooms = "1"; var Items = "0"; var ccode = "9999/1"; var x = 0; function echo(string,start){ var ajaxDisplay = document.getElementById('ajaxDiv'); if(start) {ajaxDisplay.innerHTML = string;} else {ajaxDisplay.innerHTML = ajaxDisplay.innerHTML + string;} } function locations() { echo("Uploading location "+x+" of " + Rooms,true); Ajax.Request("Perform/location.php", { method:'get', parameters: {ccode: ccode, x: x}, onSuccess: function(reply) {alert("worked"); if(x<Rooms) { x++; locations(); } else { x=0; echo("Done",true); } }, onFailure: function() {alert("not worked"); echo("not done"); } }); alert("boo"); } Any help or advice will be most appreciated.

  • [JS/jQuery] Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • Loading xml with Jquery - why doesn't this work

    - by es11
    I have regular javascript code and am trying to utilize JQuery just to load and parse an xml file. I have the following: function loadXml() { $(function() { $.ajax({ type: "GET", url: "my_file.xml", dataType: "xml", success: parseXml }); }); } function parseXml() { alert("Parsing..."); } When calling loadXml I cannot get the callback success function to execute. I am running this all locally and my_file.xml resides in the same directory as this javascript. Any ideas?

  • MMGR Questions, code use and thread-saftey

    - by chadb
    1) Is MMGR thread safe? 2) I was hoping someone could help me understand some code. I am looking at something where a macro is used, but I don't understand the macro. I know it contains a function call and an if check, however, the function is a void function. How does wrapping "(m_setOwner (FILE,_LINE_,FUNCTION),false)" ever change return types? #define someMacro (m_setOwner(__FILE__,__LINE__,__FUNCTION__),false) ? NULL : new ... void m_setOwner(const char *file, const unsigned int line, const char *func); 3) What is the point of the reservoir? 4) On line 770 ("void *operator new(size_t reportedSize)" there is the line "// ANSI says: allocation requests of 0 bytes will still return a valid value" Who/what is ANSI in this context? Do they mean the standards? 5) This is more of C++ standards, but where does "reportedSize" come from for "void *operator new(size_t reportedSize)"? 6) Is this the code that is actually doing the allocation needed? "au-actualAddress = malloc(au-actualSize);"

  • javascript watching for variable change via a timer

    - by DA
    I have a slide show where every 10 seconds the next image loads. Once an image loads, it waits 10 seconds (setTimeout) and then calls a function which fades it out, then calls the function again to fade in the next image. It repeats indefinitely. This works. However, at times, I'm going to want to over-ride this "function1 call - pause - function2 call - function1 call" loop outside of this function (for instance, I may click on a slide # and want to jump directly to that slide and cancel the current pause). One solution seems to be to set up a variable, allow other events to change that variable and then in my original function chain, check for any changes before continuing the loop. I have this set up: var ping = 500; var pausetime = 10000; for(i=0; i<=pausetime; i=i+ping){ setTimeout(function(){ console.log(gocheckthevariable()); console.log(i); pseudoIf('the variable is true AND the timer is done then...do the next thing') },i) } The idea is that I'd like to pause for 10 seconds. During this pause, every half second I'll check to see if this should be stopped. The above will write out to the console the following every half second: true 10000 true 10000 true 10000 etc... But what I want/need is this: true 0 true 500 true 1000 etc... The basic problem is that the for loop executes before each of the set timeouts. While I can check the value of the variable every half second, I can't match that against the current loop index. I'm sure this is a common issue, but I'm at a loss what I should actually be searching for.

  • Select list value undefined in $(document).ready

    - by C. Ross
    I have the following code, which I want to load values on a selection change, and also do the selection load initially (since FF 'saves' the last value of the drop down under certain circumstances). The select part of the function works correctly, but for some reason when calling load2 directly the value of $('#select1').value is undefined, even though when I check the DOM in Firebug right after load select1.value has a value. How can I run the load2 function when select1.value is ready? $(document).ready(function() { //Setup change hook $('#select1').change(function(event) { //Remove the old options right away $('#select2').find('option').remove(); //Load the new options load2(this.value); }); //Do load for current value load2($('#select1').value); });

  • Need some help synch'ing outer loop counter with dialog.onconfirm()

    - by Chris Barnhill
    I am writing a game for Facebook. IN the following code, I have a problem. I have a for loop executing, and in that loop, I call a dialog and implement 'onconfirm' for the dialog. The problem is that I need to access th e loop counter inside of the onconfirm function. But because the onconfirm is called outside of the scope of the for loop, the counter value is no longer valid because it's been incremented. I need some way to pass the counter value to the dialog onconfirm as it was at the time the dialog was displayed, not after the loop has finished. Or maybe someone has a better solution. Any help would be appreciated. Thanks. function unloadCargo() { //debugger; var actionPrompt = document.getElementById('action-prompt'); actionPrompt.setTextValue('Unloading cargo...'); var ajax = new Ajax(); ajax.responseType = Ajax.JSON; ajax.ondone = function(data) { debugger; if(data.unloadableCargo.length == 0) { loadCargo(); } else { //console.log('unloadable cargo='+dump(data.unloadableCargo)); var i = 0; var j = 0; var ucCount = data.unloadableCargo.length; for(i = 0; i < ucCount; i++) { cargoDialog = new Dialog(); cargoDialog.showChoice('Unload Cargo', 'Unload ' + data.unloadableCargo[i].goods_name + ' at ' + data.unloadableCargo[i].city_name + ' for ' + data.unloadableCargo[i].payoff + 'M euros?'); cargoDialog.onconfirm = function() { //console.log('unloadable cargo onconfirm='+dump(data.unloadableCargo)); var ajax = new Ajax(); var param = {"city_id": data.unloadableCargo[i].city_id, "goods_id": data.unloadableCargo[i].goods_id, "payoff": data.unloadableCargo[i].payoff}; ajax.ondone = function(demandData) { var demands = document.getElementById('demands'); var innerXhtml = '<span>'; for(var j = 0; j < demandData.demands.length; j++) { innerXhtml = innerXhtml + ' <div class="demand-item"><div class="demand-city">' + demandData.demands[j].city + '</div><div class="demand-pay">' + demandData.demands[j].cost + '</div><div class="demand-goods">' + demandData.demands[j].goods + '</div></div>'; } innerXtml = innerXhtml + ' </span>'; demands.setInnerXHTML(innerXhtml); // update balance loadCargo(); } ajax.post(baseURL + "/turn/do-unload-cargo", param); } cargoDialog.oncancel = function() { loadCargo(); } } //loadCargo(); } } ajax.post(baseURL + '/turn/unload-cargo'); }

  • Javascript: variable scope & the evils of globals

    - by Nick
    I'm trying to be good, I really am, but I can't see how to do it :) Any advice on how to not use a global here would be greatly appreciated. Let's call the global G. Function A Builds G by AJAX Function B Uses G Function C Calls B Called by numerous event handlers attached to DOM elements (type 1) Function D Calls B Called by numerous event handlers attached to DOM elements (type 2) I can't see how I can get around using a global here. The DOM elements (types 1 & 2) are created in other functions (E&F) which are unconnected with A. I don't want to add G to each event handler (because it's large and there's lots of these event handlers), and doing so would require the same kind of solution as I'm seeking here (i.e., getting G to E&F). The global G, BTW, is an array that is necessary to build other elements as they, in turn, are built by AJAX. I'm not convinced that a singleton is real solution, either. Thanks.

  • Slider with buttons. How to improve?

    - by Kalinin
    I need to make slider. I have content (which should shift horizontally) and two buttons - "right" and "left". If you press the button and hold it, the content starts to move (in the appropriate direction). If you not hold the button, then the movement stops. This behavior is copies the behavior of usual window scrollbar. I wrote code: var animateTime = 1, offsetStep = 5; //event handling for buttons "left", "right" $('.bttR, .bttL') .mousedown(function() { scrollContent.data('loop', true).loopingAnimation($(this)); }) .bind("mouseup mouseout", function(){ scrollContent.data('loop', false); }); $.fn.loopingAnimation = function(el){ if(this.data('loop') == true){ var leftOffsetStr; leftOffsetInt = parseInt(this.css('marginLeft').slice(0, -2)); if(el.attr('class') == 'bttR') leftOffsetStr = (leftOffsetInt - offsetStep).toString() + 'px'; else if(el.attr('class') == 'bttL') leftOffsetStr = (leftOffsetInt + offsetStep).toString() + 'px'; this.animate({marginLeft: leftOffsetStr}, animateTime, function(){ $(this).loopingAnimation(el); }) } return this; } But it does have a few things that I do not like: Always call the function animation (loopingAnimation) - I think that this is an extra load (not good). When moving content he "twitches and trembling" - (it's not pretty). How can I solve this problem more elegantly and without the drawbacks of my code?

  • Problem with JQuery swapImage();

    - by VUELA
    Hello!~ On my articles page (http://www.adrtimes.squarespace.com/articles) I have each entry start with an image that changes on rollover. This is working fine. However, on my homepage (http://www.adrtimes.squarespace.com), I am loading in the 2 most recent articles that are not categorized as video, and the 2 most recent articles that are tagged as video. I am using jQuery load() to pull in the content from the articles page. Everything works ok with that except the swapImage rollovers on the homepage. i tried including the swapImage function as callbacks but only one group or the other will rollover properly, not both groups of content. I'm not sure what the problem is!! Here is the code: <script type="text/javascript"> <!-- $(function(){ $.swapImage(".swapImage"); /* Homepage */ // load recent articles $("#LoadRecentArticles").load("/articles/ .list-journal-entry-wrapper .journal-entry-wrapper:not(.category-video)", function(){ //callback... $("#LoadRecentArticles .journal-entry-wrapper").wrapAll('<div class="list-journal-entry-wrapper" />'); $("#LoadRecentArticles .journal-entry-wrapper:gt(1)").remove(); // modify Read More tag $('.journal-read-more-tag a:contains(Click to read more ...)').each(function(){ var str = $(this).html(); $(this).html(str.replace('Click to read more ...','Continue reading—')); }); $.swapImage(".swapImage"); }); // load recent videos $("#LoadRecentVideos").load("/articles/category/video .list-journal-entry-wrapper", function(){ //callback... $("#LoadRecentVideos .journal-entry-wrapper:gt(1)").remove(); $('<div class="VideoTag">—video</div>').insertBefore("#LoadRecentVideos .category-video .body img"); // modify Read More tag $('.journal-read-more-tag a:contains(Click to read more ...)').each(function(){ var str = $(this).html(); $(this).html(str.replace('Click to read more ...','Continue reading—')); }); $.swapImage(".swapImage"); }); }); --> </script> And here is a sample of the html for the images in an article entry: <a href="/articles/2010/5/6/article-title-goes-here.html"><img class="swapImage {src: '/storage/post-images/Sample2_color.jpg'}" src="/storage/post-images/Sample2_bw.jpg" /></a>

  • After .load() Reset Textbox with User Entered Value using JavaScript and jQuery

    - by Aaron Salazar
    My function below calls a partial view after a user enters a filter-by string into the text box '#DocId'. When the user is done typing, the partial view is displayed with filtered data. Since my textbox needs to be in the partial view, when user is done entering a filter-by string and is shown the filtered data, the textbox is reset and the user entered data is lost. How can I set the value of the textbox back to the user entered string after the partial view is displayed? I'm pretty sure I need to use .val() but I can't seem to get this to work. $(function() { $('#DocId').live('keyup', function() { clearTimeout($.data(this, 'timer')); var val = $(this).val(); var wait = setTimeout(function() { $('#tableContent').load('/CurReport/TableResults', { filter: val }, 500) }, 500); $(this).data('timer', wait); }); }); Thank you, Aaron

  • jquery live() method on custom functions

    - by user271619
    I have a custom event handler, or I suppose some call it a custom jquery function. My problem is I'm trying to apply the live() method to it. But I'm not too successful. Here's a simple custom jquery function: $.fn.myFunction = function() { return $(this).addClass('changed'); } And here I use it: $('.changePlease').myFunction(); Ok, simple enough. But how do I apply the live() method to it?? I actually have no idea if that's even possible. But I do use live() for other things, like: $(".changePlease").live("click",function(){ alert("hello"); }); Any thoughts on this?

  • casting BSTR as char* in a dll; different results depnding on VB/C# caller.

    - by Toby Wilson
    I have a dll function that takes BSTR parameters. These are casted as char* before being used for other things. When the dll is called from VB code this works fine. However, when it is called from C# code, only the first character is pointed to. Both of these are excel addIns for Pre-2007 and 2007+ versions of Office, which call into a faster C++ AddIn. They actually call it directly, not through Excel. The VB function declaration looks like this: Private Declare Function Test Lib "ExcelAddIn.xll" (ByVal param As String) As String The C# function declaration looks like this: [DllImport("ExcelAddIn.xll", CharSet=CharSet.Ansi)] [return:MarshalAs(UnmanagedType.BStr)] private static extern string Test([MarshalAs(UnmanagedType.BStr)] string param); When debugging the dll and watching the input BSTR values, they appear to be correct from both; just the C# one only casts the first character. Charset=CharSet.Unicode makes no difference. Any ideas anyone?

  • How to determine loading status of images not attached to the DOM

    - by Rookwood
    I am working on a bit of javascript to plot data on a <canvas. The data points are marked by one of several different (small) image files. I am attempting to have the plot method wait until all the images are loaded. My best attempt thus far is such: var icon = { left : { air : new Image(), bone : new Image(), }, right : { air: new Image(), bone : new Image(), }, }; icon.left.air.src = option.imgPath + 'left.air.png'; icon.right.air.src = option.imgPath + 'right.air.png'; icon.left.bone.src = option.imgPath + 'left.bone.png'; icon.right.bone.src = option.imgPath + 'right.bone.png'; function main() { Canvas.draw(); // Make sure our image icons are loaded before we try to plot $(icon.left.air).load(function() { $(icon.right.air).load(function() { $(icon.left.bone).load(function() { $(icon.right.bone).load(function() { Data.plot(); }); }); }); }); } This works as expected most of the time. On occasion, it will fail and no data will be plotted. Inserting several console.log() statements shows that the script will silently stop working through the series of .load() statements, though code that comes after will be executed. My questions are as follows: Am I approaching this the right way? Is there a way to attach an event to my icon object that will fire once all of the images inside are loaded? This is a jquery plugin, so obviously jquery-based solutions are just as acceptable as vanilla javascript.

  • Global variables that can be used in multiple jQuery functions

    - by YouBook
    Can you be able to contain variables that can be used in multiple functions in jQuery, example: var self = $(this); var box = self.parents('.box'); $('#title').click(function() { self.css('background', 'red'); box.slideDown('slow'); }).dblclick(function() { self.css('background', 'green'); box.slideUp('slow'); }); So that self and box can be used within these event functions so I don't have to keep doing this: $('#title').click(function() { var self = $(this); var box = self.parents('.box'); self.css('background', 'red'); }).dblclick(function() { var self = $(this); var box = self.parents('.box'); self.css('background', 'green'); }); But question is, is it possible, if so, how can you do that?

  • Calling a jQuery plugin inside itself

    - by Real Tuty
    I am trying to create a comet like thing. I have a plugin that collects data from a php page. The problem is that i dont know how to call the plugin inside itself. If it were a function i could go like this: function j () {setTimeout(j(), 1000);}, but i am using a jQuery plugin. Here is my plugin code: (function($) { $.fn.watch = function(ops) { var $this_ = this, setngs = $.extend({ 'type' : 'JSON', 'query' : 'GET', 'url' : '', 'data' : '', 'wait' : 1000 }, ops); if (setngs.type === '') { return false; } else if (setngs.query === '') { return false; } else if (setngs.url === '') { return false; } else if (setngs.wait === '') { return false; } else if (setngs.wait === 0) { setngs.wait = 1000; } var xhr = $.ajax({ type : setngs.query, dataType : setngs.type, url : setngs.url, success : function(data) { var i = 0; for (i = 0; i < data.length; i++) { var html = $this_.html(), str = '<li class="post" id="post-' + data[i].id + '"><div class="inner"><div class="user">' + data[i].user + '</div><div class="body">' + data[i].body + '</div></div></li>'; $this_.html(str + html); } setTimeout($this_, 1000); } }); }; })(jQuery); where it says setTimeout($this_, 1000); this is where im having trouble. I don't know what to call the plugin as. $this_ is what I thought might work but I am wrong. That is what i need to replace. Thanks for your help.

  • How to copy a variable in JavaScript?

    - by Michael Stum
    I have this JavaScript code: for (var idx in data) { var row = $("<tr></tr>"); row.click(function() { alert(idx); }); table.append(row); } So I'm looking through an array, dynamically creating rows (the part where I create the cells is omitted as it's not important). Important is that I create a new function which encloses the idx variable. However, idx is only a reference, so at the end of the loop, all rows have the same function and all alert the same value. One way I solve this at the moment is by doing this: function GetRowClickFunction(idx){ return function() { alert(idx); } } and in the calling code I call row.click(GetRowClickFunction(idx)); This works, but is somewhat ugly. I wonder if there is a better way to just copy the current value of idx inside the loop? While the problem itself is not jQuery specific (it's related to JavaScript closures/scope), I use jQuery and hence a jQuery-only solution is okay if it works.
