  • Inserting new <TD> elements into a table row.

    - by Hunter S. Smythe
    I have created a small application written in XHTML, JavaScript/JQuery and PHP. The PHP reads and writes to a small SQLite database. How would i go about inserting cells into a pre-scripted table. The cells would need to be configured using some information from my database. For example, below are two cells with their data retrieved from my database: Cell One Starts: 120px; Finishes: 180px; Background: Blue; Cell Two Starts: 240px; Finishes: 300px; Background: Green; On my table row, it is 500px in width. How would I insert the cells above into the row. In this example, the first cell would start 120px into the row and have a width of 180px. The second cell would start 240px into the row and have a width of 300px. I just cant seem to work out a way of doing this, any ideas would be very helpful. Thank you for any input, all is appreciated. Hunter.

  • onfocus="this.blur();" problem

    - by carpenter
    // I am trying to apply an "onfocus="this.blur();"" so as to remove the dotted border lines around pics that are being clicked-on // the effect should be applied to all thumb-nail links/a-tags within a div.. // sudo code (where I am): $(".box a").focus( // so as to effect only a tags within divs of class=box | mousedown vs. onfocus vs. *** ?? | javascript/jquery... ??? function () { var num = $(this).attr('id').replace('link_no', ''); alert("Link no.

  • how to match var/id to class

    - by circey
    Hi. I'm new to jquery and, in addition, I think I'm having a brain freeze. I have a number of links with different ids. I want to match the clicked link with a div with the corresponding class so the div will show/hide/toggle as appropriate. I have: <script type="text/javascript"> $(document).ready(function() { $('.folioBox').hide(); $('a.interface').click(function(){ var currentId = $(this).attr('id'); var currentBox = $('.folioBox .' + currentId); $(currentBox).toggle(400); }); }); </script> <a class="interface" id="apple">Apple flavor</a> <a class="interface" id="banana">Banana flavor</a> <a class="interface" id="cherry">Cherry flavor</a> <div class="folioBox apple">content</div> <div class="folioBox banana">content</div> <div class="folioBox cherry">content</div> I just can't get it to work and I can't figure out whether I would be best using match or find or filter. Some assistance would be much appreciated!

  • jeditable not updating browser display - leaves "click to edit..." after succesful edit

    - by Enoch
    I am using jeditable fairly simply and it all works fine, updates the database, etc. The only problem I have is after the user types the new value data and hits enter it doesn't update the field in the browser to show the new value - instead it puts "Click to edit..." in place of it. Am I missing something like a return value from my php file? the php fucntion just takes the args and updates the database - and it works fine. Enoch the jquery\jeditable code $('.edit').editable('update.php',{ id: 'field', name: 'val', indicator: 'Saving...', tooltip: 'Click to edit...', select : true, submitdata : { db : "pers", kn : "key", rec : "?php echo $rec; ?" } }); the div <div class="edit" id="svc_ad1"><?php echo $row-svc_ad1; ?>< /div> i also have a css class for pEdit edit{ float:left; width:200px; height:15px; margin-bottom:5px; border-bottom:1px solid #aaaaaa; }

  • cannot get thickbox to open / tb_show function ignored

    - by user357034
    I have two links that should open up thickbox's in iframes but only one works (the one with the id of product_photo_zoom_url2). I have the following jquery code that works when this code... All that happens when the first zoom image is clicked is the page goes to the top so it seems that the .click bind is being ignored? How do I get this to work? onload="vZoom.add(this, '/v/vspfiles/photos/70367301P-2.jpg');" / is removed from the markup. The above code loads a picture zoom function. See complete markup below. var titleattr = $("a#product_photo_zoom_url").attr("title"); function picurl() { tb_show(titleattr, '/PhotoDetails.asp?ShowDESC=N&ProductCode='+ global_URL_Encode_Current_ProductCode + '&TB_iframe=true&height=600&width=520');return false; } $("a#product_photo_zoom_url").click(picurl); $("a#product_photo_zoom_url2").click(picurl); $("a#product_photo_zoom_url").attr('href', '#'); $("a#product_photo_zoom_url2").attr('href', '#'); Here is the html code <a id="product_photo_zoom_url" href="/PhotoGallery.asp?ProductCode=70367301P" title="70367301P Ignition Box"> <img id="product_photo" src="/v/vspfiles/photos/70367301P-2T.jpg" border="0" alt="70367301P Ignition Box" onload="vZoom.add(this, '/v/vspfiles/photos/70367301P-2.jpg');" /></a>

  • Ajax model binding of a complex type

    - by David G
    I am trying to do something along the lines of the following where I have a Controller with an method similar to: public ActionResult Insert(Author author) { //do something... } Where the Author type looks like: public class Author { public string FirstName { get; set; } public string LastName { get; set; } public Book[] Books { get; set; } public Author() { Books = new Book[0]; } } public class Book { public string Title { get; set; } public int NumberOfPages { get; set; } } From a page I want to submit data using JQuery and Ajax something like function addAuthor() { var auth = { 'FirstName': 'Roald', 'LastName': 'Dahl', 'Books': [ { 'Title': 'Charlie and the Chocolate Factory', 'NumberOfPages': 264 }, { 'Title': 'The Twits', 'NumberOfPages': 316 } ] }; $.ajax({ type: "GET", url: "/Insert", data: auth }); } MVC binds the Author object (FirstName and LastName are set) but doesn't bind the Books property. Why is that and how can I submit an object containing an Array (or a Collection) as a property through AJAX?

  • setInterval works only the first time

    - by Neil
    Hi, I am trying to use setTimer to animate a slide show using straightforward jQuery. I provide the user with a button (in the form of a "DIV" with a button background image) that he clicks to start the show and which then turns into a pause button. The slides are supposed to change every 3 seconds. Here is the relevant code: playLink = $('<div id="lbPlayLink" />').click(function(){ $(playLink).hide(); $(pauseLink).show(); slideInterval = setInterval(function(){next()}, 3000) })[0]; pauseLink = $('<div id="lbPauseLink" />').click(function(){ $(playLink).show(); $(pauseLink).hide(); clearInterval(slideInterval); }).hide()[0]; The next() function call does the work of replacing the slide with the next one. I have checked out this function and it works perfectly if I call it directly (synchronously), however, when it gets called asonchronously by the "setInterval", it works fine the first time (3 seconds after I click on the button), but is never called again, even though it should be called 3 seconds later. I know it's never called as I put an "alert" call at the beginning and end of the function. If I replace the "next()" call in the "setInterval" by "alert('test')" then I can see the setInterval is doing what it is supposed to. I can't for the life of me see why "alert()" is OK but "next()" isn't, unless it has something to do with "scope" of functions, but in that case why does it work the first time? I've tried debugging the code with firebug, but it can't really help with timeout functions like this. Neither Firefox nor IE8 show any error messages. I've looked through the various posts here and elsewhere on setInterval, but can't see anything relevant that I haven't tried already. I've been experimenting now for about 3 hours and it's doing my head in. Can anyone suggest what I can try next? Thanks in advance Neil

  • CSS: Horizontal scrolling with overflow-x

    - by ams
    Hello fellow programmers, I was wondering if there still isn't a good way to get a div to stretch and scroll horizontally, according to the images inside. -After all, it is 2011 now! The mega-width does the trick, but leaves an empty mega-space if not filled with images. If filled too much, images don't display. Same for the jQuery. The situation below is the best I can do after hours of Googling, but it isn't reliable enough. Thanks for your time. Ams * { margin:0; padding:0; } #one { width:200px; height:250px; overflow-x:auto; overflow-y:hidden; } #two { width:10000em; } #two img { float:left; } $(document).ready(function(){ var total=0; $(".calc").each(function(){ total += $(this).outerWidth(true); }); $("#two").css('width',total); alert(total); }); <div id="one"> <div id="two"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> </div> </div>

  • I can't get datepicker to work

    - by vikitor
    Hi, I need a field that displays the datepicker. I followed the example given by the JQuery UI documentation and haven't managed to get it to work. My html where I have my text field is: <div class="editor-field"> <input type = "text" name = "DatePublished" id = "Published" /> <%= Html.ValidationMessage("DatePublished" ,"*") %> </div> This HTML is in a partial view, lets call it pv.ascx, and it is called in the main page as a modal box: <div id = "ModalBox"> <% Html.RenderAction("pv", "Example"); %> </div> The thing is, that I try to call the datepicker creation anytime I enter the main page, and I do it in my javascript file app.js: $().ready(function() { var place = window.location.pathname; var placesplit = place.split("/"); //Depending on the location we are on, we execute different subroutines $('#Published').datepicker(); }); But nothing happens when I focus on the text field. What is wrong? Could it be that being called from a partial view it doesn't work? Thank you everyone, vikitor

  • Trouble Shoot JavaScript Function in IE

    - by CreativeNotice
    So this function works fine in geko and webkit browsers, but not IE7. I've busted my brain trying to spot the issue. Anything stick out for you? Basic premise is you pass in a data object (in this case a response from jQuery's $.getJSON) we check for a response code, set the notification's class, append a layer and show it to the user. Then reverse the process after a time limit. function userNotice(data){ // change class based on error code returned var myClass = ''; if(data.code == 200){ myClass='success'; } else if(data.code == 400){ myClass='error'; } else{ myClass='notice'; } // create message html, add to DOM, FadeIn var myNotice = '<div id="notice" class="ajaxMsg '+myClass+'">'+data.msg+'</div>'; $("body").append(myNotice); $("#notice").fadeIn('fast'); // fadeout and remove from DOM after delay var t = setTimeout(function(){ $("#notice").fadeOut('slow',function(){ $(this).remove(); }); },5000); }

  • Use of clone() and appendTo() with draggable - unexpected results with dragging

    - by Matt Gutting
    I'm constructing a UI for a doctor scheduling app. We have several doctors, each of whom can go in one of several locations on a scheduled day (M - F). I have the main day/location grid (table) in the center of the screen. At the left is a table for the doctor names. On loading, each table cell contains a span (outlined) with the doctor name. The doctor name can go in one slot for each day. I didn't want to just put 5 copies of the doctor name, because the doctor might not be available all 5 days of the week. The idea was: Drag the span and drop into the calendar table. On the drag "start" event, clone the span and append it to the table cell. Now there is another span ready to be dropped into the calendar table. One line of code does the work: $(ui.helper).clone(true).prependTo(ui.helper.parent()); This works. But when I move the cloned span, the original one moves in sync - preserving the spatial relationships as I move the clone around (no doubt there's a "position:relative;left=XX;top=YY" inserted somewhere). I'm sure there's a way to do what I'm thinking of, while keeping the two spans independent. But I'm not thinking of one. Does anyone have an idea? Thanks! Matt I posted this identical question to the jQuery forum as well.

  • Returned JSON from Twitter and displaying tweets using FlexSlider

    - by Trey Copeland
    After sending a request to the Twitter API using geocode, I'm getting back a json response with a list of tweets. I then that into a php array using json_decode() and use a foreach loop to output what I need. I'm using flex slider to show the tweets in a vertical fashion after wrapping them in a list. So what I want is for it to only show 10 tweets at a time and scroll through them infinitely like an escalator. Here's my loop to output the tweets: foreach ($tweets["results"] as $result) { $str = preg_replace('/[^\00-\255]+/u', '', $result["text"]); echo '<ul class="slides">'; echo '<li><a href="http://twitter.com/' . $result["from_user"] . '"><img src=' . $result["profile_image_url"] . '></a>' . $str . '</li><br /><br />'; echo '</ul>'; } My jQuery looks like this as of right now as I'm trying to play around with things: $(window).load(function() { $('.flexslider').flexslider({ slideDirection: "vertical", start: function(slider) { //$('.flexslider .slides > li gt(10)').hide(); }, after: function(slider) { // current.sl } }); }); Non-Working demo here - http://macklabmedia.com/tweet/

  • Nested asynchronous calls do not seem to execute as expected

    - by Kristof Van Landschoot
    While trying out jQuery, I have a question that is probably a newbie mistake, but I cannot seem to find the solution. This is the code: $.get("index.html", function() { var i = 0; for (; i < 3; i++) { var lDiv = document.createElement('div'); lDiv.id = 'body-' + i; document.getElementById('body').appendChild(lDiv); $.get('index.html', function(data) { lDiv.innerHTML = "<p>Hello World " + i + "</p>"; }); } }); The output seems to be <div id='body-0'></div> <div id='body-1'></div> <div id='body-2'> <p>Hello World 3</p> </div> I expected the lDiv.innerHTML= code to be executed for each i, but apparently it is only executed for the last i? What am I overlooking?

  • Why do child elements cause 'dropleave' to be called (drag-n-drop file upload)?

    - by tundoopani
    I have a HTML5 drag-n-drop script that allows users to drop files in #droparea. The #droparea div has child elements that are also div elements. <div id="droparea"> <div id="showif_no_dragover">Drag files here!</div> <div id="showif_dragover">Drop the files!</div> </div> The associated javascript/jquery is: var droptarget = "#droparea"; $(droptarget).live('dragenter', dragEnter); $(droptarget).live('dragleave', dragExit); $(droptarget).live('dragover', nothing); $(droptarget).live('drop', dropGo); (Side question: should I use .live(), .on() or .bind() here?) I have created a sample jsFiddle with some additional code here: http://jsfiddle.net/PwFr9/3/ If you look at the console, you will notice that as you drag a file within #droparea, dragenter() and dragleave() are called multiple times, even though the drag is still inside #droparea. If you remove the child elements (#child1 and #child2), the problem is gone because the child elements are gone. How can I keep the child elements and prevent them from messing up the drag events? I have searched Stackoverflow and Google for hours without much help. I found this questions here at Stackoverflow: How to keep child elements from interfering with HTML5 dragover and drop events? I don't know why it works, though. I have tried placing 2 div elements on top of each other (via CSS positioning). The top-most div has the drag events attached whereas the bottom-most div has the child elements. I do not like this approach because it doesn't work with the rest of my page and does not allow mouse-click interaction with the bottom-most div. Any help is appreciated! Thank you in advance. Regards, tundoo

  • calling .ajax() from an eventHandler c# asp.ent

    - by ibininja
    Good day...! In the code behind (upload.aspx) I have an event that returns the number of bytes being streamed; and as I debug it, it works fine. I wanted to reflect the numbers returned from the eventHandler on a progress bar and this is where I got lost. I tried using jQuery's .ajax() function. this is how I implemented it: In the EventHandler in my code behind I added this code to call the .ajax() function: Page.ClientScript.RegisterStartupScript(this.GetType(), "UpdateProgress", "<script type='text/javascript'>updateProgress();</script>"); My plan is whenever the eventHandler function changes the values of bytes being streamed it calls the javascript function "updateProgress()" The .ajax() function "UpdateProgress()" is as: function updateProgress() { $.ajax({ type: "POST", url: "upload.aspx/GetData", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", async: true, success: function (msg) { $("#progressbar").progressbar("option", "value", msg.d); } }); } I made sure that the function GetData() is [System.Web.Services.WebMethod] and that it is static as well. so the workflow of what I am trying to implement is as: - Click On Upload button - The Behind code starts executing and EventHandler triggers - The EventHandler calls .ajax() function - The .ajax() function retrieves the bytes being streamed and updates progress bar. When I ran the code; all runs well except that the .ajax() is only executed when upload is finished (and progress bar also updates only when finished upload); even though I call .ajax() function every time in the eventHandler function as reflected above... What am I doing wrong? Am I thinking of this right? is there anything else I should add maybe an updatePanel or something? thank you

  • javascript setTimeout function out of scope.

    - by Keyo
    I am trying to call showUpload(); from within two setTimeouts. Neither works. It seems to be out of scope and I'm not sure why. I tried this.showUpload() which didn't work either. $(document).ready(function(){ var progress_key = $('#progress_key').val(); // this sets up the progress bar $('#uploadform').submit(function() { setTimeout("showUpload()",1500); $("#progressbar").progressbar({ value:0}).fadeIn(); }); // uses ajax to poll the uploadprogress.php page with the id // deserializes the json string, and computes the percentage (integer) // update the jQuery progress bar // sets a timer for the next poll in 750ms function showUpload() { $.get("/myid/videos/uploadprogress/" + progress_key, function(data) { if (!data) return; var response; eval ("response = " + data); if (!response) return; var percentage = Math.floor(100 * parseInt(response['bytes_uploaded']) / parseInt(response['bytes_total'])); $("#progressbar").progressbar({ value:percentage}) }); setTimeout("showUpload()", 750); } }); Thank you for your time.

  • Checking data of all same class elements

    - by Tiffani
    I need the code to check the data-name value of all instances of .account-select. Right now it just checks the first .account-select element and not any subsequent ones. The function right now is on click of an element such as John Smith, it checks the data-name of the .account-select lis. If the data-names are the same, it does not create a new li with the John Smith data. If no data-names are equal to John Smith, then it adds an li with John Smith. This is the JS-Fiddle I made for it so you can see what I am referring to: http://jsfiddle.net/rsxavior/vDCNy/22/ Any help would be greatly appreciated. This is the Jquery Code I am using right now. $('.account').click(function () { var acc = $(this).data("name"); var sel = $('.account-select').data("name"); if (acc === sel) { } else { $('.account-hidden-li').append('<li class="account-select" data-name="'+ $(this).data("name") +'">' + $(this).data("name") + '<a class="close bcn-close" data-dismiss="alert" href="#">&times;</a></li>'); } }); And the HTML: <ul> <li><a class="account" data-name="All" href="#">All</a></li> <li><a class="account" data-name="John Smith" href="#">John Smith</a></li> </ul> <ul class="account-hidden-li"> <ul>

  • Can I combine two functions into one using Javascript?

    - by Melissa
    I have the following code that I would like to simplify. With javascript and jQuery is there an easy way that I could combine these two functions? Most of the code is the same but I am not sure how I could create a single function that works differently depending on what is clicked. $(document).ready(function () { $('#ListBooks').click(ListBooks); $('#Create').click(Create); }); function Create() { var dataSourceID = $('#DataSourceID').val(); var subjectID = $('#SubjectID').val(); var contentID = $('#ContentID').val(); if (dataSourceID && dataSourceID != '00' && subjectID && subjectID != "00" && contentID && contentID != "00") { var e = encodeURIComponent, arr = ["dataSourceID=" + e(dataSourceID), "subjectID=" + e(subjectID), "contentID=" + e(contentID)]; window.location.href = '/Administration/Books/Create?' + arr.join("&"); } else { alert('Datasource, Subject and Content must be selected.'); } return false; } function ListBooks() { var dataSourceID = $('#DataSourceID').val(); var subjectID = $('#SubjectID').val(); var contentID = $('#ContentID').val(); if (dataSourceID && dataSourceID != '00' && subjectID && subjectID != "00" && contentID && contentID != "00") { var e = encodeURIComponent, arr = ["dataSourceID=" + e(dataSourceID), "subjectID=" + e(subjectID), "contentID=" + e(contentID)]; window.location.href = '/Administration/Books/ListBooks?' + arr.join("&"); } else { alert('Datasource, Subject and Content must be selected.'); } return false; }

  • Dragging a copy of all selected elements from a select box--possible?

    - by Sean
    I have a picklist web interface: a pair of select elements with a pair of buttons (a left-pointing arrow and a right-pointing arrow) between them. Users can move items between the two columns by, eg, selecting one of options in the left column and clicking on the right-pointing arrow. Now I have an enhancement request: someone wants to be able to drag-and-drop items between the two columns instead of clicking a button. The problem with my initial two-select-box setup is that as soon as I click one of the highlighted options to initiate a drag, all of the other selected options are deselected. Using jQuery, I've attached mousedown event handlers to both the select boxes and each individual option that just call preventDefault() on the event object, but this isn't sufficient. On Firefox 3 the clicked-on option loses focus immediately, but all other options are still deseleted, and on IE6 (which I regrettably still have to support) it makes no difference at all. So I thought I could maybe create a reasonable facsimile of a select box using list elements or divs or something. I can create something reasonable-looking that works on Firefox, but on IE6, if I shift-click on an element of my pseudo-select object (in order to select a range of options), IE selects all of the text between where I click and the last place I clicked. Again, I've attached preventDefault-ing mousedown, mouseup, and click handlers to all of the elements involved, but it doesn't help. I've even tried overlaying transparent divs over both my original select boxes and my pseudo-select objects, thinking to intercept mouse clicks and manage the selections manually, but I can't make it work on IE. If I use a select box, I can't prevent clicks from changing the selection, and if I use text that just looks like a select element, I can't prevent it from selecting a range of text on a shift-click. Is there some general solution, or am I just out of luck?

  • Obtaining YouTube video ID in a URL and inputting selected video ID into a URL

    - by Dave
    I've been having trouble in trying to figure this out. What I am trying to do is, obtain the ID of a video from YouTube, and input the 11 character ID into the css of a div of a specific id by using jquery. I know the URL for the thumbnail of any video, but I just need to be able to change the ID to display different video thumbnails. <script> $(document).ready(function() { function(data){ videoID = data.split('www.youtube.com/v/')[1].split('&amp')[0]; $("#304817679").append(videoID); }); $("#304817679").replaceWith("<div id=\"304817679\" style=\"background: url(http://img.youtube.com/vi/"+ $.function(data) +"/0.jpg) no-repeat middle; width: 15px; height: 150px;\"></div>"); }); }); </script> <div id="304817679"> <div style="display: none;"><object width="248" height="222"><param name="movie" value="http://www.youtube.com/v/vy90n2nNRKQ&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1"></param><param name="wmode" value="transparent"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/vy90n2nNRKQ&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1" type="application/x-shockwave-flash" width="248" height="222" allowFullScreen="true" wmode="transparent"></embed></object></div> </div> Trying to explain this better, I want the 11 Character YouTube Video ID from the embedded code, and put it into the URL of the thumbnail (http://img.youtube.com/vi/"+ function(data) +"/0.jpg). Which, would then also replace the original div (div id="304817679"). Am I on the right track with my script? I'm entirely new to this, and I would appreciate some of the help that's offered here.

  • Chord Chart - Skip to key with a click

    - by Juan Gonzales
    I have a chord chart app that basically can transpose a chord chart up and down throughout the keys, but now I would like to expand that app and allow someone to pick a key and automatically go to that key upon a click event using a function in javascript or jquery. Can someone help me figure this out? The logic seems simple enough, but I'm just not sure how to implement it. Here are my current functions that allow the user to transpose up and down... var match; var chords = ['C','C#','D','D#','E','F','F#','G','G#','A','A#','B','C','Db','D','Eb','E','F','Gb','G','Ab','A','Bb','B','C']; var chords2 = ['C','Db','D','Eb','E','F','Gb','G','Ab','A','Bb','B','C','C#','D','D#','E','F','F#','G','G#','A','A#','C']; var chordRegex = /(?:C#|D#|F#|G#|A#|Db|Eb|Gb|Ab|Bb|C|D|E|F|G|A|B)/g; function transposeUp(x) { $('.chord'+x).each(function(){ ///// initializes variables ///// var currentChord = $(this).text(); // gatheres each object var output = ""; var parts = currentChord.split(chordRegex); var index = 0; ///////////////////////////////// while (match = chordRegex.exec(currentChord)){ var chordIndex = chords2.indexOf(match[0]); output += parts[index++] + chords[chordIndex+1]; } output += parts[index]; $(this).text(output); }); } function transposeDown(x){ $('.chord'+x).each(function(){ var currentChord = $(this).text(); // gatheres each object var output = ""; var parts = currentChord.split(chordRegex); var index = 0; while (match = chordRegex.exec(currentChord)){ var chordIndex = chords2.indexOf(match[0],1); //var chordIndex = $.inArray(match[0], chords, -1); output += parts[index++] + chords2[chordIndex-1]; } output += parts[index]; $(this).text(output); }); } Any help is appreciated. Answer will be accepted! Thank You

  • Defining an implementation independent version of the global object in JavaScript

    - by Aadit M Shah
    I'm trying to define the global object in JavaScript in a single line as follows: var global = this.global || this; The above statement is in the global scope. Hence in browsers the this pointer is an alias for the window object. Assuming that it's the first line of JavaScript to be executed in the context of the current web page, the value of global will always be the same as that of the this pointer or the window object. In CommonJS implementations, such as RingoJS and node.js the this pointer points to the current ModuleScope. However, we can access the global object through the property global defined on the ModuleScope. Hence we can access it via the this.global property. Hence this code snippet works in all browsers and in at least RingoJS and node.js, but I have not tested other CommomJS implementations. Thus I would like to know if this code will not yield correct results when run on any other CommonJS implementation, and if so how I may fix it. Eventually, I intend to use it in a lambda expression for my implementation independent JavaScript framework as follows (idea from jQuery): (function (global) { // javascript framework })(this.global || this);

  • multiple redirect??

    - by Ryan Pitts
    Ok, i won't go into the full details (too much to explain) but here is what i am trying to do. I have a button on a webpage (we'll call page-1) that links to a page (we'll call it page-2). This page opens in the same window. However, i need the page (page-2) that opens to open up a new window with another page (we'll call this one page-3) when it loads. So virtually when you click the initial button (on page-1) it will go to a new page (page-2) AND a window will open as well with a different page (page-3). This is where it gets tricky. I need page-2 to automatically redirect back to page-1 after it launches page-3. Is this possible and if so, how?? Could it be a JQuery thing? Please just give some answers...i know this is way crazy and a huge workaround - but this is my last resort for this particular website. I have to do it this way because of the lack of control over some of the code.

  • JS sort works in Firefox but not IE - can't work out why

    - by Max Williams
    I have a line in a javascript function that sort an array of objects based on the order of another array of strings. This is working in firefox but not in IE and i don't know why. Here's what my data looks like going into the sort call. (I'm using an array of three items just to illustrate the point here). //cherry first then the rest in alphabetical order originalData = ['cherry','apple','banana','clementine','nectarine','plum'] //data before sorting - note how clementine is second item - we wan to to to be after apple and banana csub = [ {"value":"cherry","data":["cherry"],"result":"cherry"}, {"value":"clementine","data":["clementine"],"result":"clementine"}, {"value":"apple","data":["apple"],"result":"apple"}, {"value":"banana","data":["banana"],"result":"banana"}, {"value":"nectarine","data":["nectarine"],"result":"nectarine"}, {"value":"plum","data":["plum"],"result":"plum"} ] //after sorting, csub has been rearranged but still isn't right: clementine is before banana csubSorted = [ {"value":"cherry","data":["cherry"],"result":"cherry"}, {"value":"apple","data":["apple"],"result":"apple"}, {"value":"clementine","data":["clementine"],"result":"clementine"}, {"value":"banana","data":["banana"],"result":"banana"}, {"value":"nectarine","data":["nectarine"],"result":"nectarine"}, {"value":"plum","data":["plum"],"result":"plum"} ] Here's the actual sort code: csubSorted = csub.sort(function(a,b){ return (originalData.indexOf(a.value) > originalData.indexOf(b.value)); }); Can anyone see why this wouldn't work? Is the basic javascript sort function not cross-browser compatible? Can i do this a different way (eg with jquery) that would be cross-browser? grateful for any advice - max
