  • jQuery tablesorter sorting not working

    - by jknox
    I'm using jQuery tablesorter plugin to generate dynamically a table from a csv file, and that part is working fine. However whenever i try to sort the table by clicking on the table headers, firebug reports this problem in the console: parsers is undefined return parsers[i].type;\n Initially i though this problem was being caused by the table not being ready after the document loads, so i fixed that by manually calling tablesorter() after my table was rendered from the csv file. this didn't fix the issue though. Also, at the very end of the table, the table is drawn garbled with some gray areas at the end. I suppose this is related to the error above. The code in question is this: <html> <head> <link rel="stylesheet" href="blue/style.css" type="text/css" /> <script type="text/javascript" src="jquery-1.3.2.min.js"></script> <script type="text/javascript" src="jquery.tablesorter.js"></script> <script type="text/javascript" src="jquery.csv.js"></script> <script type="text/javascript" id="js"> function sortThis() { $("#myTable").tablesorter({ // sortList:[[0,0],[2,1]] }); }; </script> <title>huh!?</title> </head> <body> <table id="myTable" class="tablesorter" cellspacing="1" cellpadding="0" border="0"> <thead> <tr> <th>name</th> <th>type</th> <th>Date</th> </tr> </thead> <tbody> <script type="text/javascript"> $.get('myfile.csv', function(data) { myfile = jQuery.csv()(data) for (var x = 0; x < myfile.length; x++) { str = "<tr>"; for (var y = 0; y < myfile[x].length; y++) { str += "<td>" + myfile[x][y] + "</td>"; } str += "</tr>"; $('#myTable').append(str); } }); sortThis(); </script> </tbody> </table> </body> </html> Thanks in advance for your help.

  • jQuery.load and form elements

    - by Jez
    Is jQuery's .load() supposed to be able to load elements? Because it seems to be stripping them out. So I have some code like: var $dialogContents = $('<div></div>').load($link.attr('href') + ' #divDlgContent', function() { ... } and when the $dialogcontents loads, I return some content with a inside the DIV with the id 'divDlgContent'. Although the rest of the HTML is loaded, the tags are stripped out. Is this by design, and is there a way I can load elements this way?

  • request payload versus query string parameters

    - by Sarah Sides
    I am absolutely in the dark when it comes to this request payload that I'm seeing in my Chrome browser. A Query string will have a variable attached like session:2g0SoEE but this payload has just one long string I'm guessing is in base64. I do understand that the request payload can have whatever, but how do I use it? Can I do a post with jquery and send this request payload? For example: $.post(url, {variable: "variable"}, function(data){}); When this posts it will send &variable=variable this will be found as query string parameter in the headers sent in chrome. In this game I'm playing I see another piece of info being sending in the header called a payload request. I'm a confused as to how this is read, used, made, how I can reduplicate this? Here is something similar: Chrome is caching an HTTP PUT request and How to retrieve Request Payload

  • key-words highlight in <textarea> (again)

    - by Halst
    Wait, I know! I know that this "syntax highlight in textarea"-question was raised like a million times on stackoverflow! But, please, listen. offtopic: I'm not a web-developer, and technically I'm not a programmer at all. I study mechatronics and deal mostly with control-engineering and digital-hardware. And I'm so pissed off that whenever I want to share some application (that would be helpful in my field) and embed it into the web, I need to know such a crazy amount of technologies, like html, css, javascript, flash, etc.. that takes time, which I could have been spending for the benefit of my own field. Right now I'm playing with hardware-description-languages and I'm writing some Python-libraries to convert one HDL into another. And I wanted to embed such feature on the web: http://xhdl2vhdl.appspot.com/ I wanted to implement some basic syntax highlighting (only keywords highlighting will be enough) so that the code could be readable. But the whole idea highlighting something in textarea is not trivial at all. The other difficulty is that the languages I work with are rare, and there are no out-of-box solutions for them. I tried to dig into these solutions, but they are very complicated for me: http://www.nicolarizzo.com/gamesroom/experimental/CodeEditor.html http://marijn.haverbeke.nl/codemirror/jstest.html and there is no clear descriptions how to use them (for my level of knowledge of web-development). So, is there a simple solution, just to highlight a bunch of key-words in textarea or perform something equivalent? Thank you.

  • can javascript process binary data?

    - by Johnny
    admit me describe my questions in situation-oriented way: assume IE is still the dominate web browser(the firefox have document for binary processing): the XMLHttpRequest.responseText or XMLHttpRequest.responseXML in ie desire txt or xml/xhtml/html,but what about the server response the xmlHttprequest whith MIME TYPE application/octet ? would the response string all little than 256 ?(every char of that string < 256), thanks very much for a straight answer, i have no webserver env,so i don't know how to test it out. because use txt or xml have a issue of character set encode, and i don't know how to process #[[[CDDATA node of one encoded xml(ex : utf-8,ascii,gb18030) with javascript, when i getNodeText, does the docObj return me byte or decoded char ? if it was decoded char which according to the header indicated charSet in the httpresponse , it would be all wrong. to avoid mess up with charSet ,i would like the server to response octet data and force strings data to be encoded as utf-8 but another charSet in the binary format. if the response is octal, so i guess the browser would not try to decode the response"txt" does this weird? or miss understanding the fundamental things? EDIT: I believe the question is asking this: Can Javascript safely process strings that aren't encoded in Unicode? What are the problems with trying to do so? EDIT: no no no , i means if http-header: content-type is "application/octet" , would the ie try to decoded it as (16bits Unicode | ie local setting charset ) when i get XMLHttpRequestobj.responseText use javascript ? or it(ie) just wrap every single byte of the response body as a javascript string, then every char in that string little than or equal 256 (char<=256), am i talking Mars language? sadly, if i were Marsizen,i would come as tourist without fuzzy questions. however i am in a country which share at least one property with Mars : RED

  • Best practice for inserting large chunks of HTML into elements with Javscript?

    - by hamstar
    Hey guys. I'm building a web application (using prototype) at the moment that requires the addition of large chunks of HTML into the DOM. Most of these are rows that contain elements with all manner of attributes. Currently I keep a blank row of html in a variable and var blankRow = '<tr><td>' +'<a href="{LINK}" onclick="someFunc(\'{STRING}\');">{WORD}</a>' +'</td></tr>'; function insertRow(o) { newRow = blankRow .sub('{LINK}',o.link) .sub('{STRING}',o.string) .sub('{WORD}',o.word); $('tbodyElem').insert( newRow ); } Now that works all well and dandy, but is it the best practice? I have to update the code in the blankRow when I update code on the page, so the new elements being inserted are the same. It gets sucky when I have like 40 lines of HTML to go in a blankRow and then I have to escape it too. Is there an easier way? I was thinking of urlencoding and then decoding it before insertion but that would still mean a blankRow and lots of escaping. What would be mean would be a eof function a la PHP et al. $blankRow = <<<EOF text text EOF; That would mean no escaping but it would still need a blankRow. What do you do in this situation?

  • jQuery show submit button on input field click

    - by Pjack
    Hi, I'm trying to have a comment input field that will show the submit button on a dynamically created form when you click on the input field. Similar to how facebook comments work. When you click on the input field the submit button appears and when you click off it disappears. All the comment input id's are comment_1 etc and the submit button id's are submit_1 etc. I've tried this, jQuery("#[id^='comment_']").live('click',function(event){ if(jQuery("#[id^='comment_']").val() == ""){ jQuery("#[id^='submit_']").hide(); } else { jQuery("#[id^='submit_']").show(); } }); And that won't work for some reason. Any suggestion or how it can be accomplished would be great.

  • How does Gmail do comet on Opera?

    - by Unknown
    I would like to know how Gmail (or anyone else) does comet on Opera. Here is what I know so far from my experiments. It doesn't use the event-source tag which is broken in Opera 10.51. It doesn't use iframe which displays a spinning throbber and a busy mouse cursor. It doesn't use responseText on xmlhttprequest when readyState = 3 which is known to be broken on Opera. I tried seeing how it was done in mibbit and etherpad, and I found that they both use long-polling.

  • php not redirecting

    - by NSchulze
    I'm trying to write the logout of a website. When I do this I want the page to redirect to the login page. I think I'm doing it the correct way, but can't get the right result. Could you guys point me in the right direction? Relevant Code: <button onclick="logout()">Logout</button> function logout() { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.location=xmlhttp.responseText; } } xmlhttp.open("GET","logout.php",true); xmlhttp.send(); } <?php session_destroy(); header("Location:http://localhost:8888/loginns.html"); mysql_close($con); ?> Thanks!

  • How can I programmatically add triggers to an ASP.NET UpdatePanel?

    - by scottm
    I am trying to write a quote generator. For each product, there are a set of options. I want to dynamically add a drop down list for each option, and then have their SelectedIndexChanged events all wired up to update the quote cost. I am not having any trouble adding the DropDownList controls to my UpdatePanel, but I can't seem to wire up the events. After the page loads, the drop downs are there, with their data, but changing them does not call the SelectedIndexChanged event handler, nor does the QuoteUpdatePanel update. I have something like this: QuotePanel.ASCX <asp:ScriptManager ID="ScriptManager" runat="server" /> <asp:UpdatePanel ID="QuoteUpdatePanel" runat="server" ChildrenAsTriggers="true"> <ContentTemplate> Cost: <asp:Label ID="QuoteCostLabel" runat="server" /> <fieldset id="standard-options"> <legend>Standard Options</legend> <asp:UpdatePanel ID="StandardOptionsUpdatePanel" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional"> <ContentTemplate> </ContentTemplate> </asp:UpdatePanel> </fieldset> </ContentTemplate> </asp:UpdatePanel> The code to add the dropdowns and the event they are to be wire up for: protected void PopluateUpdatePanel(IQuoteProperty standardOptions) foreach (IQuoteProperty standardOp in standardOptions) { QuotePropertyDropDownList<IQuoteProperty> dropDownList = new QuotePropertyDropDownList<IQuoteProperty>(standardOp); dropDownList.SelectedIndexChanged += new EventHandler(QuotePropertyDropDown_SelectedIndexChanged); dropDownList.ID = standardOp.GetType().Name + "DropDownList"; ScriptManager.RegisterAsyncPostBackControl(dropDownList); Label propertyLabel = new Label() {Text = standardOp.Title, CssClass = "quote-property-label"}; this.StandardOptionsUpdatePanel.ContentTemplateContainer.Controls.Add(propertyLabel); this.StandardOptionsUpdatePanel.ContentTemplateContainer.Controls.Add(dropDownList); _standardOptionsListBoxes.Add(dropDownList); AsyncPostBackTrigger trigger = new AsyncPostBackTrigger() { ControlID = dropDownList.UniqueID, EventName = "SelectedIndexChanged" }; this.StandardOptionsUpdatePanel.Triggers.Add(trigger); } } void QuotePropertyDropDown_SelectedIndexChanged(object sender, EventArgs e) { QuoteCostLabel.Text = QuoteCost.ToString(); }

  • How can I implement a "wizard" style page using JQuery?

    - by Mark Brittingham
    I am implementing a questionnaire on the web and I'd like for each block of questions to have its own "page" so the user doesn't have to scroll. However, page loads have two problems: a) they take time (and have a noticeable flicker/refresh) and b) such an approach would force me to do a data table insert plus multiple updates (or store it all in my session). How can I use JQuery to let the user page through the questionnaire on the client side, answering questions as he goes? I'll then be able to handle the data store when all the answers are submitted at the end. One other thing...is there a way to make sure that the session doesn't time out if the user takes awhile?

  • Why can't I roll a loop in Javascript?

    - by Carl Manaster
    I am working on a web page that uses dojo and has a number (6 in my test case, but variable in general) of project widgets on it. I'm invoking dojo.addOnLoad(init), and in my init() function I have these lines: dojo.connect(dijit.byId("project" + 0).InputNode, "onChange", function() {makeMatch(0);}); dojo.connect(dijit.byId("project" + 1).InputNode, "onChange", function() {makeMatch(1);}); dojo.connect(dijit.byId("project" + 2).InputNode, "onChange", function() {makeMatch(2);}); dojo.connect(dijit.byId("project" + 3).InputNode, "onChange", function() {makeMatch(3);}); dojo.connect(dijit.byId("project" + 4).InputNode, "onChange", function() {makeMatch(4);}); dojo.connect(dijit.byId("project" + 5).InputNode, "onChange", function() {makeMatch(5);}); and change events for my project widgets properly invoke the makeMatch function. But if I replace them with a loop: for (var i = 0; i < 6; i++) dojo.connect(dijit.byId("project" + i).InputNode, "onChange", function() {makeMatch(i);}); same makeMatch() function, same init() invocation, same everything else - just rolling my calls up into a loop - the makeMatch function is never called; the objects are not wired. What's going on, and how do I fix it? I've tried using dojo.query, but its behavior is the same as the for loop case.
