  • Dynamic table memory usage

    - by Dan
    I use a dynamic table: <html> <body> <button id="button">Build table</button> <div id="container"> <script type="text/javascript"> window.onload=function(){ var table = null; var row = "<tr><td>111111111111111111111111111111111111111111111111111111</td>" + "<td>222222222222222222222222222222222222222222222222222222</td>" + "<td>333333333333333333333333333333333333333333333333333333</td></tr>"; var data = null; for (var i = 0; i < 2000; i++){ data += row; } var obj = document.getElementById("button"); obj.onclick=function buildTable(){ document.getElementById("container").innerHTML = "<div><table><tbody>" + data + "</tbody></table></div>"; }; }; </script> </body> </html> Using chromes task manager, each time new data is loaded the memory usage increases considerably and doesn't go down, so after some time the app consumes a lot of memory and requires the browser to be closed. Is there any change in the code I can use to solve this or is it a browser side problem?

  • How to "push" updates to individual cells in a (ASP.NET) web page table/grid?

    - by dommer
    I'm building something similar to a price comparison site. This will be developed in ASP.NET/WebForms/C#/.NET 3.5. The site will be used by the public, so I have no control over the client side - and the application isn't so central to their lives that they'll go out of their way to make it work. I want to have a table/grid that displays products in rows, vendors in columns, and prices in the cells. Price updates will be arriving (at the server) continuously, and I'd like to "push" any updates to the clients' browsers - ideally only updating what has changed. So, if Vendor A changes their price on Product B, I'd want to immediately update the relevant cell in all the browsers that are viewing this information. I don't want to use any browser plug-ins (e.g. Silverlight). Javascript is fine. What's the best approach to take? Presumably my options are: 1) have the client page continuously poll the server for updates, locate the correct cell and update it; or 2) have the server be able to send updates to all the open browser pages which are listening for these updates. The first one would seem the most plausible, but I don't want to constrain the assembled wisdom of the SO community. I'm happy to purchase any third party components (e.g. a grid) that might help with this. I already have the DevExpress grid/ajax components if they provide anything useful.

  • How to update child iFrame's entire html (header+body) inside jQuery's post

    - by knappy
    I have a chat webpage for Firefox that is structured like this ..... Outer HTML -----|......Frameset Frame ------------|...... header: contains jQuery post has returned data: rdata = new_iFrame_html_str, the entire html string of the iFrame that should be updated ------------|...... iFrame --------------------|...... header: contains jQuery --------------------|...... body: chat messages that depends on the header jQuery to behave properly QUESTION: I can't this jQuery post to work, i.e. I can't find a way for this post to update the ENTIRE iFrame (header + body). Things I've tried and FAILED with javascript and jQuery: top.frames['framesetFrame_name'].document.getElementById('iframe_id').contentDocument.body.innerHTML = new_iFrame_html_str; I don't like this because it's only changing the body, not the header, so the behavior generated from jQuery can't be shown top.frames['framesetFrame_name'].document.getElementById('iframe_bucinid').contentWindow.location.reload(); I do not want to reload because a reload makes the iFrame flicker, bad for a chat program top.frames['framesetFrame_name'].document.getElementById('iframe_id').contents().html = new_iFrame_html_str; Not updating anything that shows :( top.frames['framesetFrame_name'].document.getElementById('iframe_id').contentWindow.location.href = new_iFrame_html_str; This is actually the wrong form here, because it should be = url_of_new_content $( top.frames['framesetFrame_name'].document.getElementById('iframe_id') ).html( new_iFrame_html_str ) ; Not updating anything that shows :(

  • XMLHttpRequest() and outputting csv file

    - by sjw
    Initially, I developed a javascript function to use window.open to post contents of a form to a new window which simply opened the new window and initiated a csv file download. Now on reflection, I find the opening of the window superfluous and am trying to just execute a XMLHttpRequest() to download the csv. I am not getting what I want and I'm not 100% sure that I can so I thought I'd ask here for some assistance. When a form is submitted, I want to take all the form values and post them to another page which builds an SQL string and builds a csv based on the contents. (This I can do and works fine with XMLHttpRequest() as seen below) var xhReq = new XMLHttpRequest(); var parameters = ""; for ( i=0; i<formObj.elements.length; i++ ) { parameters += formObj.elements[i].name + "=" + encodeURI( formObj.elements[i].value ) + "&"; } xhReq.open("POST", outputLocation, false); xhReq.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xhReq.setRequestHeader("Content-length", parameters.length); xhReq.setRequestHeader("Connection", "close"); xhReq.send(parameters); document.write(xhReq.responseText); The code above calls the page ok, builds the csv ok, but it outputs the contents into the current browser window instead of initiating a csv file download. Can I achieve what I need using XMLHttpRequest() or am I going it about it the wrong way? Thanks

  • Form validation

    - by kielie
    Hi guys, I need to create a form that has many of the same fields, that have to be inserted into a database, but the problem I have is that if a user only fills in one or two of the rows, the form will still submit the blank data of the empty fields along with the one or two fields the user has filled in. How can I check for the rows that have not been filled in and leave them out of the query? or check for those that have been filled in and add them to the query. . . The thank_you.php file will capture the $_POST variables and add them to the database. <form method="post" action="thank_you.php"> Name: <input type="text" size="28" name="name1" /> E-mail: <input type="text" size="28" name="email1" /> <br /> Name: <input type="text" size="28" name="name2" /> E-mail: <input type="text" size="28" name="email2" /> <br /> Name: <input type="text" size="28" name="name3" /> E-mail: <input type="text" size="28" name="email3" /> <br /> Name: <input type="text" size="28" name="name4" /> E-mail: <input type="text" size="28" name="email4" /> <input type="image" src="images/btn_s.jpg" /> </form> I am assuming that I could use javascript or jQuery to accomplish this, how would I go about doing this? Thanx in advance for the help.

  • Normals per index?

    - by WarrenFaith
    I have a pyramid which has 5 vertex and 18 indices. As I want to add normals to each face I just found solution for normals for each vertex. That means I can't use indices to define my pyramid I need to have 18 vertex (and 3 times the same vertex for the same point in space). There must be a solution to use normals not on vertex base but on index base. Some code (javascript): var vertices = [ -half, -half, half, // 0 front left half, -half, half, // 1 front right half, -half, -half, // 2 back right -half, -half, -half, // 3 back left 0.0, Math.sqrt((size * size) - (2 * (half * half))) - half, 0.0 // 4 top ]; var vertexNormals = [ // front face normaleFront[0], normaleFront[1], normaleFront[2], normaleFront[0], normaleFront[1], normaleFront[2], normaleFront[0], normaleFront[1], normaleFront[2], // back face normaleBack[0], normaleBack[1], normaleBack[2], normaleBack[0], normaleBack[1], normaleBack[2], normaleBack[0], normaleBack[1], normaleBack[2], // left face normaleLeft[0], normaleLeft[1], normaleLeft[2], normaleLeft[0], normaleLeft[1], normaleLeft[2], normaleLeft[0], normaleLeft[1], normaleLeft[2], // right face normaleRight[0], normaleRight[1], normaleRight[2], normaleRight[0], normaleRight[1], normaleRight[2], normaleRight[0], normaleRight[1], normaleRight[2], // bottom face 0.0, -1.0, 0.0, 0.0, -1.0, 0.0, 0.0, -1.0, 0.0, 0.0, -1.0, 0.0, 0.0, -1.0, 0.0, 0.0, -1.0, 0.0, ]; var pyramidVertexIndices = [ 0, 1, 4, // Front face 2, 3, 4, // Back face 3, 0, 4, // Left face 1, 2, 4, // Right face 0, 1, 2, 2, 3, 0, // Bottom face ];

  • Why is search functionality not working on this page?

    - by DaveDev
    we deliver micro-site content for our client. Our content is injected into a wrapper that is supplied by another developer. To deliver our content we host the wrapper as well as the content. The user can access this at http://fundcentre.newireland.ie/ (try a search for 'bloxham') For the other content that is not ours, the other developer hosts a similar (though slightly different) wrapper and delivers the content. the user accesses this here: http://www.newireland.ie/ (try a search for 'bloxham') The wrapper contains a search box, which does not work for us but it works for the other developer. I took a look at the network traffic with FireBug but it appears that when I do the search from the wrapper that we're hosting, I'm getting a "407 Proxy Access Denied" error. My guess is their proxy has a problem with the fact that the search is being conducted from a page hosted outside the scope of their proxy. It was also suggested that there were javascript errors on the page that were preventing the search from executing but I can't see any. Also, I don't think I'd get as far as the proxy error if that was the case. I don't really understand this stuff too well though, so could somebody with a bit more experience please take a look and maybe shed some light on this for me? Thanks.

  • Generate random number from an arbitrary weighted list

    - by Fernando
    Here's what I need to do, I'll be doing this both in PHP and JavaScript. I have a list of numbers that will range from 1 to 300-500 (I haven't set the limit yet). I will be running a drawing were 10 numbers will be picked at random from the given range. Here's the tricky part: I want some numbers to be less likely to be drawn up. A small set of those 300-500 will be flagged as "lucky numbers". For example, out of 100 drawings, most numbers have equal chances of being drawn, except for a few, that will only be picked once every 30-50 drawings. Basically I need to artificially set the probability of certain numbers to be picked while maintaining an even distribution with the rest of the numbers. The only similar thing I've found so far is this question: Generate A Weighted Random Number, the problem being that my spec has considerably more numbers (up to 500) so the weights would get very small and supposedly this could be a problem with that solution (Rejection Sampling). I'm still trying it, though, but I wonder if there other solutions. Math is not my thing so I appreciate any input. Thanks.

  • Porting a web application to work in IE7

    - by Bears will eat you
    I'm developing a web application that uses lots of Javascript and CSS, both of my own creation and through third-party libraries. These include jQuery and Google Maps & Visualization JS APIs. I've been testing everything in Firefox 3. Things are peachy until it turns out the main target of this webapp is (cue sad trombone) IE7. I'm looking for caveats, advice, libraries, or other references to help make this transition as easy as possible (not that it's actually going to be easy). I've already tried IE7.js though it hasn't yet shown itself to be the silver bullet I was hoping for. I'm sure that it works as advertised, I think it's just not as all-encompassing as I'd like (example: colors like #4684EE and #DC3912, which are correctly rendered in FF3, are rendered as black in IE7, with or without IE7.js). Are there other libraries out there to help bring IE7 (more) in line with FF3? A corollary question: what debugger would you recommend for IE7? I'm currently using Firebug Lite, but it runs painfully slowly. Is there anything out there with similar features that I might have missed?

  • Dynamically add data stored in php to nested json

    - by HoGo
    I am trying to dynamicaly generate data in json for jQuery gantt chart. I know PHP but am totally green with JavaScript. I have read dozen of solutions on how dynamicaly add data to json, and tried few dozens of combinations and nothing. Here is the json format: var data = [{ name: "Sprint 0", desc: "Analysis", values: [{ from: "/Date(1320192000000)/", to: "/Date(1322401600000)/", label: "Requirement Gathering", customClass: "ganttRed" }] },{ name: " ", desc: "Scoping", values: [{ from: "/Date(1322611200000)/", to: "/Date(1323302400000)/", label: "Scoping", customClass: "ganttRed" }] }, <!-- Somoe more data--> }]; now I have all data in php db result. Here it goes: $rows=$db->fetchAllRows($result); $rowsNum=count($rows); And this is how I wanted to create json out of it: var data=''; <?php foreach ($rows as $row){ ?> data['name']="<?php echo $row['name'];?>"; data['desc']="<?php echo $row['desc'];?>"; data['values'] = {"from" : "/Date(<?php echo $row['from'];?>)/", "to" : "/Date(<?php echo $row['to'];?>)/", "label" : "<?php echo $row['label'];?>", "customClass" : "ganttOrange"}; } However this does not work. I have tried without loop and replacing php variables with plain text just to check, but it did not work either. Displays chart without added items. If I add new item by adding it to the list of values, it works. So there is no problem with the Gantt itself or paths. Based on all above I assume the problem is with adding plain data to json. Can anyone please help me to fix it?

  • Linkbutton to open Windows Explorer from Gridview

    - by xt_20
    Hi all, I have a link in a Gridview that I want opened in Windows Explorer (or explorer.exe). <asp:GridView ID="GridView1"runat="server" > <Columns> <asp:TemplateField> <ItemTemplate> <asp:LinkButton ID="DeploymentLocation" runat="server" CommandName="OpenLink" Text='<%# Eval("DeploymentLocation") %>' CommandArgument='<%# Eval("DeploymentLocation") %>' /> </ItemTemplate> </asp:TemplateField> </Columns> and in codebehind I have this: protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) { Process.Start("explorer.exe", "/n," + e.CommandArgument.ToString()); } Obviously this doesn't work as Process.Start only works if I have full permissions, etc, etc. I heard that I can use Javascript to do this, but haven't succeeded so far. Basically, what I want is the exact link that is displayed in the grid to be opened when clicked. Any help would be much appreciated! Thanks!

  • Structuring the UI code of a single-page EXTjs Web app using Rails?

    - by Daniel Beardsley
    I’m in the process of creating a large single-page web-app using ext-js for the UI components with Rails on the backend. I’ve come to good solutions for transferring data using Whorm gem and Rails support of RESTful Resources. What I haven’t come to a conclusion on is how to structure the UI and business logic aspects of the application. I’ve had a look at a few options, including Netzke but haven’t seen anything that I really think fits my needs. How should a web-application that uses ext-js components, layouts, and controls in the browser and Rails on the server best implement UI component re-use, good organization, and maintainability while maintaining a flexible layout design. Specifically I’m looking for best-practice suggestions for structuring the code that creates and configures UI components (many UI config options will be based on user data) Should EXT classes be extended in static JS for often re-used customizations and then instantiated with various configuration options by generated JS within html partials? Should partials create javascript blocks that instantiate EXT components? Should partials call helpers that return ruby hashes for EXT component config which is then dumped to Json? Something else entirely? There are many options and I'd love to hear from people who've been down this road and found some methodology that worked for them.

  • Dynamically resizing navigation div to main content

    - by theZod
    Greetings and Hello I am trying to put together a wordpress site, now because the content in the main div is going to be a different height with every page I need the navigation sidebar to stretch to the same height. So with a little javascript tom-foolery I can get the sidebar to be the same height with the following code function adjust(){ hgt=document.getElementById('content').offsetHeight; document.getElementById('sidebar').style.height=hgt+'px'; } window.onload=adjust; window.onresize=adjust; Now that's all good for a long page but if the content is smaller then the sidebar stuff gets all messy. So I have tried an if statement like so function adjust() { if (document.getElementById('content').style.height < document.getElementById('sidebar').style.height){ hgt=document.getElementById('content').offsetHeight; document.getElementById('sidebar').style.height=hgt+'px'; else hgt=document.getElementById('sidebar').offsetHeight; document.getElementById('content').style.height=hgt+'px'; } } window.onload=adjust; window.onresize=adjust; But that just doesn't do anything, so any ideas whats going on?

  • How to develop Online Shopping Portal Application using PHP ?

    - by Sarang
    I do not know PHP & I have to develop a Shopping Portal with following Definition : Scenario: Online Shopping Portal XYZ.com wants to create an online shopping portal for managing its registered customers and their shopping. The customers need to register themselves first before they do shopping using the shopping portal. However, everyone, whether registered or not, can view the various products along with the prices listed in the portal. The registered customers, after logging in, are allowed to place order for one or more products from the products listed in the portal. Once the order is placed, the customer gets a reference order number and the order status should be “order in process”. The customers can track their order using the given reference number. The management of XYZ.com should be able to modify the order status of a particular reference order number to “shipped” once the products are shipped to the shipping address entered by the customer at the time of placing the order. The Functionalities required are : Create the interface for the XYZ.com shopping portal using HTML/XHTML and CSS. Implement the client side validations using JavaScript. Create the tables using MySQL. Implement the functionality using the server side scripting language, PHP. Integrate all the above tasks and make the XYZ.com shopping portal functional. How do I develop this application with following proper steps of development ?

  • I get NaN when I try to insert some HTML into a DIV element with jQuery

    - by Ankur
    I am tring to display a text box when a element of class numObj is clicked. For some reason I get NaNNaNaNaNNaNNaNaNaN where I expect to the see the result of the searchForm variable in the code below. I know that NaN stands for Not a Number.

  • Is it posible to use "confirmit" to open new url in the same window?

    - by Dan Peschio
    I'm using a the confirmit java script function to redirect to a new url with a positive response. It doesn't do exactly what I want - and maybe I can't have exactly what I want. Here's what it does - onunload, with a positive response it opens the new url in a new window, which can be blocked by a pop-up blocker without the user even knowing, giving the impression that nothing happened. When it does open the new URL it opens in a new window making the desktop crowded. Its just not a great solution. What I want it to do - onunload I'd like it to open the new url in the same window and have it not be classified as a "pop-up" to be blocked. I tried switching to onbeforeunload.... nuthin. Is there a simple solution? here's my current code: <script language=javascript> function confirmit() { var closeit= confirm("My message"); if (closeit == true) {window.open("http://MyDestinationURL");} else {window.close();} } window.onunload = confirmit </script>

  • How do I select dynamic ids in this format?

    - by sjsc
    I'm trying to select dynamic ids when a user types something into the input fields. My app spits out the input fields in the following format: <input id="student_1_first_name" /> <input id="student_1_last_name" /> <input id="student_2_first_name" /> <input id="student_2_last_name" /> <input id="student_3_first_name" /> <input id="student_3_last_name" /> etc. For example, I tried doing this to select the end of the id string: <script type="text/javascript"> $(document).ready( function (){ $("input[id$=_first_name]").bind("keyup", run_some_function_here); run_some_function_here(); $("input[id$=_last_name]").bind("keyup", run_some_function_here); run_some_function_here(); } ); </script> When I do that, Jquery can't seem to select the input ids, so the functions don't run. Do you have any ideas on how I can select the ids correctly?

  • 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.

  • SVG rotation animation having problems on chrome for jelly bean, is there a workaround?

    - by Metalskin
    I've got a strange problem with chrome on jellybean running svg animations triggered from javascript. This JSFiddle example works fine on chrome and firefox on linux, but when I run it on android with chrome I get the final step of the animation painted at the beginning of the animation. I've tried this on both an Nexus 7 and Transformer Prime, they both have the problem. I've tested using firefox on the android devices and the problem doesn't exist. So I'm presuming that it's a defect with chrome. However I've seen other animations using svg that do not have this problem in chrome on jellybean. Is anyone aware of a way to get around this problem, or is there something that I'm doing in my animation/js that is a possible cause of the problem? I've now created a bug report at code.google.com, however I still need a workaround, if anyone can help me (or in case I'm doing something stupid). I've now discovered that this is reproducible on chrome for linux (and I suspect windows). If you click on the button to start the animation before the previous animation has completed then the problem occurs. In this case the hand is drawn at the end of the 45 degree sweep before it starts the sweep. I now suspect that I should be calling something to stop the animation before I change the animation. Anyway, hopefully someone can resolve this problem.

  • jQuery Form Validation being bypassed

    - by user1953681
    Can someone tell me what is wrong with my jQuery validation? It is not validating my form, rather, just ignoring the code resulting in no check of the inputs. Form: <form class="form" accept-charset="UTF-8" action="URL-to-complete-form" method="POST" onsubmit="return validateForm();"> <input class="form-name" type="text" placeholder="Name"></div> <input class="form-email" type="text"placeholder="Email"></div> <input style="background-color: #fc8f12;" type="submit" value="Subscribe"> </div> </form> Javascript: function validateForm() { // Validate Name var title = $(".form-name").val(); if (title=="" ||title=="Name" || title==null) { } else { alert("Please enter a name!"); } // Validate Email var email = $(".form-email").val(); if ((/(.+)@(.+){2,}\.(.+){2,}/.test(email)) || email=="" || email=="Email" || email==null) { } else { alert("Please enter a valid email"); } return false; } Thank you all for your time and help.

  • Need help getting Wysihat to work

    - by slythic
    Hi all, I'm using Wysihat in a rails project and am stumped by it's inability to bind to my textarea named post_description (model name Post field name description). I have the following in my head tag: <%= javascript_include_tag 'prototype_1.7'%> <%= javascript_include_tag 'wysihat' %> <script type="text/javascript" charset="utf-8"> document.on("dom:loaded", function() { var editor = WysiHat.Editor.attach('post_description'); var toolbar = new WysiHat.Toolbar(editor); toolbar.addButtonSet(WysiHat.Toolbar.ButtonSets.Basic); // Hide our error message if the editor loads fine $('error').hide(); }); </script> I'm able to see Wysihat works (the bold, italic, and underline tools are shown and when click works as intended). The following in the source of the posts/new HTML: <div id="post_description_editor" class="editor" contenteditable="true"></div> <textarea cols="40" id="post_description" name="post[description]" rows="20" style="display: none; "></textarea> However, when I type something in the description field and click submit the post validation fails saying the description field is empty. Anyone have any clue on how I can get this to work? Thanks in advance!

  • Firefox extension js object initialization

    - by Michael
    Note: this is about Firefox extension, not a js general question. In Firefox extension project I need my javascript object to be initialized just once per Firefox window. Otherwise each time I open my window a new timers will be engaged, new properties will be used, so everything will start from scratch. hope example below will demystify my question :) var StupidExtension { statusBarValue: "Not Initialized Yet", startup: function () { ... // Show statusBarValue in Status Bar Panel }, initTimerToRetrieveStatusBarValueFromNetwork: function () { ... } } so each time you hit Ctrl+N a new window you will see "Not Initialized Yet" and then new timer will be fired, so after some time it retrieve data from network you will see value also on second window and so on. Ideally would be to have just a single timer function running and updating all status bar panels in all Firefox windows. Of course I can do some caching, like saving the value in prefs or some other storage, then show it from there. But I feel like this is artificial. So the question will be is there "native" technique of making static some parts of the object among all Firefox window instances?
