  • using javascript setTimeout to see if div has loaded

    - by Matt
    I'm loading remote data using dynamic script tags and JSON. the remote page that I'm displaying on my website has a div in it that I use to load content into. The problem is the javascript functions do not see the div as the page loads because it is remote data. if I set a timeout of about 300 it usually works and my javascipt can see the div. But sometimes it takes longer and it breaks the javascript. I'm tring this: function load_content() { if(document.getElementById('remote_div')==null) { setTimeout('load_content()', 300); } else { document.getElementById('remote_div').innerHTML = 'Content goes here' } } but it just doesn't seem to work... what is wrong with it?

  • Simple iframe editor and oninput event.

    - by teehoo
    I'm writing a simple editor in an iframe, but having trouble registering the "oninput" event to detect when the user modifies the text field such as pasting in data etc. var txtArea = document.getElementById('txtArea'); txtArea.contentWindow.document.designMode="on"; txtArea.contentWindow.document.open(); txtArea.contentWindow.document.write("body{font-size:13px;}"+data.document+""); txtArea.contentWindow.document.close(); $([txtArea.contentWindow.document]).bind("click", updateCaretPosMouse); //fires $([txtArea.contentWindow.document]).bind("keyup", updateCaretPosKeyboard); //fires $([txtArea.contentWindow.document]).bind("input", textChanged); //doesn't fire If I create a plain old textarea element, and add the "input" event to this, then it works. Do 'input" events not work with iframes WYSIWYG editors?

  • JavaScript data grid for millions of rows

    - by Rudiger
    I need to present millions of rows of data to users in a grid using JavaScript. I don't want the user thinking about viewing finite pieces of data; it should appear that all of the data is available. Rather than downloading all the data at once, small chunks are downloaded as the user comes to them (by scrolling, keying in row numbers, searching). The rows will not be edited through this front end, so read-only answers are acceptable. What JavaScript data grids are best for this kind of seamless paging?

  • Access ASP.NET control using javascript

    - by user3036965
    I have a basic javascript function like this which works as I am able to dynamically change the textbox in a javascript method at runtime. function MyTst(pVal2) { var x = document.getElementById('<%=myImage.ClientID%>'); x.src = "/images/write.gif"; } In the above code I need to be generic. So replace '<%=myImage.ClientID%' with the input param to my method which in this instance is called pVal2 and contains the asp.net server control image id. Can anyone advise on an approach to do this. I've tried lots of things and just cant seem to get it working. Thanks for any advice.

  • ASP.NET client side validation with dataannotations - javascript minimumlength zero

    - by Kordonme
    Hi! I'm doing client side validation on a project I'm working on. Everything works, except for the minimumlength property of the StringLength attribute (it works when submitting and a serverside validation is done): [StringLength(50, MinimumLength = 6)] The javascript generated by Html.EnableClientValication(); is the following: // snip {"FieldName":"User.Password","ReplaceValidationMessageContents":true,"ValidationMessageId":"User_Password_validationMessage","ValidationRules":[{"ErrorMessage":"The field Password must be a string with a minimum length of 6 and a maximum length of 50.","ValidationParameters":{"minimumLength":0,"maximumLength":50},"ValidationType":"stringLength"}]}],"FormId":"form0","ReplaceValidationSummary":false}) The important thing is here: {"minimumLength":0,"maximumLength":50} It produces javascript with the wrong minimumproperty. You guys have a hint? Is this a possible bug?

  • PHP equivalent to JavaScript's string split method

    - by m4k00
    I'm working with this on JavaScript: <script type="text/javascript"> var sURL = "http://itunes.apple.com/us/app/accenture-application-for/id415321306?uo=2&mt=8&uo=2"; splitURL = sURL.split('/'); var appID = splitURL[splitURL.length - 1].match(/[0-9]*[0-9]/)[0]; document.write('<br /><strong>Link Lookup:</strong> <a href="http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/wa/wsLookup?id=' + appID + '&country=es" >Lookup</a><br />'); </script> This script takes the numeric ID and gives me 415321306. So my question is how can I do the same thing but using PHP. Best regards.

  • jQuery live() and stopPropagation() issue

    - by colourandcode
    I know that the live() event handles event bubbling different than all other jQuery events. jQuery recommends using 'return false', but in my case that doesn't work. The issue is: I have a DIV which contains an anchor tag. The DIV is bound using live(). Whenever I click the anchor tag inside this DIV it bubbles and calls the DIV's event. If I bind an event to that A tag which returns false it prevents the link from opening. Neither stopPropagation() or return false work in this case. Are there any other options? Ideally I'd like to keep the live() event around.

  • JavaScript OnClick Handler Not Invoking

    - by potatolicious
    I'm calling a javascript function in an inline onclick like so: <a href="#" onclick="removeAttribute('foo', 'bar');">Some Link</a> When I click on the link, though, nothing happens. I have other links (to other functions) tied to onclicks that work fine elsewhere on the same page. All links to this "removeAttribute" function fail. There are no errors in Firebug, and the onclick event handler is being invoked - but stepping into the removeAttribute function ends up, for some reason, somewhere in jQuery.js. At no point does removeAttribute ever get called. If I do: javascript:removeAttribute('foo', 'bar'); in Firefox's address bar. The function is called successfully. Anyone seen this?

  • Keypress event on inserted span (jQuery)

    - by Coder
    Hi, I've been researching for a long time, and haven't found a possible solution. The problem I have is that I'm trying to attach an event handler to an span element just inserted. So basically the problem is, when a user performs a particular action that I set (clicking a button by example) I call this function: function AppendSpan() { $('#mydiv').append('<span id="someid" contenteditable="true">Some TExt</span>'); //Then I want to handle the keypress event on the inserted span $('#someid').keypress(function(event){//Do something here}); } The problem is that the keypress event is never triggered on the inserted span, I tried with the click event and it works fine, but not the keypress or keydown,keyup events. I also tried with $('span').live("keypress",function(event){//Do something}); but didn't work. Any suggestions would be appreciated, I need this to work only in FF, so no support for IE required.

  • Doing some stuff right before the user exits the page

    - by Mike
    I have seen some questions here regarding what I want to achieve and have based what I have so far on those answer. But there is a slight misbehavior that is still irritating me. What I have is sort of a recovery feature. Whenever you are typing text, the client sends a sync request to the server every 45 seconds. It does 2 things. First, it extends the lease the client has on the record (only one person may edit at one time) for another 60 seconds. Second, it sends the text typed so far to the server in case the server crashes, internet connection fails, etc. In that case, the next time the user enters our application, the user is notified that something has gone wrong and that some text was recovered. Think of Microsoft or OpenOffice recovery whenever they crash! Of course, if the user leaves the page willingly, the user does not need to be notified and as a result, the recovery is deleted. I do that final request via a beforeunload event. Everything went fine until I was asked to make a final adjustment... The same behavior you have here at stack overflow when you exit the editor... a confirm dialogue. This works so far, BUT, the confirm dialogue is shown twice. Here is the code. The event if (local.sync.autosave_textelement) { window.onbeforeunload = exitConfirm; } The function function exitConfirm() { var local = Core; if (confirm('blub?')) { local.sync.autosave_destroy = true; sync(false); return true; } else { return false; } }; Some problem irrelevant clarifications: Core is a global Object that contains a lot of variables that are used everywhere. sync makes an ajax request. The values are based on the values that the Core.sync object contains. The parameter determines if the call should be async (default) or sync. Edit 1 I did try to separate both things (recovery deletion and user confirmation that is) into beforeunload and unload. The problem there was that unload is a bit too late. The user gets informed that there is a recovery even though it is scheduled to be deleted. If you refresh the page 1 second later, the dialogue disappears as the file was deleted by then.

  • Set a specific stylesheet based on session variable in javascript

    - by user2371301
    I have an option for a user to select his/her own theme while logged into the system and this theme is set in a MYSQL Database and called each time the user logs in, this is called by: <?php $_SESSION['SESS_THEME_NAME']; ?> Now, I had this working in a PHP file but I need it to work in Javascript instead unfortunately. And I need some help. I looked at the code using the developers tools on Google Chrome and looks like the above code is not resolving within the javascript file. Which makes sense because you can't access session variables within a javascript file (as I found by searching Google.) The code is basically supposed to set the specific stylesheet based on the value extracted from the MYSQL database. So if the database says Default the script needs to tell the webpage to use the default.css file. And so on and so forth. My attempt at writing this is as follows: var themName="<?php $_SESSION['SESS_THEME_NAME']; ?>"; if (themeName == "Default") { document.write("<link re='stylesheet' type='text/css' href='css/mws-theme.css'>"); }; if (themeName == "Army") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-army.css'>"); }; if (themeName == "Rocky Mountains") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-rocky.css'>"); }; if (themeName == "Chinese Temple") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-chinese.css'>"); }; if (themeName == "Boutique") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-boutique.css'>"); }; if (themeName == "Toxic") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-toxic.css'>"); }; if (themeName == "Aquamarine") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-aquamarine.css'>"); }; Any help once so ever would be awesome and much much appreciated! I am reaching a deadline :/

  • Remote Ajax Call in jQuery .click() function doesn't finish before going to next page.

    - by Clint
    I need to send click information on my website to a third party server using ajax (json). I am using jquery and I added the click event to certain links. In the click event I am making a json request to a remote server with the location of the click (heat map) and some other information. The problem is that the ajax function doesn't fire in time before the default link action happens. Setting async to false doesn't seem to work on remote ajax calls. I have tried preventDefault(), but then I don't know how to run the default action after the successful ajax call. Here is what I want to do: $('a').click(submit_click); function submit_click(e,fireAjax){ e.preventDefault(); cd_$.ajax({ url: jsonUrl, //remote server dataType: 'json', data: jsonData, async: false, success: function(reply){ //Run the default action here if I have to disable the default action }, }); } Any suggestions?

  • Bypassing Javascript form handler

    - by Ben Aston
    We are writing an ASP.NET MVC application. By default, if the client browser has Javascript, the handler for every form on the page is set, by Javascript, to be one that sends the submission down an Ajax "pipe" (progressive enhancement). But, for one form (on a page of several), I'd like this handler to be bypassed/ignored. Is there a simple way to do this? Perhaps by overriding the handler by specifying my own onsubmit event directly in the DOM - or some other method? We use jQuery, so those libraries are available to me.

  • Setting asp:Image URL using Javascript function

    - by Anil
    Hi all I have a series of asp:ImageButtons and one asp:Image(Big). Clicking on each ImageButton should change the ImageUrl of asp:Image to a new ImageUrl. How can we handle this using one Javascript function. Because I dont wanna code ImageButton_Click for each and every asp:ImageButton. This makes my application run very slow and also pass too many server requests. Any ideas ????How to design one powerful Javascript function. By the way when the user clicks on ImageButton...the ImageUrl that has to be set to asp:Image(Big) is same as that of ImageButton. This might help a bit. Thanks in advance

  • ASP.NET JavaScript File Embeded In DLL With GZIP

    - by Lee Hesselden
    We have several fairly large JavaScript files embedded into a single script resources DLL. This is then consumed by multiple projects by way of a reference and page includes via the ASP.NET script manager. This keeps things nice and neat within our ASP.NET pages and requires very little work to integrate into new projects. The problem is that some of these script files are quite larger (approx 100KB) and take time to download. By running minify on them before embedding this is reduced down a lot (around 70KB) but not enough. What we would like to do is GZIP the files before they are embedded. However, just gzipping the files causes syntax errors as the content is not unzipped. There is a content type "text/javascript" applied in AssemblyInfo when the resource is embedded but we can't find a way to specify content-encoding. Is there any way to make this work without having to write a httpmodule/handler (which would mean changing the config for all consuming projects)?

  • Mirror a website with httrack while executing javascript

    - by Martin
    I want do save a mirror of www.youtube.com/tv. I obviously do not want to save the videos. I want the code running the website in a local copy, everything else can stay remote. The code I want is mainly contained in 2 files: live.js and app-prod.js. I tried using httrack. I have issue parsing the javascript to load anything past the first file: live.js. The %P parameter does not help. httrack www.youtube.com/tv +* -r6 --mirror -%P -j It doesn't go further than live.js because some javascript needs to be executed to load the next file. I know I can do this manually with any browser. I want to automate the process. Is httrack able to do this by itself? If yes, how?

  • Sharing variable within different javascript file at client side

    - by Aman
    I was actually going through this link. which explains how we can share global variable across multiple js. but the point is what need to be done if I am getting some variable into one js and need to pass to another one mentioned in same document after the 1st one. approach which followed was: Script 1 <script type="text/javascript" src="js/client.js"></script> body added some hidden input with id myHiddenId, where values are set using client.js Script 2 <script type="text/javascript" src="js/anotherJS.js"></script> inside script 2 I am simply using $("#myHiddenId").val(); and using for my purpose. I want to know whether I am following correct approach, because that hidden field may have some data which client should not get aware of. is there any other way through which I can pass the variable values across the js files ? Since I am at beginner level hence digging up some resources/books but still no luck.

  • Visual Studio 2008 Unresponsive When Opening JavaScript Files

    - by lush
    I'm starting a new ASP.NET project that I'm trying to use some jQuery with, but whenever I try to open .js file (blank or containing a few lines of javascript) in Visual Studio, it often hangs; showing the .js filename in a new tab, but the actual text editor window showing whatever was drawn to the screen before opening the .js file. Eventually, after closing and re-opening, it will open in the text editor, but the font is always something like 10pt Arial. Even after changing this in VS options, the next re-launch of Visual Studio yields the same results. Has anyone else experienced hang, unresponsiveness, wonkiness from Visual Studio with JavaScript files?

  • [IE 7/8] Loading HTML content in via Javascript nulls my <title> tag in some instances

    - by Simon
    This is an Explorer only problem and the symptoms are: I have links that when clicked will load in HTML chunks (none of which contain html header tags) using javascript. The html chunks are placed in various <div>s around the page, perhaps 3 different places with 3 different chunks brought in via javascript. When these chunks load in the <title> tag of the page gets set to <title></title> for some unknown (to me) reason. I've used the IE developer toolbar to confirm this by inspecting the DOM tree. I have other pages that do similar things but it does not seem to be a problem there.

  • Why is Javascript's Math.floor the slowest way to calculate floor in Javascript?

    - by z5h
    I'm generally not a fan of microbenchmarks. But this one has a very interesting result. http://ernestdelgado.com/archive/benchmark-on-the-floor/ It suggests that Math.floor is the SLOWEST way to calculate floor in Javascript. ~~n, n|n, n&n all being faster. This seems pretty shocking as I would expect that people implementing Javascript in today's modern browsers would be some pretty smart people. Does floor do something important that the other methods fail to do? Is there any reason to use it?
