I have a few controls that inherit from ASP.NET buttons and use 'onserverclick'. If the user clicks twice, the button fires two server side events. How can I prevent this? I tried setting "this.disabled='true'" after the click (in the 'onclick' attribute) via javascript, but that blocks the first postback as well. ...
Howdy, I'm building a webapp that contains an IFrame in design mode so my user's can "tart" their content up and paste in content to be displayed on their page. Like the WYSIWYG editor on most blog engines or forums. I'm trying to think of all potential security holes I need to plug, one of which is a user pasting in Javascript: <scr...
I'm having a strange problem. I have to use GetPostBackEventRefence to force a Postback, but it works the first time, after the first postback, the .NET function is not rendered... any ideas? This is what I'm missing after the postback: <script language="javascript" type="text/javascript"> <!-- function __doPostBack(eventTarget, event...
How do you capture the mouse events, move and click over top of a Shockwave Director Object (not flash) in Firefox, via JavaScript. The code works in IE but not in FF. The script works on the document body of both IE and Moz, but mouse events do not fire when mouse is over a shockwave director object embed. Update: function displa...
How does Google manage to properly align the second column (i.e. the ticker name) in the "Get Quotes" search box suggestion dropdown in http://finance.google.com? e.g. if you enter "iii" - the second column is perfectly aligned. It does not use a fixed-width font - so just adding the correct numbers of spaces to the "ticker" will not w...
I have a list of data objects to sort. I want to do something like list.sort(function(item1, item2){ return item1.attr - item2.attr; }) to sort it based on a string attribute of the object. But I found that the minus (-) operator does not work for strings in JavaScript. So how do you do string comparison? ...

I'm working on a Silverlight application where I want to take advantage of the Microsoft ASP.NET AJAX Client library. I'm calling the library using the HTML Bridge that is part of Silverlight 2. Silverlight got great support for passing types between JavaScript and Managed Code, but now I've bumped against a problem. Microsoft ASP.NET A...

On another part of this page there are a set of links which, when clicked, the entire page reloads and looks exactly the same as before except for the chart in the middle of the page.

How can I use the Prototype library and create unobtrusive javascript to inject the onmouseover and onmouseout events to each row, rather than putting the javascript in each table row tag? An answer utilizing the Prototype library (instead of mootools, jQuery, etc) would be most helpful. ...
I'm thinking this might be a quick and easy way to lower the form spam on our site just a little bit. The idea being that (I have read) spammers aren't running with javascript enabled. (Or at least they are accessing your website without running javascript. I.e., they aren't browsing up to it in IE or FF. I can use .asp or .aspx. ...
I'm trying to reduce the form spam on our website. (It's actually pretty recent). I seem to remember reading somewhere that the spammers aren't executing the Javascript on the site. Is that true? And if so, then could you simply check for javascript being disabled and then figure it's likely that it's spam? ...
While cross-site scripting is generally regarded as negative, I've run into several situations where it's necessary. I was recently working within the confines of a very limiting content management system. I needed to include database code within the page, but the hosting server didn't have anything usable available. I set up a couple...

I have table inside a div tab. The table has 40 rows in it and the div's height is set to show 10 rows of that table. CSS's overflow:auto lets me scroll through the 40 rows. All is well there. How can I, with JavaScript cause the table to programatically position to a given row (ie, programmatically scroll the table up or down by row)?...
I was wondering if anyone could point to an Open Source date utility class that is fairly robust. I find myself rolling my own when I want to do a lot of things I take for granted in C# and Java. For instance I did find a decent example of a DateDiff() function that I tore apart and another DatePart() function. Another examples would be ...
