I am looking at allowing users to enter JavaScript to specify some logic in my app. The JavaScript would be entered and displayed in a browser, but it would be saved and validated server-side first. This opens up obvious security implications. Ideally, I would want to only allow a subset of the JavaScript language. Intuitively, an op...
I have a multi-select <asp:listbox> and a button. I want to disable the button unless >= 1 item in the listbox is selected. How can I do this client-side? I can't find some sort of OnSelect callback, only OnSelectedIndexChanged which from googling seems complicated to use for this behavior, possibly impossible. ...

I was fine tuning a page that is heavy on jquery and stumbled across this website: http://www.componenthouse.com/extra/jquery-analysis.html When I click on the "Run Test" button the first time, the numbers are way higher than subsequent clicks. Is this because JS is cached by the browser? Can someone explain how this works internally? ...

My problem is related to using the JQuery Tools Tooltip Plugin (http://flowplayer.org/tools/tooltip.html) on items with tooltips that are refreshed in asp.net UpdatePanel controls. The problem is that after the tooltips have been added, any partial postback from an UpdatePanel will cause the tooltips to stop working in any of the UpdateP...
Does anyone know if, using one Request.HTML call from MooTools, it is possible to somehow update more than one element in a webpage? The current call I have is: var req = new Request.HTML({update: $('content')}).get('../latest_events'); This updates the content div in my page with the "../latest_events" page. Is there a way to updat...

The key thing is, my object needs to contain it's own set of YUI tabs so that I can display multiple instances of my object on the same page and have the tabs control their own object instance. I set it up as follows: var Scheduler = function(divid,startDate,mode){ ...

In the course of doing so I've been trying to get some document/on-ready functionality working with the browser I will be integrating into the platform. That's why I'd previously asked this this question here on SO: javascript-framework-that-primarily-provides...
So I'm working on a little bit of jQuery for a site I'm working on and for some reason when I put single quotes inside double quotes Firefox, in it's eternal glory, changes them to double quotes thus breaking my code. I even tried putting it in an external javascript file even though I'm just prototyping at this point. No good. Wouldn't...
I like the Gmail facility of going to the next message using right click and drag mouse to the right. Can I implement that functionality in someone else's website? For example, can I automatically move to the next question / page on the SO site? ...
Hi, I was wondering if I could do the following: load a html page and set the backgroung color of the body element dynamically with javascript, in this case with a jquery script. If the page elements are loaded before the js executes, then the body color will be white for a second, and then it changes the color. If the js would be load...

Hi Again Masters Of The Web :) Now, I have got a new stupid question, and I am asking to forgive me. I read everywhere about this solution, but didn't find the one that works for me.
