Does anyone know the code fogbugz uses for styling their selects? I'm interested in getting some firefox functionality (when a fixed select width is set for the select, the options width show up expanded to fit long option values). It looks like fogbugz is using a select still, but they've added in an input that shows the current val...

Hello I am creating a web app that uses Rails built in helper functions to add ajax functionality to the site. I do not want the user to be able to use the app without JS as it will not function properly. I need to be able to prevent this.

I am dealing with a content editable div and I need to deal with capturing key strokes both before and after the character has been added to the div. My understanding of capturing vs. bubbling is that the event gets captured at the highest level in the dom tree first then passes it down, while for bubbling it starts at the lowest level ...
Since I use jQuery 1.3+ all except one timed test is using that. The other is plain javascript I found from back in 2000. I stopped going that route as it was taking around 150 seconds to run the test. I've read quite a few jQuery optimization web pages that relate to selecting a single element. A '#id' is the best case for using tha...

If it does so, the shorter domain is used for subsequent origin checks. For example, assume a script in the document at http://store.company.com...

Does anyone use deferred execution of JavaScript or is it something from the past? (I don't see it used on major websites). Also, what are the pros and cons of placing your javascript in the head tag vs placing it in the body? Thanks ...

I'm developing an ASP.NET MVC application in which I want to encrypt a short string on the server, using C#, and send it to the client-side. Then on the client-side it will be decrypted through Javascript code. Any thoughts on how to implement this? Do you know of a simple encryption algorithm (doesn't have to be bullet-proof secure) ...

When adding events, it appears as though they get pushed to the back of a queue, whereas I really ne...

What I'm trying to do is to create a table pager control using jQuery. It contains lots of links and spans. I've managed to do this with plain string concatenation, but I can't believe that jQuery can't make this more elegant. I can't use jTemplates here since the generation has quite a bit of procedural logic. Question: is there a way ...
