I like jQuery and I was wondering if anyone have used a good plugin or (non-jQuery) JavaScript library that allows for auto-formatting of structured fields like phone numbers or dates. I know of the jquery-ui-datapicker plugin, and not what I am looking for here. You may type in a phone number as 123 which then becomes (123), additiona...

I have a webservice that when called without specifying a callback will return a JSON string using application/json as the content type. When a callback is specified it will wrap the JSON string in a callback function, so it's not really valid JSON anymore. My question is, should I serve it as application/javascript in this case or stil...

Is there any way to create the query parameters for doing a GET request in javascript. Just like in python you have urllib.urlencode() which takes in a dict (or list of two tuples) and creates a string like 'var1=value1&var2=value2' ...
In terms of quick dynamically typed languages, I'm really starting to like Javascript, as I use it a lot for web projects, especially because it uses the same syntax as Actionscript (flash). It would be an ideal language for shell scripting, making it easier to move code from the front and back end of a site, and less of the strange syn...

Hi, I'm trying to build a web page with a number of drop-down select boxes that load their options asynchronously when the box is first opened. This works very well under Firefox, but not under Internet Explorer. Below is a small example of what I'm trying to achieve. Basically, there is a select box (with the id "selectBox"), which ...
I've written a control in C# that overrides the built-in DropDownList control. For this I need a javascript resource included, which I'm including as an embedded resource then adding the WebResource attribute, which works fine. However, I also need to reference a webservice, which I would normally include in the scriptmanager on the p...

I'm trying to implement a pop-up menu based on a click-and-hold, positioned so that a (really) slow click will still trigger the default action, and with the delay set so that a text-selection gesture won't usually trigger the menu. What I can't seem to do is cancel the text-selection in a way that doesn't prevent text-selection in th...

EDIT: One of the answers mentions animation....
