Good Sunday morning! After fiddling around with some JavaScript this weekend, I finally wrote my first script. It is a Tooltip generator. It works great in FF 3 + 3.5, IE 6 + 7, Safari 4, Chrome 2 + 3, and Opera 9 + 10. Before putting my new code into production, I thought I'd ask if you see any glaring problems -- or maybe it's perfec...
I've been building an application with php/mysql and javascript with Prototype/Scriptaculous. A page has a search contacts field, with a default set of data in an HTML table. A user types in some characters, and the table get updated. What's actually happening is the table is getting replaced with a new table and new data. I've got a ...
Using jQuery (and UI), I want to be able to drag table rows out of the table and drop them on some element. The rows themselves should not leave the table, similar to how iTunes works when dragging multiple selected songs. I need to use a table since this is tabular data and I already have a table sort plugin in place. Any idea how to ...
I've been doing some reading about two (relatively) new concepts in the Javascript language - Web Workers and John Resig's awesome Processing.js (well, not really a new 'Javascript concept', but you get my idea). Some great examples of both wander the internets, but I have yet to find one that employs both techniques effectively. It look...

I have a table, and I'm allowing users to 'select' multiple rows. This is all handled using jQuery events and some CSS to visually and data-wise indicate the row is 'selected'. When the user presses shift, it is possible to select multiple rows. However, sometimes this cause text to become highlighted. Is there anyway to programmatically...
Hello, I'm still kindof new to jQuery, so there probably is an easy solution, but I can't find anything. I've made this registration form, that checks if the username or email is taken as the user is typing in the username. Basically it just makes a json request that returns true or false depending on if the username / email is already t...

Here I made two objects; one has accessor methods created in the constructor, the other in the prototype. Why would one choose one of these over the other? function spy1(name){ this.name = name; var secret; this.setSecret = function(message){ secret = message; }; this.getSecret = function(){ return secret; }; } funct...

However, inside of textareas in those forms I want enter key to emit the normal CR-LF pair (because that's what users expect). At the moment assuming I have a form/input structure as follows: <form id="f1"> <fieldset> <input> <textarea i...

There are several good Javascript editors for Markdown / Textile (e.g.: http://attacklab.net/showdown/, the one I'm using right now), but all I need is a Javascript function that converts a string from Markdown / Textile -> HTML and back. What's the best way to do this? (Ideally it would be jQuery-friendly -- e.g., $("#editor").markdown...
My application requires heavy use of ranges (https://developer.mozilla.org/en/DOM/range). In particular, users frequently highlight text and then manipulate it. Sometimes users accidentally highlight text that includes a fragment of a word, and this produces weird results. I'd like to be able to, given a range, check to see whether it s...

Of course, some savvy users of Firefox have the IE tabs ex...
