Yesterday I gave a small lecture on designing and developing for the Web with IE6 support in mind. The presentation covers some of the most common bugs and techniques to circumvent or altogether avoid those little annoying issues that plague us all. Some of the bugs and their solutions were taken from Chris Coyer’s excellent post at CSS-Tricks on the same subject. Without further ado, here is the presentation:

Ah, CTRL-Z. I’m sure at some point in our lives, everyone has wished they had the ability to go back in time and Undo something they did. The ability to undo, however, is rather commonplace in the computer world. It allows one to revert a document to an older state by negating the last action(s) performed and all of their consequences.

If you have used a computer before, I’m sure this feature has saved you numerous times. It’s so deeply rooted in our subconscious people sometimes use it without even thinking about it. If undo is so successful on the desktop, what is the reason for it’s almost non-existance in Web Applications?

If you’re using jQuery along with another Javascript Framework (such as Prototype) which also implements the $ variable, you can give back control over it to whichever library first implemented it by using the following code (right after including jQuery):

jQuery.noConflict();

Now, instead of using $ to select jQuery objects, you will be able to use jQuery:

var el = jQuery("#myID");

However, typing jQuery every single time you want to select something gets old real quick, so you can use this trick when declaring noConflict():

var $j = jQuery.noConflict();

This reassigns the reference to the jQuery object to whichever variable you want. In this example, you can now use $j instead of jQuery as a selector. You’ll be (at least) 10 times more productive now!
