Comments on: You can only go as fast as the slowest component

I’m going through a similar experience witha large table of checkboxes. I started off coding all of the behaviors in jQuery, then had to add LiveQuery to get more flexibility (rows get added and removed). IE6 didn’t like the big table of checkboxes with dozens of events scattered though out. I changed it all to use event delegation and the speed improved across all browsers except, you guessed it, IE6. I chose to use the change event to bind to but IE6 doesn’t bubble the change event. Now several days later I have it working again using click events. What a pain!

Microsoft needs to fix its browser.

Yes, the more specific, the better. Specifying the tag before the class also helps.

However, it’s sad to note that this is only an issue for IE as all other browsers perform equally fast with the “slow” class selector.

jQuery’s class selector can often suck less if you’re more specific, ie, $(‘#someContainer .someClass’);
