Josh... That's not true. Everything I've read says that the less specific you are, the faster your code will run.
In your example, it has to search through a whole bunch of stuff rather than just going and finding items with a class of oldUsers. andy -----Original Message----- From: Josh Nathanson [mailto:[email protected]] Sent: Friday, November 13, 2009 12:20 PM To: cf-talk Subject: RE: 'Tis a sad, sad day...jQuery kills FireFox but works great in IE! You might get a tad bit more speed if you do this in your selectors: $("table.stripe>tbody>tr.oldUsers") Instead of this: $(".oldUsers") This is because jQuery will execute the DOM search more specifically instead of having to traverse the whole DOM for that class. -- Josh -----Original Message----- From: Eric Cobb [mailto:[email protected]] Sent: Friday, November 13, 2009 6:26 AM To: cf-talk Subject: Re: 'Tis a sad, sad day...jQuery kills FireFox but works great in IE! Yeah, after tinkering with it a little more I realized what I was trying to do would be better with classes instead of IDs. I really didn't want to have to deal with a unique ID for all 500 rows. Anyway, here's my jQuery now: $("#userFilter").click(function(){ // If checked if ($("#userFilter").is(":checked")){ //hide all old users $(".oldUsers").css("display","none"); } else { //show all old users $(".oldUsers").css("display","table-row"); } }); It works correctly in both FF and IE, although in FF there's still a good bit of lag time from when you click the checkbox until it actually hides the rows. I guess it's just the way FF is dealing with so many table rows. -- Thanks, Eric Cobb http://www.cfgears.com Peter Boughton wrote: >> I have a (large) table that has a list of >> users with IDs of "newUsers" and "oldUsers". >> > > This is wrong! > > Every ID on the page *must* be unique. > > Use CLASS for common attributes. > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Want to reach the ColdFusion community with something they want?
