What’s the difference between .delegate() and .live()?

On a separate note…. it would be nice to know which tags are available to use here in the comments. Thanks again for the vid.

Thanks for this video, I had previously been using .live but will switch to .delegate having seen this. Reading the other comments it looks as if I was not alone in using .live. I think this is probably because .live was introduced in 1.3 and .delegate was introduced in 1.4.

Thanks so much for these great screencasts! Do you know if this will show up in the iTunes feed in the future? The latest one there is the previous screencast (Populate Select Boxes).

Hi Remy, you mentioned that event delegation can helps when the DOM is changing, I agree but in addition event delegation for example can help when you have a big table with a lot of rows and you want to give the user option to change the content in the cell. For this example,event delegation would be great instead of RxC(rows multiplied by columns) events (click event for each cell).

A little tip for the next time - first show how it works,If you know how something works behind the scenes you can use it`s full advantage.

Thanks a lot for the screencasts, Yosy

Thanks for linking to the screencast–that cleared the mud for me and made your tutorial all the more useful. Since watching that and your tutorial I’ve been doing some serious code cleaning.

Ah, thanks for this! I just ran into the same problem some days ago and yes… i solved it with copy and paste. U-uh… now I’m reformed. ;-)

Great tutorial, didn't know about that. My solution had been to define a function which did all of the attaching of listeners and then call that every time the content was reloaded.

Never liked it...

This is great though, thanks!

Hi,

Other way (little more dry, but without the delegate method):

$('#picturescontainer').click(function(e) { var tgt = $(e.target); #get the closest img var _img = tgt.closest('img'); # possible filter here if (img.hasClass('somefilteredclassifwanted')) { # call the load content here... } });

I'm keep using this approach for dynamic content, however i really don´t know what is the performance price.

Cheers

Thanks for the video, really good as usual. I have tended to use .live() in the past. Is this the same? Or rather which situations would you use the two? Thanks.

Sorry didn't see the earlier comments...
