live

问题 I am wondering whether there are any circumstances where it would be better to use .click(function {...}); rather than .live(\'click\', function {...}); ? From what I gather the live option seems to be a better option and I am hence using it in almost all circumstances instead of the plain .click(), especially given a lot of my code is loaded asynchronously. EDIT: Another part to this question. If I\'m asynchoronously loading all the javascript in, .click will still pickup all elements

问题 I\'m using jQuery in my web application. While reading its documentation I read about live() and delegate() .

Please help me to get clear understanding of these methods. Thanks 回答1: .live() requires you run the selector immediately, unless you're using the result it's very wasteful. The event handler here is attached to document , so

问题 This question already has an answer here: jQuery: live() vs delegate() 4 answers I\'ve read some posts here and elsewhere on the web about the differences between live() and delegate() . However I haven\'t found the answer I\'m looking for (if this is a dupe please tell me). I know that the difference between live and delegate is that live cannot be used in a chain.

问题 I recently updated jQuery from 1.8 to 2.1. I suddenly discovered that the .live() stops working. I get the error TypeError: $(...).live is not a function . Is there any method I can use in place of .live() ? 回答1: jQuery .live() has been removed in version 1.9 onwards.
