问题
I am new in AJAX. I have searched a lot on Internet but only got basic AJAX steps. Now I am writing codes using AJAX but a common problem I am facing continuously.
When I place return text in the particular id of HTML page, Javascript effects do not work. CSS works fine but Javascript effects like table sorting, jQuery effects or any other effect does not work. I know I am missing some concept here. But didn't get any effective answer.
Please suggest me what should I do? And what is the concept behind this...
回答1:
The new HTML you're adding to the DOM (page) didn't exist when your jquery ran the first time and bound events to elements on the page. You're probably using $("something").click(...) or .bind("click", ...). Instead of these use the delegate function from jquery. Delegate is generally more flexible and faster than live. For instance you can not stopPropagation in a 'live' binding.
Jquery Delegate
Why Delegate is better than Live
Here is another SO answer that explains the benefits of delegate
回答2:
What's most likely happening is that your events are getting unbound because you update the DOM with new elements. The easiest solution is to use the live method to bind to events : http://api.jquery.com/live/
Or you can simply rebind the events to the elements after insertion to the DOM just as easily.
EDIT
As user kasdega points out, another alternative is to use delegate : http://api.jquery.com/delegate/ Delegate works by using the bound root elements as the context to rebind events to DOM elements that may appear in the future.
