jquery 1.9.0 live function?

Question

There is no live() function in jquery 1.9.0, but jquery.unobtrusive.ajax.js is already use this function.

Should I us

Answer 1

.live() has been replaced with the event delegation syntax of .on():

$('#parent').on('click', '.child', function() {
  ...
});

#parent should exist when you call your selector, so if your element is top-level, use document as the parent.
