JQuery live or something similar with .change()?

问题

I want to do this: http://docs.jquery.com/Events/live#typefn

Only .live() doesn't support the change event- any ideas for work arounds?

Need to bind a function to some on-the-fly DOM elements, but not until change.

回答1:

Note: jQuery 1.4 now supports the live function for all normal events. It didn't work with IE8 until recently, but I believe this is fixed with jQuery 1.4.2. See this resolved jQuery ticket: IE8 DOES NOT SUPPORT THE CHANGE EVENT WHILE USING LIVE

回答2:

LiveQuery plugin supports all events.

Oh that wasn't so bad, i just wrapped it in a live on click event and it worked just fine.


$("#foo").live("click", function(){
  $('.fu').change(function(){
    blah blah blah
  });
});

Ok, after Funka's comments on my first attempt at answering my own question, I now have this:


$('.foo').change(function test(){
  $(fu).prependTo("#some-div").bind("change", test)
  $(this).unbind("change",test)
};

Which will bind the function to each element as it is created, and unbind it from the one created before it. This solves my problem UI-wise, but I'm obvs novice so am really open to learning if I am missing something again! ;)
