jquery/livequery not working in this particular ca

问题:

Using jquery, all of my other livequery functions work fine, i am getting an error for this particular one...

$("[class*='welcome']").livequery("click", function(e){   etc.......

The error is:

Uncaught TypeError: Object #<Object> has no method 'livequery' 

is it because of the wildcard? or a general jquery error?

Thank you

If what you want to do is

Attach an event handler for all elements which match the current selector, now and in the future

Then this is the appropriate syntax:

$(document).on("click", "[class*='welcome']", function() {
    // do stuff
});

jQuery's live() function used to be the way to go, but it has been deprecated in favor of on() as of jQuery 1.7.
