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 use older version of jquery or another way?

Answer 1

Depreciated as of 1.7 and removed as of 1.9. Use on() instead.

http://api.jquery.com/on/

$("#myButton").on("click", function(){
    alert("Clicked");
});

Lots of good info here:

As for Unobtrusive Ajax, you will need to include a version of jQuery prior to v1.9 where live() still exists.

If you are referencing the MS CDN,

http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.unobtrusive-ajax.js http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.unobtrusive-ajax.min.js

then it does not appear that these directly reference jQuery. Simply include the 1.8 version in your code instead of the 1.9 version.
