jquery live hover

Question

I'm using the following jquery code to show a contextual delete button only for table rows we are hovering with our mouse. This works but not for rows that have been added with js/ajax on the fly...

Is there a way to make this work with live events?

$("table tr").hover(
  function () {},
  function () {}
);

Answer 1

jQuery 1.4.1 now supports "hover" for live() events, but only with one event handler function:

$("table tr").live("hover",

function () {

});

Alternatively, you can provide two functions, one for mouseenter and one for mouseleave:

$("table tr").live({
    mouseenter: function () {

    },
    mouseleave: function () {

    }
});
