How can I make this link clickable in JQuery UI Au

问题:

I'm trying to use the Jquery UI autocomplete plugin, and i'd like to render some html in the suggest box, with clickable links. The html seems to render ok, however when I click the links, they don't work and I get in my developer log:

jquery-ui.min.js:239Uncaught TypeError: Cannot call method 'data' of null

Uncaught TypeError: Cannot call method 'data' of null
a.widget._create.menu.a.addClass.appendTo.mousedown.menu.selectedjquery-ui.min.js:239

a.widget._createjquery-ui.min.js:247
f.event.handlejquery.min.js:17
f.event.add.k.i.handle.k jquery.min.js:16

I'm using the following code in the HTML and Jquery side, the syntax is Haml as its in Rails. In the first script tag, I just define a template that I then render with Underscore.js.

This question seems to reference a similar problem, but I don't understand the answer "I think autocomplete uses an <a> for the element that provides the click event. In that case, you'll need to unset that click handler"

I'd appreciate any guidance! Its been 2 days I've been stuck on this. Thanks!

Im guessing that you have already found a solution for it, but better late then never.

I know this isn´t the optimal solution, but it works.

$(".yourLink").live('click', function () {
    var yourLinkHref= $(this).attr('href');
    window.location = yourLinkHref;

});

Hope it helps :)

I can find no evidence that this is doable without monkey patching a large part of jquery. YUI3 works spectaculary well, however. No monkeying around necessary
