Why am I getting this JS error?

Question

I get this JS error:

jquery-1.5.1.min.js:16Uncaught TypeError: Cannot set property \'_renderItem\' of undefined
d.d.extend._Deferred.f.resolveWithjquery-1.5.         


        

Answer 1

I think .data("autocomplete") isn't returning an object, as the error says:

Cannot set property '_renderItem' of undefined

If you are doing this:

$('.foo').data("autocomplete")._render...;

You try breaking it up:

$('.foo').data("autocomplete");
$('.foo')._renderItem = ...;

I've never encountered _renderItem, so I'll look more in to that.

Actually, this question seems to explain a problem really similar to your's: Using _renderItem kind of breaks autocomplete field
