#7524 closed bug (fixed)

Calling $.fn.data without arguments on a non-DOMelement in 1.4.4

Reported by: timmolendijk Owned by: snover
Priority: blocker Milestone: 1.5
Component: data Version: 1.4.4
Keywords: regression Cc:
Blocked by: Blocking:

Description

Try the following code in 1.4.3 and then in 1.4.4:

$({tim: 28}).data()

In 1.4.3 the expected data object is returned, in 1.4.4 a TypeError in thrown: "Cannot read property 'length' of undefined"

The problem is in line 1250, in which it is assumed that the data object has an "attributes" property (which is obviously a valid assumption for DOM nodes with nodeType 1 but not for many other object types).

Here's a simple jsFiddle for this use case http://jsfiddle.net/boushley/CCdtM/.

Calling $.fn.data on a plain JS object with no argument will just return the JS object. Is there actually a use case here?

Use case; sometimes it's a custom (not necessarily plain) JS object, sometimes it's a DOM element. That's where the $.data API shines, as you can just treat them all the same. This bug messes up this unity.

I wish, I wish, I wish this wasn’t a regression.
