data() can only read Data Attribute objects in single quotes

[p_gasston@…]

When using data() to get objects from a Data Attribute, the attribute must be within single quotes:

<div data-example='{"foo":"bar"}'>

It's much more common to use double quotes for attributes, so the following should also be valid:

<div data-example="{'foo':'bar'}">

This is not currently recognized by jQuery.

Replying to p_gasston@…:

so the following should also be valid: <div data-example="{'foo':'bar'}">

This isn't a jQuery bug. The reason this doesn't work is the value of data-example looks like JSON but actually is invalid. JSON requires you to use double quotes (check ​http://www.json.org/).
