.data() doesn't parse JSON strings, but accepts all other JSON notation

Regarding the broken .data() functionality in jQuery 1.4.3

It is expected that .data() can be used to pass a JSON encoded variable into a data attribute and having it fetched in the same structure with .data() by the client. This is true for null, boolean, number, array and object but not strings!

What I expect: To retain the structure, variables & types of the data.

What actually happens: Strings are either unparsed or accidentally parsed as something else. There is no functionality for accurately retaining the contents of strings.

More info on the problem here:

And a visual of how the data parsing should work...

When I use:


The result from .data() should simply be equivalent to this:

   var variable = jQuery.parseJSON( $("div").attr("data-variable") );
   var variable = $("div").attr("data-variable");

But instead it is not simply parsing JSON first, it is parsing everything except strings, and leaving anything else as raw, unparsed strings.

The bug submitted sounds a lot like #7231. I'll reference your ticket in the other thread but will be closing this as a duplicate as both refer to the broken string support.
