$.fn.removeData can't delete data

[caii]

$('body').data('a',1);

$('body').removeData();

alert($('body').data('a')) still 1

alert($.expando in document.body) still true

Is it bug or my mistake? and jQuery.support.deleteExpando does not exist in 1.4.3

Bug confirmed. removeData() fails in 1.4.3 (removeData(name) still works).

It looks like the jQuery.support.deleteExpando property (and the according test in support.js) got removed by accident.

Commit where the deleteExpando property was introduced ​#9195107 (improvement on the previous commit ​#a6f3375)

Commit where the functionality was removed ​#141ad3c

#7210 is a duplicate of this ticket.

[John Resig]

We removed deleteExpando after 1.4.2, for some reason. This caused problems with removeData() (no arguments). Fixes #7209.
