#14587 closed bug (notabug)

DOM attributes aren't refetched during el.removeData().data()

Description

When calling .removeData() and subsequently .data() one would expect from the documentation that the result of .data() would contain the current data-* attributes from the DOM.

Instead the result of .data() is an empty dictionary!

I have a JSfiddle showing the issue:

http://jsfiddle.net/m6TV5/

The workaround for now is to call the following on each element after .removeData() and before .data():

jQuery._data(this, "parsedAttrs", false);

It seems the private parsedAttrs data isn't being cleared in removeData().

Thank you.

This seems like expected behavior. The docs state:

The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated 

Once they have been accessed, they will not accessed again. Besides, when dealing with data-* attributes, I'm inclined to recommend .attr() at this point.
