$.data throws "string.replace is not a function" on invalid input

[rodneyrehm]

$.data($(document.body), {test: 2}, 'yadda');

leads to »string.replace is not a function« on line 622. The given arguments (seeing name={} value='yadda') don't make much sense. $.data() should react accordingly. Either ignore 'yadda' or throw an error of its own. Identifying errors like the above is cumbersome.

A simple return; after Lines 1755 and 1773 could suffice.

Identifying errors like the above is cumbersome.

True, but catching even a small subset of incorrect invalid arguments being passed to jQuery's methods would expand the code significantly. We aren't going to head down that road.

I feel the need to point out that there is a MUCH bigger error here...

$.data( $(document.body) ) will store data on the jQuery collection object, not the DOM element underneath it. I think you might of meant $.data( document.body, .... )
