Where is the jQuery data method information located?

Question

Can i do

<div class="some_div">some div</div>
<script>
    jQuery('.some_div').data('some_data','some info').remove();
</script>

where is the information added by the data method still around the DOM? Do I need to uninitialize? Is the information automatically deleted when the div element has no links?

Answer 1

Data is stored in a variable accessible to jQuery objects through closure. It is never saved in dom. The delete method deletes data along with the DOM element.
