Javascript decoding html entities [duplicate]

by 
var text="<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>";
var decoded = $('<textarea/>').html(text).text();
alert(decoded);

This sets the innerHTML of a new element (not appended to the page), causing jQuery to decode it into HTML, which is then pulled back out with .text().
