size of TextNode - DOM Hack

hackTheDom.js

// This is the coolest code snippet I (Mr. Mad) have every created
// It will magicly get the size of a textnode, by createing a context
// range and get the client rects of that range.
// It will then combine the rects to one rect, and thereby get the size
// of the text node.
// Note that by any standarts a TextNode has no size.
var range = document.createRange();
    range.selectNode(node);

var rect = range.getBoundingClientRect();
// The magic ends here

dude, that's awesome.
