Shaun Inman’s Widon’t Ported to Javascript

I was working on some pull-quote magic today (more on that later) and needed to de-widow a string in Javascript a la Shaun Inman’s Widon’t. So I ported it to Javascript.

Here’s the magic:

String.prototype.widont = function() {
	return this.replace(/([^\s])\s+([^\s]+)\s*$/, '$1 $2');
} // end widont()

To use this simply call the widont() method on a string:

var myString	= 'Hello world!';
myString	= myString.widont();

Update (March 22, 2007): After chatting with Shaun a bit, I have updated this to match the technique that he uses in the latest version of his plugin (2.1). Thanks Shaun!
