Quicktip: @Trim in JavaScript

Just needed this one - thought you might find it helpful as well, so I am blogging it:

If you need to simulate @Trim (formula) / fulltrim (Lotusscript) in JavaScript (string-only), you can do so with the following function using regular expressions:

function trim(txt) {
   return txt.replace(/(^ +| +$)/g,'').replace(/ +/g, ' ');
}
