I use the following code:

'window.status=\'' + this.items[i].url.replace("\.\./", "").replace("\./", "").replace("\.html", "").replace("\.htm", "").replace("\.php", "") + '\'; return true" ' +
 (thanks, Basilisci:

Now I want to change it so that _ becomes a space and each word is capitalized, like this:


 should become

      Hello World

Any ideas?

Probably on the errorous part replace.replace(/ (there should only be a single replace)

Hm, I just wrote this function, and then I see Roonaan already answered this. Well, here it is anyway:

function rpStr(text){
var tmpStr = new String(text);
      return tmpStr.replace(/_/g, " ").replace(/(^| )./g, function(a){
            return a.toUpperCase();

It very neatly replace underscores and capitalizes words. Enjoy.

'window.status=\'' + this.items[i].url.replace("\.\./", "").replace("\./", "").replace(/\.(html|htm|php)/ig, "").replace(/_/g, ' ').toLowerCase().replace(/\b[a-z]/g, titleCase) + '\'; return true" ' +

and have this function in the page...
        function titleCase() {
            return arguments[0].toUpperCase();
