Question

So I’ve got this bookmarklet which allows me to quickly switch to the test server version of whatever page I’m on:

javascript:(function() {window.location=window.location.toString().replace(/^http:\/\/www\./,'http://www-test.');})()

I’d also like to be able to switch to debug mode on my webpages, so I tried making a bookmarklet as below, but it doesn’t seem to work:

javascript:(function() {window.location=window.location.toString().replace(/^php/,'php?action=debug');})()

What did I screw up?

Answer 1

/^php/ only affects a string which starts with php. Since the location.href property always includes the protocol, your code doesn’t do anything.

You might be looking for /php$/, which matches php at the end of the string.

To avoid an accidental refresh upon activation of the bookmarklet, you can use:

javascript:(function(){
     if(/php$/.test(location.href)) location.href += '?action=debug';
})()
