Find/Replace URL's with Javascript

I recently had a need to ensure all URL's on site A were pointing to site B. What I needed was some javascript that would rewrite the URL's once the page had finished loading, and change any site A links to site B links.

Here's a handy piece of javascript that @n00b2pr0 shared with me that get's the job done.

var linkRewriter = function(a, b) {
  $('a[href*="' + a + '"]').each(function() {
    $(this).attr('href', $(this).attr('href').replace(a, b));
  });
};

linkRewriter('current-domain.com', 'desired-domain.com');
