Javascript really is a cute language. I just discovered, or rather, have read it in Mark Birbeck’s post that the Javascript replace function can take a function as section parameter.

Here is my go at an implementation of the strtr() function of PHP in Javascript – neat!

  function strtr(text, obj) {
    return text.replace(/§(\w+)/g, function(m) {
      if (typeof(obj[RegExp.$1]) == 'undefined') {
        return m;
      }
      else {
        return obj[RegExp.$1];
      }
    });
  }

This will replace all occurences of §bla in text with an object property obj.bla.
