Javascript documentation on getParameterByName?

Question

I can't seem to find any detailed documentation on getParameterByName(). I've searched Mozilla, Google, and here. Am I missing something?

We use this where I work. Similar to ThiefMaster's solution...

function getParameterByName( name ){
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results == null )
    return "";
  else
    return decodeURIComponent(results[1].replace(/\+/g, " "));
}
