How can I get a specific parameter from location.search?

I have a url like the following.

http://localhost/xxx.php?tPath=&pid=37

I want to get the pid=37 but by its name because on time the url is like above and then when page refreshed then the url becomes like the following.

http://localhost/xxx.php?tPath=&action=xxx&pid=37&value=13&fname=aaaa&fone=4321122

So I want to get the pid=37. It might be a function to which I pass the pid as a parameter and it returns its value.

How will I do this?

Take a look at this or follow a solution like this:

function getParam( 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 results[1];
}

var frank_param = getParam( 'pid' );
