HELP: extracting JSESSIONID from document.cookie

What is the industry standard/professional way to extract JSESSIONID=SESSION from document.cookie?
so that finally SESSION is var "session_id"?

Pretty much so that most possible browsers are supported and fail safe...

Thank you very much...

Thank you archrajan;

I have found it at: http://www.quirksmode.org/js/cookies.html
function readCookie(name)
{
      var nameEQ = name + "=";
      var ca = document.cookie.split(';');
      for(var i=0;i < ca.length;i++)
      {
            var c = ca[i];
            while (c.charAt(0)==' ') c = c.substring(1,c.length);
            if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
      }
      return null;
}

So I guess I call it as: readCookie("JSESSIONID") ?

PS forgot to post in original file:
(Actual code that examples a practical working solution is obviously the best solution...)
I have cooked up a 'home' solution, but and will post it regardlessly later to admire or laugh at, but am looking for professional answer/solution...

There is no other professional answer/solution
