/* Query Sting 
To get query string using Javascript:
hu = window.location.search.substring(1);
document.write(hu);

-We create a variable hu
-Built-in Javascript properties: window.location is the entire url. search.substring(1) is the part after the question mark.
-We write the value of hu to the browser.

 var f = querySt("Update");
 f = f.toLocaleLowerCase();
