// Given a query string "?to=email&why=because&first=John&Last=smith" | |
// getUrlVar("to") will return "email" | |
// getUrlVar("last") will return "smith" | |

// To convert it to a jQuery plug-in, you could try something like this: | |
(function($){ | |
$.getUrlVar = function(key){ | |
var result = new RegExp(key + "=([^&]*)", "i").exec(window.location.search); | |
return result && unescape(result[1]) || ""; | |

I'm new to this so I apologize if this is obvious to some....
But how do I call getUrlVar(key) and use the result in another link
on my html page?
For example: http://FirstUrl.com/?id=123456
I need to extract the id (123456) from the First Url and use that
in my Second Url so the link is Clickable.
href=http://SecondUrl.com/?id=123456
Any help gratefully accepted, it's driving me nuts!!!
Thank you! THANK YOU! This helped me so much!
