How to pass a parameter to a javascript through a url and display it on a page?

Question

For instance, I have a url like this : www.mysite.com/my_app.html

How do I pass a value \" Use_Id = abc \" to it and use javascript to display on that page ?

Answer 1

www.mysite.com/my_app.html?use_id=abs

var qs = new QueryString()

// use_id is now available in the use_id variable
var use_id = qs.get("use_id");
