How can I add or update a query string parameter?

Question

With javascript how can I add a query string parameter to the url if not present or if it present, update the current value? I am using jquery for my client side development

Answer 1

By using jQuery we can do like below

var query_object = $.query_string;
query_object["KEY"] = "VALUE";
var new_url = window.location.pathname + '?'+$.param(query_object)

In variable new_url we will have new query parameters.
