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

If it's not set or want to update with a new value you can use:

window.location.search = 'param=value'; // or param=new_value

This is in simple Javascript, by the way.

EDIT

You may want to try using the jquery query-object plugin

window.location.search = jQuery.query.set("param", 5);
