jQuery/Javascript - reload current page with an appended querystring? -

I have found a dropdown menu on my form, when something is selected I need to reload the current page , But with an attached query string.

How would I go about doing this?

This is an old question but it came in Google search results for the first time.

The solution I made is similar to that of Andy.

window.location.pathname returns the URL of the page without query string. I then "?" + $ I am able to create a query string with Param ({'foo': 'bar', 'base': 'ball'}) , after which I have a pathname and window.location.href Set on

  window.location.href = window.location.pathname + "?" + $ Ultimate ({'foo': 'bar', 'base': 'ball'})
