Trigger jQuery click event with url parameter?

Question

I have a jQuery click function on my page which triggers the opening of a feedback form div. Basically I want to specify a url that will trigger this event without it needing to be clicked. Such as foo.com?formopen

Is this possible? I'm thinking I need to pass some data through the url but not sure how to go about it.

Answer 1

Use a hash in your URL like:

foo.com#formopen

Then find that hash on load like:

$(function(){

   if (window.location.hash){
      var hash = window.location.hash.substring(1);
      if (hash == "formopen"){
         openFeedbackForm();
      }
   }

});
