How to execute some jQuery or JavaScript code after a redirect has completed

Question

How can I execute jQuery/JS code as soon as a jQuery/JS redirect like...

$(location).attr(\'href\',\'/target_path\');

...or...

Answer 1

var x = "It's some text";
var loc = '/target_path';

loc += '?message=' + encodeURI(x);

The JS file on the new page can then look at the query string to see if a message is there, and do the required action if it's detected.

You can use window.location.search on the new page to see what's there, although I'd recommend hunting for a deparam function in a library to turn the query string into a more usable object.
