Question

I am wanting to check the current url of a page and running code it is a certain url. For the script the url may be something.php?something=something. I am using JavaScript if it matters.

Answer 1

if(location.href.match(/\w+\.php\?\w+=\w+/)){
     // Do stuff   
}

Or if you meant that exact url (in which case I’m not sure why you said wildcard:

if(location.href.indexOf('something.php?something=something') !== false){
     // Do stuff   
}
