How about:

/\?id\=|&id\=/i.test(location.href)

I would tweak @KooiInc's answer to location.href.match(/(\?|&)id($|&|=)/). It catches parameters without values (for example http://localhost:1112/Project/TestCourse.aspx?id) and also ensures you only have id not just a param starting with id (e.g idparam).

use location.href.match(/\?id\=/i) && location.href.match(/&id\=/i)
