You'll better advised to share a link to a code playground project where you had save your whole code (html/css/js): actually, you provide only the js script, and we cannot guess wich elements you're accessing and attempting to set the disabled attribute...

Anyway, I gyess you're misusing this attribute: it only apply/works on form controls in major browsers... more about that here:
