title: Disable submit button for a short period of time with jQuery?
body: <p>[I am quite new to jQuery so don't blame me if I get something wrong]</p>
  
  <p>I have been browsing questions here on SO about: "Disable submit button after click". OK there are loads of these stuff around, but I couldn't find out how to disable it for a limited time. e.g. 20 secs.</p>
  
  <p>Maybe I am the idiot but how?</p>
