title: Clear all script-set variables easily (Javascript/jQuery)
body: <p>I'm trying to find a simple way to reset all current variables in the DOM. My app has a 'locked' state, but currently, when locked, the last set of information is still visible in the DOM if you look using Firebug for example.</p>
  
  <p>I know all the names of all variables, but I don't want to have a really cumbersome script including all of them (there are approx. 300) where I explicitly clear their values.</p>
  
  <p>Does anybody know if there's a way to 'purge' the DOM of all set vars?</p>
  
  <p>Apologies in advance if this is a silly question, and thanks for any responses. My app uses jQuery extensively, but all my Javascript/jQuery searches have come up blank.</p>
