title: Client-side html page with Javascript form data that persists when submit
body: <p>Is it be possible to build a pure Html page (no php, no asp, no server-side) with a form that, though javascript only, will preserve its selected checkbox upon submission?</p>
  
  <p>More specifically, I need to build a table that updates itself in realtime (as excel does with formula calculations) when some checkboxes are clicked.
  I cannot find a way to store a checkbox's state because on every page refresh (form submission action) the javascript variables will be reset.</p>
