title: Keep button in active state until clicked upon again
body: <p>I feel like I have a relatively simple question that I'm just not sure how to go about doing. I have an html input tag of button type which calls a javascript onclick function. This part works fine, however I want to be able to add to my onClick function, the ability to keep the button in the active state (so that it remains highlighted until clicked upon again). </p>
  
  <p>Any ideas? I tried keeping the focus on it instead, but I don't think its possible to have multiple button focuses, and that really just sounds like a hack. </p>
