title: How to make a real "onchange" event in HTML (no jQuery)?
body: <p>Please note: I do not want to use <code>jQuery</code> for this (otherwise I like it)</p>
  <p><strong>Problem:</strong> I have come to situation where I need to do some javascript function after an user changes an input field (e.g. <code>input type=&quot;text&quot;</code>). So I said to myself - I remember an <code>onchange</code> event - <strong>BUT</strong> <code>onchange</code> event runs AFTER user leaves the field, but I need the function to be called for example every time user types a character to that field. Wowhead shows nice example of what I am trying to achieve <a href="http://www.wowhead.com/search?q=portal%20trainer" rel="nofollow noreferrer">this</a> (field with placeholder &quot;Search within results...&quot;)</p>
  <p><strong>Summary:</strong> I am looking for a SIMPLE way of detecting REAL <code>onchange</code> event(<a href="http://www.w3schools.com/jsref/event_onchange.asp" rel="nofollow noreferrer">not the classic HTML one</a>)and through that call a JS function while not using jQuery?</p>
