title: passing this object as argument in onChange event?
body: <p>I want to make an eventHandler that passes "this" object as parameter. I tried this</p>
  
  <pre><code> &lt;select id="customer" onchange="custChange(this);"&gt;
  </code></pre>
  
  <p>it works fine and get the the dom object on which on change even was called.</p>
  
  <p>But as per my understanding this should not work as first argument  is expected as "event" (not the "this" 
   object )in event handler method like below</p>
  
  <pre><code>  &lt;select id="customer" onchange="custChange(event);"&gt;
  </code></pre>
  
  <p>can we pass any argument(this or event) in eventHandler method provide their name is correct or first argument will
    always be considered as event object?</p>
