javascript - How to trigger the toggle on one click instead of two -

i using simple toggle this:

   function toggle_visibility(id) {    var e = document.getelementbyid(id);    if(e.style.display == 'block')       e.style.display = 'none';    else       e.style.display = 'block'; } 

and html this:

 <div id="income">  <h5 onclick="toggle_visibility('incometoggle');">income</h5>  <div id="incometoggle">     <h6>income total</h6>   </div>    </div>   

at moment, need click twice on heading div close. how can make close 1 click?
