How do I pass an id to a function??
Or is this even possible.

HTML Code:
<html>
<head>
<title>
  JavaScript array passing example
</title>
<script type="text/javascript">

function init(){
   display(addText1);
   display(addText2);
   display(addText3);
   display(addText4);
}

function display(var myText){
  var newText = '<h2>' + "Will this change anything..." + '</h2>';

   document.getElementById('myText').innerHTML = newText;
}
</script>
</head>
<body onload="init()">

<div id="addText1"></div>
<div id="addText2"></div>
<div id="addText3"></div>
<div id="addText4"></div>
</body>
</html>
