    Passing to a Function

    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>

    The value of an HTML attribute is a Primitive: a string. Pass it as a string, then. And take care about how you use the quotes.
    Code:
    function init(){
       display("addText1");
       display("addText2");
       display("addText3");
       display("addText4");
    }
    function display(id){
      var newText = "<h2>Will this change anything...</h2>";
    
       document.getElementById(id).innerHTML = newText;
    }
