Solution

  • You have syntax error , )} missing .

    addEventListener('click', function({

    Looks like callback but you need just function(){} to attach.

     window.addEventListener('load',function(){      


   document.getElementById('submit').addEventListener('click', function(){
   
     document.getElementById('myDiv').innerHTML= 'hello';
     
   }, false);


 }, false);
    <input type="submit" value="submit" id="submit">
<br/>
<br/>
<div id="myDiv" style="background-color:black;color:lime;width:300px" > ... </div>
