Try to save the document with Ctrl + S keyword, and then execute the code.

Solution 2:[2]

This code seems to work:

<h2>Browser Object Model (BOM) properties</h2>   

<script type="text/javascript">    
    // fixed some space's
    function prpt() {   
      document.write("The innerHeight is :"+window.innerHeight+"<br>"); //inner height   
      document.write("The innerWidth is :"+window.innerWidth); // inner width    
    }   

</script>      

<input type="button" value="innerHeight_Width" onclick="prpt()">
