Question

I have the code

  <script type="text/javascript">
  var yourImg = document.getElementById('image');
  if(yourImg && yourImg.style) {
    yourImg.style.height = screen.availWidth;
   yourImg.style.width = screen.availHeight;
  }
  </script>

And I need to append px to the end of the width and height.

Thanks in Advance,
Chase

Concatenation of strings (and other values) in javascript is made using the “+” (plus) character. In your code:

 <script type="text/javascript">
  var yourImg = document.getElementById('image');
  if(yourImg && yourImg.style) {
    yourImg.style.height = screen.availWidth;
    yourImg.style.width = screen.availHeight;
    var height = yourImg.style.height + 'px';
    var width = yourImg.style.width + 'px';
   }
  </script>
