Example

This example uses the scrollWidth property to compare the rendered width of a DIV element with the width of the content. The width of the element, as rendered on the page, is exposed through the offsetWidth property.

When the overflow property is set to auto, the content can exceed the dimensions of an element, and scroll bars appear. You can use the scrollWidth property to retrieve the width of the content within the element.

Sample Code
<SCRIPT>
function fnCheckScroll(){
   var iScrollWidth = oDiv.scrollWidth;
   var iOffsetWidth = oDiv.offsetWidth;
   var iDifference = iScrollWidth - iOffsetWidth;
   alert("Width: " + iOffsetWidth
      + "\nContent Width: " + iScrollWidth
      + "\nDifference: " + iDifference); 
}
</SCRIPT>
:
<DIV ID=oDiv STYLE="overflow:scroll; height=200; width=250; 
   text-align:left">
:
</DIV>
<INPUT TYPE=button VALUE="Check scrollWidth" 
   onclick="fnCheckScroll()">
