For more information about how to access the dimension and location of objects on the page through the Dynamic HTML (DHTML) Object Model, see Measuring Element Dimension and Location.

Example

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.
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.
<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()">
