Element.scrollWidth

« Element

The Element.scrollWidth read–only property returns either the width in pixels of the content of an element or the width of the element itself, whichever is greater. If the element is wider than its content area (for example, if there are scroll bars for scrolling through the content), the scrollWidth is larger than the clientWidth.

This property will round the value to an integer. If you need a fractional value, use element.getBoundingClientRect().

Syntax

xScrollWidth is the width of the content of element in pixels.

     style="width: 100px; height: 200px; overflow: auto;"

       onclick="alert(document.getElementById('aDiv').scrollWidth);">
