javascript|js| Dynamic I now have a layer, there is a div in the layer, when the content is more often appear in the scroll bar, I now think, when the scroll bar appears, the width of the table div is equal to the width of the div minus the width of the scroll bar, how to dynamically get the width of the scroll bar, Or to determine whether the state of the scroll bar appears.

Is that what you want?
<div id= "Demo" style= "Width:200px;height:100px;background-color:buttonface;overflow:auto;" >
Never-online<br/>never-online<br/>never-online<br/>never-online<br/>never-online<br />never-online<br/>never-online<br/>never-online<br/>
</div>
<div id= "D2" style= "Position:absolute;background-color: #eee;" ></div>
<script>
alert (demo.offsetwidth);
alert (demo.scrollwidth);
With (D2.style) {
Top=demo.offsettop;
Left=demo.offsetleft;
Width=demo.scrollwidth;
Height=demo.offsetheight;
}
</script>
--------------------------------------------------------------------------------------If I don't get it right, can I just cut it?
<div id= "Demo" style= "Width:200px;height:100px;background-color:buttonface;overflow:auto;" >
Never-online
</div>
<div id= "D2" style= "Position:absolute;background-color: #eee;" ></div>
<script>
Alert ("div width:" +demo.offsetwidth);
Alert ("div scrolling width:" +demo.scrollwidth);
Alert ("ScrollBar width:" + (parseint (demo.offsetwidth)-parseint (demo.scrollwidth));
demo.innerhtml = "never-online<br/>never-online<br/>never-online<br/>never-online<br/> Never-online<br/>never-online<br/>never-online<br/>never-online<br/> "
Alert ("div width:" +demo.offsetwidth);
Alert ("div scrolling width:" +demo.scrollwidth);
Alert ("ScrollBar width:" + (parseint (demo.offsetwidth)-parseint (demo.scrollwidth));
With (D2.style) {
Top=demo.offsettop;
Left=demo.offsetleft;
Width=demo.scrollwidth;
Height=demo.offsetheight;
}
</script>
