Determine if scrolling is required ....

[furan]

All,
I am maintaining a bundle of pages which have all had an icon tagged to the bottom which redirects the user to the top of the page i.e. xxx.htm#Top. This is all well and good when the scrolling is required but it looks a bit dumb on pages with only one or two paragraphs on them. Is there a way in which I can determine if the scrollbars are active and if they are available to use (i.e scrolling is required) or should I continue to use the script i have which makes a rough guess at this dependant on the amount of page content...(not very accurate!)

Any help appreciated

document.body.scrollTop should tell you if there is any scrollba extended, so youcould call a funtion onLoad to check the state of scrolling.


function checkBars(){
if(document.body.scrollTop >100){
//show the 'to top' button
}
else{}
}
