scrollTo only if horizontal scrollbar

[anna]

How to tell if a horizontal scrollbar is present? I only want to use
scrollTo if horizontal scrollbar is present.

window.scrollba rs.visibility doesn't specify which scrollbar is
present, so it gives a false result if there is vertical scrollbar but
not horizontal scrollbar.

TIA,
Anna

You could give this a try, check for scrollWidth > clientWidth.
It works for my IE6, Netscape 7.1, Firefox 0.8.

function showscrollfeatu res() {
var msg = 'clientHeight ' + window.document .body.clientHei ght + '\n';
msg += 'clientWidth ' + window.document .body.clientWid th + '\n';
msg += 'offsetHeight ' + window.document .body.offsetHei ght + '\n';
msg += 'offsetWidth ' + window.document .body.offsetWid th + '\n';
msg += 'scrollHeight ' + window.document .body.scrollHei ght + '\n';
msg += 'scrollWidth ' + window.document .body.scrollWid th + '\n';
msg += 'scrollLeft ' + window.document .body.scrollLef t + '\n';
msg += 'scrollTop ' + window.document .body.scrollTop + '\n';
alert(msg);
}

function scrollbarcheck( ) {
var scrolling;
if ((window.docume nt.body.scrollH eight >
window.document .body.clientHei ght) ||
(window.documen t.body.scrollWi dth >
window.document .body.clientWid th))
scrolling='true ';
else
scrolling='fals e';
alert('scrollin g='+scrolling);
}

Sorry, that should have been:

function showscrollfeatu res() {
var wdb = window.document .body;
var msg;
msg += 'clientHeight ' + wdb.clientHeigh t + '\n';
msg += 'clientWidth ' + wdb.clientWidth + '\n';
msg += 'offsetHeight ' + wdb.offsetHeigh t + '\n';
msg += 'offsetWidth ' + wdb.offsetWidth + '\n';
msg += 'scrollHeight ' + wdb.scrollHeigh t + '\n';
msg += 'scrollWidth ' + wdb.scrollWidth + '\n';
msg += 'scrollLeft ' + wdb.scrollLeft + '\n';
msg += 'scrollTop ' + wdb.scrollTop + '\n';
alert(msg);
}

function scrollbarcheck( ) {
var wdb = window.document .body;
var scrolling;
if ((wdb.scrollHei ght > wdb.clientHeigh t) ||
(wdb.scrollWidt h > wdb.clientWidth ))
alert('Scrollin g=True');
else
alert('Scrollin g=False');
}
