function MouseOverHand(ID)

<body>
<label id="Hand" onmouseover="MouseOverHand('Hand');" > Hand </label><br/><br/>
<label id="Help" onmouseover="MouseOverHelp('Help');" > Help </label>
</body>

</html>

In the above html is used to take mouse cursor in the mouse over of label's. Here "Hand" and "help" cursor is working fine in internet explore but its not working in firefox and other browser's

hoping your support,

回答1:

you don't need var Cursor if you can specify help or hand directly like so

document.getElementById(ID).style.cursor='hand';

and

document.getElementById(ID).style.cursor='help';

please check working example and take a look at the html source code

回答2:

Simpler version, works on 'all' browsers:

<script type="text/javascript" >
function MouseOverPointer(obj) //obj is the triggering element
{
    if(obj.id=='Help')
        obj.style.cursor = "help";
    else if(obj.id=='Hand')
        obj.style.cursor = "pointer";
}
</script>

<label id="Hand" onmouseover="MouseOverPointer(this);" > Hand </label><br/><br/>
<label id="Help" onmouseover="MouseOverPointer(this);" > Help </label>
