常用小的特效（确认删除弹窗、返回顶部）

1、确认操作（如删除）弹窗。

 <script language="javascript">
    function delcfm() {
        if (!confirm("确认要删除？")) {
            window.event.returnValue = false;
        }
    }
</script>

<input name="" type="submit" value="删除" onClick="delcfm()" /></form>

 18 Changes by Nick Fetchak:
 19 - IE8 standards mode compatibility
 20 - VML elements now positioned behind original box rather than inside of it - should be less prone to breakage
 21 - Added partial support for 'box-shadow' style
 22 - Checks for VML support before doing anything
 23 - Updates VML element size and position via timer and also via window resize event
 24 - lots of other small things
