以下是引用片段：

<script type="text/javascript">
function check()
{
        var sWidth =window.screen.availWidth;
        var nWidth =document.body.offsetWidth;
        if (nWidth<sWidth)
         

        window.moveTo(0,0);
        window.resizeTo(screen.availWidth,screen.availHeight);
}
check();
</script>
