求问。在MasterPage.master 中这部分代码的具体用途是什么？谢谢~~~~~
母版页中布局完成，但是多出来这么一段的script 的代码。不知道具体的实现是什么？？？

<script language="JavaScript1.2">
function move(x) {
if (document.all) {    
object1.style.pixelLeft += x;
object1.style.visibility = "visible"}
else if (document.layers) {
document.object1.left += x;
document.object1.visibility = "show"}};
function makeStatic() {
if (document.all) {object1.style.pixelTop=document.body.scrollTop+20}
else {eval(document.object1.top=eval(window.pageYOffset+20));}
setTimeout("makeStatic()",0);}
</script>
<script language="JavaScript1.2">
function positionmenu(){
move(-100)
}
if (document.all) {document.write('<DIV ID="object1" style="visibility:hidden;cursor:hand; Position : Absolute ;Left : 100px ;Top : 120px ;100 : 120">')}
</script>
