这段JS代码是什么意思呢

<script language="javascript" type="text/javascript">
function GoSearch(){
var KeyWord=document.ListForm.KeyWord.value;
var SortID=document.ListForm.SortID.value;
window.location.href="<%=ListUrl%>&KeyWord="+KeyWord+"&SortID="+SortID;
}
function Move(){
var MuliID="";
var SortID=document.ListForm.SortID2.value;
var CheckID=document.getElementsByName("CheckBoxID");
for(var i=0;i<CheckID.length;i++){
     if(CheckID[i].checked){
     MuliID = MuliID+"|"+CheckID[i].value;
   }
}      
window.location.href="<%=ListUrl%>&Action=Move&MuliID="+MuliID+"&SortID="+SortID;
}
</script>
