- var oP = oDiv.getElementsByTagName("p")[0];
- var i =0;
- for(i=0;i<aLi.length;i++){
- aLi[i].index = i;
- aLi[i].onmouseover = function(){
- oP.style.display = "block";
- oP.innerHTML=aData[this.index];
- for(i=0; i<=this.index;i++){
- aLi[i].className="active";
- }
- };
- aLi[i].onmouseout = function(){
- oP.style.display = "";
- for(i=0; i<aLi.length; i++){
- aLi[i].className="";

- alert(this.index +1);
- };
