1. 鼠标移动触发调用JavaScript:
<td onMouseOver="popmenu(this, <%=rsSub("ID")%>)" onMouseOut="menuout(this)" >test </td>
2. JavaScript的方法如下:
function popmenu(HeadMenu, intDownSubID)
{
HeadMenu.className = "over";
SubPopMenu.style.top = getposOffset(HeadMenu, "top") + HeadMenu.offsetHeight/2 + 8;
SubPopMenu.style.left = getposOffset(HeadMenu, "left") + HeadMenu.offsetWidth/2-42;
try{
var url = "index.asp?DownSubID=" +escape(intDownSubID);
xmlHttp.open("POST",url,true);
xmlHttp.send(null);
}catch(exception){}
SubPopMenu.style.display = "block";
}
3.XMLHttp的引用代码很简单如下:
if (!xmlHttp && typeof XMLHttpRequest != "undefined") {
xmlHttp = new XMLHttpRequest();
}
4.本身的页为为index.asp,为什么用
intSubID = Request("DownSubID") //这里取不到值,请大侠指教.
Response.Write(intSubID)
xmlHttp.open("GET",url,true);
xmlHttp.onreadystatechange = getData;
xmlHttp.send(null);
function getData()
{
if(xmlHttp.readyState==4 && xmlHttp.status==200) alert(xmlHttp.responseText)
}
按照楼上的方法,怎么还是在其本身的Index.asp取不到值呢?
回调函数改这样试试
