AJAX实现鼠标经过弹出详细介绍
很老很久的一个话题和技术,可是依然找不到以前写的代码,现在拿出来,免得以后乱找,技术实现,鼠标放在超链接上触发JS实现弹出详细简介。
<script type="text/javascript">
	var eposx ;
	var eposy ;
	function showRequest(pid,event){
		eposx = event.clientX;
		eposy = event.clientY;
		var url="tip.jsp";
		var params = 'pid='+ pid + '&time=' + (new Date()).toString() ;
		sendRequest(url,params,'GET',showDetail);			
	}
	
	//动态加载数据部门列表
	function showDetail(){
		if (httpRequest.readyState == 4) { 
			if (httpRequest.status == 200) {
				var membersData = httpRequest.responseXML.getElementsByTagName("member");
				var membersList = document.getElementById("detail");
				//循环将数据插入列表框中
				var li = '<table>';
				for(var i=0;i<membersData.length;i++){
					var price=membersData[i].childNodes[0].firstChild.nodeValue;
					var num=membersData[i].childNodes[1].firstChild.nodeValue;
					var chandi=membersData[i].childNodes[2].firstChild.nodeValue;
					li += '<tr><td>价格:' + price + '</td></tr>';
					li += '<tr><td>数量:' + num + '</td></tr>';
					li += '<tr><td>产地:' + chandi + '</td></tr>';
				}
				li += '</table>';
				membersList.innerHTML = li;
				setDivPosition();
				membersList.style.visibility='visible';
			} else { //页面不正常 
				alert("您请求的页面有异常"); 
			}
		}
	}
	
	function hidendiv(){
		var membersList = document.getElementById("detail");
		membersList.innerHTML = '';
		membersList.style.visibility='hidden';
	}
	
	function setDivPosition(){
		var goodslist = document.getElementById('goodslist');
		eposx = goodslist.offsetLeft + goodslist.offsetWidth -2;
		eposy += goodslist.offsetTop - 100;
		var listdiv = document.getElementById('detail');
		listdiv.style.left=eposx+'px';
		listdiv.style.border='blue 1px solid';
		listdiv.style.top=eposy + 'px';
		listdiv.style.width='100px';
		listdiv.style.zIndex='999';
	}
</script>
