新手求教.....
实习生，想问一下关于那个鼠标事件，当鼠标经过一区域的时候显示一个div框，然后鼠标移走时div框消失........怎么写？...还有这段代码什么意思，这个是关于百度地图开发的代码jQuery(document).ready(function(){
var buildinfo;
var jg;
var x = [];
var y = [];
var length;
var pointarray;
jQuery.getJSON("json/buildinginfo4x.json", function(data){
//======设置全局变量JsonData_Building=======
//数据需要在Cmap_Base中的mouseove事件中使用，判断在哪个层作画，是/否隐藏该层
//JsonData_Building = data;
//=================================
var iitmp = 0;
var oldpertmp;
document.getElementById("d_map").onclick = function(){
//alert(CZoomControl_zoomPercent[CZoomControl_zoomIndex]+""+Base_OldPercentTmp);
if (isInsidePolygon(_Theodolite$point.x, _Theodolite$point.y, pointtmp, 0.8, CZoomControl_zoomPercent[CZoomControl_zoomIndex])) {
//JqueryMarker$strMsg(data.building[iitmp].title);//弹出消息
var div_3d = document.createElement("Div");
div_3d.id = "div_showbuildinfo";
//str = "<iframe src='flash/Test11_mv.html' width='800' height='500' frameborder='no' border='0' marginwidth='0' marginheight='0' scrolling='no'></iframe>";

}麻烦高手给讲解一下~谢谢 地图 --------------------编程问答--------------------
没人么~~~~~~~哪位高手指教一下~谢谢。
--------------------编程问答--------------------
咱只能回答上来第一个问题你在div上面绑定事件，当鼠标移动到上面就触发事件，将div显示出来，移出就将div隐藏掉，具体的事件自己去查一下
http://www.cnblogs.com/wei2yi/archive/2011/11/29/2267072.html --------------------编程问答-------------------- jQuery(document).ready(function(){} 这个东西呢，是表示你Jsp页面加载完成之后，就执行的函数。
document.getElementById("d_map").onclick = function(){} 这个东西呢，是当你点击id为d_map的时候，执行的函数。
document.getElementById("d_map").onmousemove = function(){} 这个呢，就是你鼠标离开那个id味d_map时所做的操作。
补充：Java , Web 开发
