var point = new BMap.Point(data.pointX, data.pointY);
function result(point){
var poi2;
var keyword2 ='科技园';
//document.getElementById('end').value;
var local2 = new BMap.LocalSearch(map, {
renderOptions: {map: map}
});
local2.search(keyword2);
local2.getResults();
local2.setSearchCompleteCallback(function(searchResult)
{
poi2 = searchResult.getPoi(0);
var Transit = new BMap.TransitRoute(map, {renderOptions: {map: map, panel: "abc", autoViewport: true}});
Transit.search(point,poi2);
poi2=point=null;
});
}
point 是从别函数中传过来的坐标
不管怎么传起点对象，为什么在地图中它的起点总是固定的地点，终点我设置的是一个。

poi2=point=null;都置空了？啥意思？Ajax是异步加载的哦。
poi2 = searchResult.getPoi(0); 这样得不到点，要Results.getPoi(0).point才行。
