我无法弄清楚出了什么问题？
答案 0 :(得分：1)
检查此JSBin：http://jsbin.com/bacoyor/4/edit?js,output
我在以下代码中将'posision'更改为'position'：
var marker = new google.maps.Marker({
map: map,
-> position: posision,
title:title,
animation: google.maps.Animation.DROP,
id: i
});
和
bounds.extend(Markers[i].position);
我还将用于加载Google Maps JavaScript API的脚本移动到正文标记的末尾。
