推荐答案

google.maps.LatLng需要的两个的参数。您正在使用： GPS 的。既然你不说有什么价值的 GPS 的样子，这应该让你开始。

google.maps.LatLng requires two arguments. You are using one: GPS. Since you don't say what the value of GPS looks like, this should get you started.

替换：

var GPS='<%=GPS %>'

与

var GPS = '<%=GPS %>'.replace(/ /g, '').split(',');

替换：

var LatLng = new google.maps.LatLng(GPS);

与

var LatLng = new google.maps.LatLng(GPS[0], GPS[1]);
