还是使用以前的代码：

… 
var start = new google.maps.LatLng('37.7683909618184', '-122.51089453697205'); 
var end = new google.maps.LatLng('41.850033', '-87.6500523'); 
var request = { 
    origin:start, 
    destination:end, 
    travelMode: google.maps.DirectionsTravelMode.DRIVING 
}; 
directionsService.route(request, function(response, status) { 
    … 
} 
…

这样的坐标直接承认的，而不是从字符串进行评估。

又一解决方案：传递一个对象等，以出发地和目的地

{lat: 39.904309, lng: 116.385871}
