或者使用前面的代码：
…
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，就可以直接识别坐标，而不是从字符串计算。

还有另一种解决方案:将像这样的对象传递到源和目标
