利用谷歌地图API获取点与点的距离的js代码

复制代码 代码如下:

var request;
var distanceArray = [];
function getdistance() {
distanceArray = [];
var directionsService = new google.maps.DirectionsService();
for (var a = 0; a < pointsArray.length; a++) {
for (var b = 0; b < pointsArray.length; b++) {
if (a != b) {
request = null;
request = {
origin: pointsArray[a],
destination: pointsArray[b],
travelMode: google.maps.DirectionsTravelMode.DRIVING,
unitSystem: google.maps.DirectionsUnitSystem.METRIC
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
var myRoute = response.routes[0].legs[0].distance.value; //路线长度
distanceArray.push(myRoute);
}
});
}
}
}
}
