Google地图路线规划

Google地图路线规划：

需求：给定的两点之间Google地图路径规划和详情。

代码实现：

//map定义省略

var directionsDisplay = new google.maps.DirectionsRenderer({ 'draggable': true ,suppressInfoWindows:true,suppressMarkers:true});

var service;

//得到规划路线
function getRoute(source,destination,map){
    var directionsService = new google.maps.DirectionsService();
    directionsDisplay.setMap(map);
    var request = {
        origin: source,
        destination: destination,
        travelMode: google.maps.TravelMode.DRIVING
    };
    directionsService.route(request, function (response, status) {
        if (status == google.maps.DirectionsStatus.OK) {
            directionsDisplay.setDirections(response);
        }
    });
}

//得到规划路径的详细些信息
function getDetailsRoutes(source,destination,map){
    service = new google.maps.DistanceMatrixService();
    service.getDistanceMatrix({
        origins: [source],
        destinations: [destination],
        travelMode: google.maps.TravelMode.DRIVING,
        unitSystem: google.maps.UnitSystem.METRIC,
        avoidHighways: false,
        avoidTolls: false
    }, function (response, status) {
        if (status == google.maps.DistanceMatrixStatus.OK && response.rows[0].elements[0].status != "ZERO_RESULTS") {
            var distance = response.rows[0].elements[0].distance.text;
            var duration = response.rows[0].elements[0].duration.text;
            var dvDistance = document.getElementById("siteinfo_modal_label");
            dvDistance.innerHTML = "";
            dvDistance.innerHTML += "Distance: " + distance + "<br />";
            dvDistance.innerHTML += "Duration:" + duration;

        } else {
            alert("Unable to find the distance via road.");
        }
    });
