动画上的多个测地折线符号(Animate symbol on multiple geodesic p

我想动画符号虽然多个测地折线...我累了要做到这一点在for循环中。 行拿得出，但圆圈（符号）不只是animate..it在起点留在了这里是我的代码。

    var poly;
    var geodesic;
    var map;
    var clickcount = 0;

    function initialize() {


        var styles = [{ featureType: "landscape", stylers: [{ color: "#000514"}] }, { featureType: "administrative.country", stylers: [{ weight: 0.1 }, { color: "#009acd"}] }, { featureType: "water", stylers: [{ color: "#1f4fa5dc"}] }, { featureType: "road", stylers: [{ color: "#000514"}] }, { featureType: "administrative.locality", stylers: [{ color: "#7cfc00" }, { visibility: "off"}] }, { featureType: "landscape.man_made", stylers: [{ visibility: "off"}] }, { featureType: "poi", stylers: [{ visibility: "off"}] }, { featureType: "administrative.province", stylers: [{ visibility: "on"}]}];
        var mapOptions = {
            center: new google.maps.LatLng(7.3, 80.6333),
            zoom: 3,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById("map_canvas"),
        mapOptions);
        map.setOptions({ styles: styles });

        var lineSymbol = {
            path: google.maps.SymbolPath.CIRCLE,
            scale: 2,
            strokeColor: '#FF0000'
        };


        var i;
        for (i = 0; i < 50; i = i + 5) {


            var flightPlanCoordinates = [
            new google.maps.LatLng(7.3, 80.6333),
            new google.maps.LatLng(23.772323 + i, -102.214897 - i)];
            var polyline = new google.maps.Polyline({
                path: flightPlanCoordinates,
                icons: [{ icon: lineSymbol, offset: '100%'}],
                strokeColor: "#FF0000",
                strokeOpacity: 1.0,
                strokeWeight: 1,
                geodesic: true                  
            });

            polyline.setMap(map);
            animateCircle();
        }
    }

    function animateCircle() {
        var count = 0;
        offsetId = window.setInterval(function () {
            count = (count + 1) % 200;

            var icons = polyline.get('icons');
            icons[0].offset = (count / 2) + '%';
            polyline.set('icons', icons);
        }, 20);
    }

请帮我在这one..i希望能看到这部作品:)非常感谢你。

Answer 1:

折线变量超出animateCircle功能的范围。 你必须使用封闭，越来越码出animateCircle功能和它的调用应该做的伎俩的粘贴。

编辑：我搞砸了封闭照常;-)你可以做这样的（再次，未经测试）：

//vars
var poliylines = new Array();

function initialize() {
    //unchanged code

    var i;
    for (i = 0; i < 50; i = i + 5) {
        //unchanged code
        polylines[i] = polyline;
        animateCircle(i);
    }
}

function animateCircle(var id) {
    var count = 0;
    offsetId = window.setInterval(function () {
        count = (count + 1) % 200;

        var icons = polylines[id].get('icons');
        icons[0].offset = (count / 2) + '%';
        polylines[id].set('icons', icons);
    }, 20);
}

发现一个简单的回答这个问题。 我使用谷歌地图API V3。 https://developers.google.com/maps/documentation/javascript/examples/overlay-symbol-animate

向下滚动下方，并点击HTML + JavaScript的标签 ，我们有可变lineCoordinates。 在这里，我们可以通过一组对象，而不是两个对象是这样的：

var lineCoordinates = [
new google.maps.LatLng(latitude1, longitude1),
new google.maps.LatLng(latitude2, longitude2),
new google.maps.LatLng(latitude3, longitude3),
new google.maps.LatLng(latitude4, longitude4)
];

动画现在将lineCoordinates所有对象发生。 在该实施例情况下，4个折线。
