Javascript 谷歌地图多个自定义标记

所以我正在努力学习如何制作谷歌地图。我对javascript知之甚少，但我在这里尝试学习

我在网上引用了一段代码，我已经了解了如何添加位置、标记和信息窗口，但我正试图找出如何为每个标记添加多个自定义图标

谢谢你的帮助

function initialize() {

        //add map, the type of map
        var map = new google.maps.Map(document.getElementById('map'), {
            zoom: 6,
            center: new google.maps.LatLng(37.7749295, -122.4194155),
            mapTypeId: google.maps.MapTypeId.ROADMAP
        });

        //add locations
        var locations = [
            ['San Francisco: Power Outage', 37.7749295, -122.4194155],
            ['Sausalito', 37.8590937, -122.4852507],
            ['Sacramento', 38.5815719, -121.4943996],
            ['Soledad', 36.424687, -121.3263187],
            ['Shingletown', 40.4923784, -121.8891586]
        ];

        //declare marker call it 'i'
        var marker, i;

        //declare infowindow
        var infowindow = new google.maps.InfoWindow();

        //add marker to each locations
        for (i = 0; i < locations.length; i++) {
            marker = new google.maps.Marker({
                position: new google.maps.LatLng(locations[i][1], locations[i][2]),
                map: map,
            });

            //click function to marker, pops up infowindow
            google.maps.event.addListener(marker, 'click', (function(marker, i) {
                return function() {
                    infowindow.setContent(locations[i][0]);
                    infowindow.open(map, marker);
                }
            })(marker, i));
        }
    }
    google.maps.event.addDomListener(window, 'load', initialize);

函数初始化（）{
//添加地图，地图的类型
var map=new google.maps.map（document.getElementById（'map'）{
缩放：6，
中心：新google.maps.LatLng（37.7749295，-122.4194155），
mapTypeId:google.maps.mapTypeId.ROADMAP
});
//添加位置
变量位置=[
[“旧金山：停电”，37.7749295，-122.4194155]，
[Sausalito'，37.8590937，-122.4852507]，
['Sacramento'，38.5815719，-121.4943996]，
[Soledad'，36.424687，-121.3263187]，
[Shingletown'，40.4923784，-121.8891586]
];
//我叫它‘我’
var标记，i；
//声明信息窗口
var infowindow=new google.maps.infowindow（）；
//将标记添加到每个位置
对于（i=0；i

有多种方法，最简单的方法是将标记的图标属性设置为要显示为标记的图像的URL

样本：

//modified array with icon-URLs
var locations = [
            ['San Francisco: Power Outage', 37.7749295, -122.4194155,'http://labs.google.com/ridefinder/images/mm_20_purple.png'],
            ['Sausalito', 37.8590937, -122.4852507,'http://labs.google.com/ridefinder/images/mm_20_red.png'],
            ['Sacramento', 38.5815719, -121.4943996,'http://labs.google.com/ridefinder/images/mm_20_green.png'],
            ['Soledad', 36.424687, -121.3263187,'http://labs.google.com/ridefinder/images/mm_20_blue.png'],
            ['Shingletown', 40.4923784, -121.8891586,'http://labs.google.com/ridefinder/images/mm_20_yellow.png']
        ];



//inside the loop
marker = new google.maps.Marker({
                position: new google.maps.LatLng(locations[i][1], locations[i][2]),
                map: map,
                icon: locations[i][3]
            });

Locations表示一组地区，后面紧跟着他们的posicón，特别是其纬度和经度，因此它们将被定位在谷歌地图上，而不总是以这种方式发送纬度和经度，因此您可以接收数据库或json。希望我能帮上忙。
