Question

所以我正在努力学习如何制作谷歌地图。我对javascript的了解很少，但我想在这里学习。

我在网上引用了一个代码，并且我已经明白了如何添加位置，标记和信息，但我正在试图找出如何为每个标记添加多个自定义图标。

感谢您的帮助。

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);

有多种方法，最简单的方法是将标记的图标属性设置为您想要显示为标记的图像的网址。

样品：

//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]
            });

    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]
    ];

地点代表一系列地区，后面是他们的posicón，特别是其纬度和经度，所以他们将被定位在谷歌的地图上，并不总是以这种方式发送纬度和经度，所以你可以接收数据库或json。我希望我能帮到你。

  <script type="text/javascript">
