谷歌地图多个自定义标记

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.

谢谢您的帮助.

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icon-property设置为要显示为标记的图像的URL.

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]
            });
