【问题描述】：

以下是我的 javascript 代码，用于在谷歌地图上显示一个标记点。

如何改为显示两个标记点？

window.onload = function () {

    'use strict';

    var latlng = new google.maps.LatLng(17.497859,78.391293);

    var styles = [];

    var myOptions = {
        zoom: 16,
        center: latlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        disableDefaultUI: true,
        scrollwheel: false
    };

    var contentString = '<div id="content">'+
        '<div id="siteNotice">'+
        '</div>'+
        '<h4>We Are Here</h4>'+
        '<p>test'</p>'+
        '</div>';

    var infowindow = new google.maps.InfoWindow({
        content: contentString
    });

    var map = new google.maps.Map(document.getElementById('map'), myOptions);

    var myLatlng = new google.maps.LatLng(17.497859,78.391293);

    var image = '../images/marker.png';
    var marker = new google.maps.Marker({
        position: myLatlng,
        map: map,
        title: 'Hello World!',
        icon: image
    });

    google.maps.event.addListener(marker, 'click', function() {
        infowindow.open(map,marker);
    });
}

【解决方案1】：

只需添加 google.maps.Marker 的新实例及其自己的位置、标题和信息窗口，然后使用 map 属性或 Marker 对象的 setMap(map) 方法将其分配给您的地图。

就像下一个

    var infowindow1 = new google.maps.InfoWindow({
        content: contentString
    });

    var infowindow2 = new google.maps.InfoWindow({
        content: contentString
    });

    var myLatlng1 = new google.maps.LatLng(17.497859,78.391293);
    var myLatlng2 = new google.maps.LatLng(17.497859,78.391293);

    var image = '../images/marker.png';

    var marker1 = new google.maps.Marker({
        position: myLatlng1,
        map: map,
        title: 'Hello World!',
        icon: image
    });
    var marker2 = new google.maps.Marker({
        position: myLatlng2,
        map: map,
        title: 'Hello World!',
        icon: image
    });

google.maps.event.addListener(marker1, 'click', function() {
    infowindow1.open(map,marker1);
});

google.maps.event.addListener(marker2, 'click', function() {
    infowindow2.open(map,marker2);
});

感谢您的重播。它会显示在同一张地图上吗？我的意思是这两个点会显示在一张地图上吗...？
@user3635258 当然，因为您将其分配给一个地图对象

<script type="text/javascript">
    var locations = [
      ['ModelTown Lahore', 31.484665, 74.326204, 4],

      ['Mughalpura Lahore', 31.573261, 74.363712, 2],
      ['WapdaTown Lahore', 31.425724, 74.266895, 1]
    ];

    var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 11,
        center: new google.maps.LatLng(31.435684, 74.304661),
        mapTypeId: google.maps.MapTypeId.ROADMAP
    });

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

    var marker, i;

    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,
            animation: google.maps.Animation.BOUNCE,
        });

        google.maps.event.addListener(marker, 'click', (function (marker, i) {
            return function () {
                infowindow.setContent(locations[i][0]);
                infowindow.open(map, marker);
            }
        })(marker, i));
    }

请使用以下代码绘制任意数量的标记；-)
