谷歌地图,点击链接后打开信息窗口

Question

我有这个代码来显示谷歌地图:

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script type="text/javascript">
function initialize() {

        var mapOptions = {
            zoom: 10,
            center: new google.maps.LatLng(40.714364, -74.005972),
            mapTypeId: google.maps.MapTypeId.ROADMAP
        }
        var map = new google.maps.Map(document.getElementById("googlemap"), mapOptions);


        var locations = [
            ['New York', 40.714364, -74.005972, 'http://www.google.com/intl/en_us/mapfiles/ms/micons/green-dot.png']
        ];


        var marker, i;
        var infowindow = new google.maps.InfoWindow();


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


        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,
                icon: locations[i][3]
            });


            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);
</script>
<div id="googlemap" style="width: 100%; height: 500px;"></div>
<a href="#">Open Info Window</a>

这不是最终的代码,因为我想添加更多的标记.

问题是,我需要外部链接来打开标记的信息窗口.


例如:

链接1从标记1
打开信息窗口链接2打开标记2
等信息窗口...

我需要这样的链接:

<a href="javascript:marker(0)">Open Info Window One</a>

这是我在jsfiddle中的代码:http: //jsfiddle.net/fJ4jG/3/

我找到了几个解决方案,但我不知道如何将此代码与我的代码一起使用.它应该像这样工作:http: //www.geocodezip.com/v3_MW_example_map2.html

谢谢你的帮助!

Answer 1

这个例子的作用是创建一个存储标记的数组.因此,当创建标记时,它们会被推送到该标记数组.当您单击链接时,您将发送一个索引,该索引的函数是对数组中标记的引用.

所以JavaScript看起来像这样:

var markers = [];
// The array where to store the markers

function initialize() {

        var mapOptions = {
            zoom: 10,
            center: new google.maps.LatLng(40.714364, -74.005972),
            mapTypeId: google.maps.MapTypeId.ROADMAP
        }
        var map = new google.maps.Map(document.getElementById("googlemap"), mapOptions);


        var locations = [
            ['New York', 40.714364, -74.005972, 'http://www.google.com/intl/en_us/mapfiles/ms/micons/green-dot.png']
        ];


        var marker, i;
        var infowindow = new google.maps.InfoWindow();


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


        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,
                icon: locations[i][3]
            });

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

            // Push the marker to the 'markers' array
            markers.push(marker);
        }

    }
    google.maps.event.addDomListener(window, 'load', initialize);

    // The function to trigger the marker click, 'id' is the reference index to the 'markers' array.
    function myClick(id){
        google.maps.event.trigger(markers[id], 'click');
    }

在HTML a标记中添加如下myClick函数:

<a href="#" onclick="myClick(0);">Open Info Window</a>

Answer 2

在我的例子中.

1. 添加全局数组以保存对google.maps.Marker对象的引用:

   var gmarkers = [];
   

2. 在创建它们时将标记推到该数组上

   gmarkers.push(marker);
   

3. 触发所需标记上的"单击"事件:

   <a href="javascript:google.maps.event.trigger(gmarkers[0],'click');">Open Info Window</a>
