google-maps - Google Maps, open info window after click on a link

Question

i have this code to display a google map:

<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>

That's not the final code, because i want add more markers.

The problem is, that i need external links to open the info window of a marker.


For Example:

Link 1 opens the info window from marker 1
Link 2 opens the info window from marker 2
etc...

I need a link something like this:

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

Here is my code in jsfiddle: http://jsfiddle.net/fJ4jG/3/

I found couple of solutions, but i don't know how to use this code together with my code. It should work like this: http://www.geocodezip.com/v3_MW_example_map2.html

Thanks for every help!

Answer 1

该示例所做的是它创建了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，您会发送一个索引，其中包含对数组中标记的引用的函数。

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');
    }

在您的 HTMLa标记中添加如下myClick函数：

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

Answer 2

就像我的例子一样。

1. 添加一个全局数组来保存对 google.maps.Marker 对象的引用：

   var gmarkers = [];
   

2. 在创建标记时将标记推送到该数组上

   gmarkers.push(marker);
   

3. 在所需的标记上触发“点击”事件：

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

使用此代码我已经尝试过

google.maps.event.addListener(marker, 'click', function() {

                   infoWindow.setContent(locations[i][0]);
                   infoWindow.open(map, marker);


      });
