jquery - 触发 map 外的 Google map 标记

Question

当我点击 map 之外的元素时，如何触发“infoWindow”？

我有这个:

var locations = [
  ['Location 1', 59.917224,10.587052, 1],
  ['Location 2', 59.912665,10.726153, 2]
];

var map = new google.maps.Map(document.getElementById('map'), {
  zoom: 9,
  center: new google.maps.LatLng(59.913869,10.752245),
  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
  });

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

并且有一个 HTML:

<ul>
<li>Trigger Marker 1</li>
<li>Trigger Marker 1</li>
</ul>

有什么好主意吗？谢谢!

更新

在这里更新了代码:

变量位置 = [ ['位置 1', 59.917224,10.587052, 1], ['位置 2', 59.912665,10.726153, 2]];

map = new google.maps.Map(document.getElementById('map'), {
  zoom: 9,
  center: new google.maps.LatLng(59.913869,10.752245),
  mapTypeId: google.maps.MapTypeId.ROADMAP
});

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

var marker, i;

var markerMap = {}

for (i = 0; i < locations.length; i++) {
  markerMap[ "marker-" + i ] = marker  
  marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    map: map
  });

 $(".marker-list").on('click', function() {
 var id = $(this).find('li').attr( 'data-id' );
 alert(id)
 infoWindow.open( map, markerMap[ id ] );
 }); 

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

HTML:

<ul class="marker-list">
<li data-id="marker-1">Trigger Marker 1</li>
<li data-id="marker-2">Trigger Marker 1</li>
</ul>

Answer 1

尝试将标记放置到循环内具有任何 id 字段的对象，例如:

//before loop declare object
var markerMap = {}
...
//inside loop add marker to object with uuid (e.g mareker-1)
markerMap[ "marker-" + i ] = marker

然后将相同的 id 参数添加到 HTML 标记中

<ul class="marker-list">
   <li data-id="marker-1">Trigger Marker 1</li>
   <li data-id="marker-2">Trigger Marker 2</li>
</ul>

最后将事件添加到 li 元素(例如使用 jQuery)

 $(".marker-list").click( function() {
     var id = $(this).attr( 'data-id' );
     infoWindow.open( map, markerMap[ id ] );
 }); 

我没有测试这段代码。这只是一个想法。我希望你知道我的想法
