如何从地图外触发谷歌地图标记

How to Trigger Google Maps Marker From Outside of Map

本文关键字：地图 谷歌 图标      更新时间：2023-09-26

我有这个HTML:

<ul class="google-map__trigger">
<li data-id="marker-1" class="google-map__trigger-item">Trigger Marker 1</li>
<li data-id="marker-2" class="google-map__trigger-item">Trigger Marker 2</li> 
</ul>
<div id="google-map" class="google-map"></div>

我有这个JS：

// Infowindow, latitude, longitude
var locations = [
    ['<div class="google-map__infowindow"><h4>Lervig Brygge</h4><p>Her ligger Lervig Brygge.</p></div>', 58.96746,5.765269],
    ['<div class="google-map__infowindow"><h4>Regn</h4><p>I denne rundkjøringen regner det. Det regner alltid i denne rundkjøringen. Det er litt av et naturfenomen!</p></div>', 58.96579,5.759518]
];
// Icons are located in this folder
var iconURLPrefix = '/_themes/prototype/graphics/icons/';
// Icons are named
var icons = [
    iconURLPrefix + 'location.svg',
    iconURLPrefix + 'weather-rain.svg',
]
// Map options
var map = new google.maps.Map(document.getElementById('google-map'),
    {
        zoom: 16,
        center: new google.maps.LatLng(58.966222, 5.762930),
        mapTypeControl: false,
        streetViewControl: false,
        panControl: false,
        scrollwheel: false,
        navigationControl: false,
        scaleControl: false,
        zoomControlOptions: {
        position: google.maps.ControlPosition.LEFT_BOTTOM
    }
});
var infowindow = new google.maps.InfoWindow({
    maxWidth: 200
});
var marker;
var markers = new Array();
var iconCounter = 0;
// Add the markers and infowindows to the map
for (var 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 : icons[iconCounter]
});
markers.push(marker);
google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
        infowindow.setContent(locations[i][0]);
        infowindow.open(map, marker);
    }
    })(marker, i));
    iconCounter++;
}
function AutoCenter() {
    // Create a new viewpoint bound
    var bounds = new google.maps.LatLngBounds();
        // Go through each...
        $.each(markers, function (index, marker) {
        bounds.extend(marker.position);
    });
    // Fit these bounds to the map
    map.fitBounds(bounds);
}
AutoCenter();

如何使用上面HTML中的列表从谷歌地图之外触发地图标记？我已经看到了解决这个问题的不同方法，但我还没有设法使它与我的代码一起工作。。。

感谢您的帮助！

Ref:如何在Google Maps V3上触发标记的onclick事件？

//using the index provided by jquery.each()  
$('.google-map__trigger-item').each(function(i){
    $(this).on('click', function(){
        google.maps.event.trigger(markers[i], 'click');
    });
});

或者，如果它们没有特定的顺序

//using your id data attribute
$('.google-map__trigger-item').each(function(){
    $(this).on('click', function(){
        var id = parseInt($(this).data('id').split('-')[1]) -1;
        google.maps.event.trigger(markers[id], 'click');
    });
});

更新2019：这是一个香草版本，添加了一些ES6语法糖。

[...document.querySelectorAll('.google-map__trigger-item')].map((el, i) => {
    el.addEventListener('click', () => {
        google.maps.event.trigger(markers[i], 'click');
    });
});

这样（不需要外部库）：

HTML

<ul class="google-map__trigger">
  <li data-id="marker-1" class="google-map__trigger-item">
      <a onclick="OpenInfowindowForMarker(1)">Trigger Marker 1</a></li>

Javascript

function OpenInfowindowForMarker(index) {
    google.maps.event.trigger(markers[index], 'click');
}
