我在地图上有一堆传单标记.每个标记都保存在阵列标记中.标记是动态创建的(在ajax调用期间).

var markers = [];
.
.
var marker = L.marker([mar.lat, mar.lng], {
  // ...build the marker...
}
marker._leaflet_id = mar.id; // give the marker an id corresponding to the id of its corresponding div
var myHoverIcon = L.icon({
  iconUrl: mar.imgUrl,
  iconSize: [40, 40],
  popupAnchor: [0, 0]
});
marker.on('click', function(e) {
  alert('Marker clicked!');
  marker.setIcon(myHoverIcon);
});
.
.
markers.push(marker);

每个标记具有对应于特定div的id(存储在div上的data-mess_id中).计划是在单击Feed中相应的div时更改标记的图标.

$('#feed').on('mouseover', '.message', function() {
  var cssid = $(this).attr('data-mess_id').toString();
  var baz = $.grep(markers, function(m) {
    return (m._leaflet_id == cssid);
  });
  baz[0].trigger('click');   // doesn't work 
  alert(baz[0].getLatLng()); // does work

  // this also does not work:
  var myHoverIcon = L.icon({
    iconUrl: baz[0].imgUrl,
    iconSize: [40, 40],
    popupAnchor: [0, 0]
  });
  baz[0].setIcon(myHoverIcon);

});

除了最后一点,它一切正常.我只是无法触发标记上的点击事件.我肯定有正确的标记,因为baz [0] .getLatLng()正在工作.但是baz [0] .trigger(‘click’)不起作用.

我尝试动态创建一个新图标(myHoverIcon),但它不起作用.

如何在标记上触发点击事件？

还有其他方法可以更改标记图标吗？

解决方法:

要模拟鼠标单击,您可以在标记上使用fire方法(从Evented.fire继承)：

marker.fire('click');

还有一个演示

var map = L.map('map').setView([0, 0], 12);

var icon = L.icon({
  iconUrl: 'http://leafletjs.com/examples/custom-icons/leaf-green.png'
});
var marker = L.marker([0, 0], {icon: icon})
  .addTo(map);
  
  
var myHoverIcon = L.icon({
  iconUrl: 'http://leafletjs.com/examples/custom-icons/leaf-red.png'
});
  
  
marker.on('click', function(e) {
  marker.setIcon(myHoverIcon);
});

document.querySelector('button').addEventListener('click', function() {
  marker.fire('click');
});

html, body {
  height: 100%;
  margin: 0;
}
#map {
  width: 100%;
  height: 100%;
}

button {position: absolute; left:10 px; top: 70px;}
