I have to do a draggable marker and its coordinates should be displayed in fields. It will be a part of a contact form in PHP. I created a draggable marker, help me what to do now.

var marker = L.marker(new L.LatLng(53.471, 18.744), {
draggable: true
}).addTo(map);

这是 Google Maps API 中的示例，我需要在 Leaflet 中使用相同的示例.

Here is example in Google Maps API, I need the same in Leaflet.

推荐答案

你应该使用L.Marker的dragend事件，所以你知道拖动已经结束，然后使用L的getLatLng方法获取标记的坐标.标记.获取这些内容后，您可以将它们分配给文本输入的值.

You should use the dragend event of L.Marker, so you known dragging has ended, then get the coordinates of the marker by using the getLatLng method of L.Marker. When you've fetched those you can assign them to the values of your text inputs.

marker.on('dragend', function (e) {
    document.getElementById('latitude').value = marker.getLatLng().lat;
    document.getElementById('longitude').value = marker.getLatLng().lng;
});
