Question

我正在尝试将我的谷歌地图上的两个标记的纬度和经度用于某些文本框。我遵循了几个建议使用的指南：

google.maps.event.addListener(marker, 'dragend', function (event) {
document.getElementById("latbox").value = this.getPosition().lat();
document.getElementById("lngbox").value = this.getPosition().lng();
});

和

var lat = marker.getPosition().lat();
var lng = marker.getPosition().lng();

但是，我的文本框中没有填充任何内容。

谷歌地图代码（模糊了密钥，但它可以正常工作，因为我可以访问地图）：

<div class="content">
<div class="map" id="map"></div>
<script>
function initMap() {
var cpe = {lat: -20.269401 , lng: 57.497840};
var pl = {lat: -20.187042 , lng: 57.498377};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 11,
center: cpe
});
var marker = new google.maps.Marker({
position: cpe,
map:map,
draggable:true,
label: "P"


});

ar infowindow = new google.maps.InfoWindow({
content: "Pickup Point"
});

marker.addListener('mouseover', function() {
infowindow.open(map, marker);
});

var marker2 = new google.maps.Marker({
position: pl,
map:map,
draggable:true,
icon: 'http://maps.google.com/mapfiles/ms/icons/green-dot.png'

});


var infowindow2 = new google.maps.InfoWindow({
content: "Drop-Off Point"
});



marker2.addListener('mouseover', function() {
infowindow2.open(map, marker2);
});
}

google.maps.event.addListener(marker, 'dragend', function (event) {
document.getElementById("fromlat").value = this.getPosition().lat();
document.getElementById("fromlng").value = this.getPosition().lng();
});

google.maps.event.addListener(marker2, 'dragend', function (event) {
document.getElementById("tolat").value = this.getPosition().lat();
document.getElementById("tolng").value = this.getPosition().lng();
});
</script>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=*****&callback=initMap">
</script>

</div>

文本框：

enter code here
<div class="row">
<div class="col-sm-3">
<fieldset>
<input type="text" id="fromlat" name="fromlat" placeholder="Pickup Latitutde(Auto)"/>
</fieldset>
<fieldset>
<input type="text" id="fromlng" name="fromlng" placeholder="Pickup Longitude(Auto)"/>
</fieldset>
</div>
<div class="col-sm-3">
<fieldset>
<input type="text" id="tolat" name="tolat" placeholder="Destination Latitude(Auto)"/>
</fieldset>
<fieldset>
<input type="text" id="tolng" name="tolng" placeholder="Destination Longitude(Auto)"/>
</fieldset>
</div>

你只需要在initMap（）函数下定义事件函数这是脚本代码。请审核

<script>
var map;
function initMap() {
var cpe = {lat: -20.269401 , lng: 57.497840};
var pl = {lat: -20.187042 , lng: 57.498377};
map = new google.maps.Map(document.getElementById('map'), {
zoom: 11,
center: cpe
});
var marker = new google.maps.Marker({
position: cpe,
map:map,
draggable:true,
label: "P"


});
var infowindow = new google.maps.InfoWindow({
content: "Pickup Point"
});

marker.addListener('mouseover', function() {
infowindow.open(map, marker);
});

var marker2 = new google.maps.Marker({
position: pl,
map:map,
draggable:true,
icon: 'http://maps.google.com/mapfiles/ms/icons/green-dot.png'

});


var infowindow2 = new google.maps.InfoWindow({
content: "Drop-Off Point"
});



marker2.addListener('mouseover', function() {
infowindow2.open(map, marker2);
});

google.maps.event.addDomListener(marker, 'dragend', function (event) {
document.getElementById("fromlat").value = this.getPosition().lat();
document.getElementById("fromlng").value = this.getPosition().lng();
});

google.maps.event.addDomListener(marker2, 'drag', function (event) {
document.getElementById("tolat").value = this.getPosition().lat();
document.getElementById("tolng").value = this.getPosition().lng();
});


}
</script>
