Question

我想将google draggable地图标记的地址传递到字段中，然后将其提交到mysql数据库的列中。我发现下面的代码正是我想要的，但我想把＃34;最贴近的匹配地址＆＃34;输入字段内的结果。我怎样才能做到这一点？

<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder = new google.maps.Geocoder();

function geocodePosition(pos) {
 geocoder.geocode({
latLng: pos
}, function(responses) {
if (responses && responses.length > 0) {
  updateMarkerAddress(responses[0].formatted_address);
} else {
  updateMarkerAddress('Cannot determine address at this location.');
}
});
}

function updateMarkerStatus(str) {
document.getElementById('markerStatus').innerHTML = str;
}

function updateMarkerPosition(latLng) {
document.getElementById('info').innerHTML = [
latLng.lat(),
latLng.lng()
].join(', ');
}

function updateMarkerAddress(str) {
document.getElementById('address').innerHTML = str;
}

function initialize() {
var latLng = new google.maps.LatLng(-34.397, 150.644);
var map = new google.maps.Map(document.getElementById('mapCanvas'), {
zoom: 8,
center: latLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
position: latLng,
title: 'Point A',
map: map,
draggable: true
});

// Update current position info.
updateMarkerPosition(latLng);
geocodePosition(latLng);

// Add dragging event listeners.
google.maps.event.addListener(marker, 'dragstart', function() {
updateMarkerAddress('Dragging...');
});

google.maps.event.addListener(marker, 'drag', function() {
updateMarkerStatus('Dragging...');
updateMarkerPosition(marker.getPosition());
});

google.maps.event.addListener(marker, 'dragend', function() {
updateMarkerStatus('Drag ended');
geocodePosition(marker.getPosition());
});
}

// Onload handler to fire off the app.
google.maps.event.addDomListener(window, 'load', initialize);
</script>

<body>

#mapCanvas {width: 500px;height: 400px;float: left;}
#infoPanel {float: left;margin-left: 10px;}
#infoPanel div {margin-bottom: 5px;}
</style>

<div id="mapCanvas"></div>
<div id="infoPanel">
<b>Marker status:</b>
<div id="markerStatus"><i>Click and drag the marker.</i></div>
<b>Current position:</b>
<div id="info"></div>
<b>Closest matching address:</b>

变化：

<div id="address"></div>

function updateMarkerAddress(str) {
  document.getElementById('address').innerHTML = str;
}

要：

<input id="address" />

function updateMarkerAddress(str) {
    document.getElementById('address').value = str;
}

如何将可拖动的谷歌地图标记的地址传递到输入字段？
