ユーザーが2つの都市を入力できるようにし、指定された入力の場所を表示するこのコードがあります。しかし、私が欲しいのは、最初の都市から他の都市への方向も示すことです。どうやってするか?
これが私の練習コードです:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 100% }
</style>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=AIzaSyBQ8OCC8En5vNHod25Ov3Qs5E1v7NPRSsg&sensor=true">
</script>
<script type="text/javascript">
var geocoder;
var map;
function initialize1() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 100.644),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
}
function initialize() {
// add mapOptions here to the values in the input boxes.
var mapOptions = {
center: new google.maps.LatLng(-34.397, 100.644),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
geocoder = new google.maps.Geocoder();
addAddress(document.getElementById('from').value);
addAddress(document.getElementById('to').value);
}
function addAddress(place) {
var address = place;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
</script>
</head>
<body>
From: <input id="from" type="text" name="From"><br>
To: <input id="to" type="text" name="To"><br>
<button type="button" onclick="initialize()">View example (map-simple.html)</button>
<div id="map_canvas" style="width:100%; height:100%"></div>
</body>
</html>
ありがとう
