我想使用谷歌地图从2点建立距离计算器。但输出不起作用。我没有得到那些2点的距离和持续时间 这是我的javascript代码。
var source, destination;
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
google.maps.event.addDomListener(window, 'load', function () {
new google.maps.places.SearchBox(document.getElementById('autocomplete'));
new google.maps.places.SearchBox(document.getElementById('autocomplete1'));
directionsDisplay = new google.maps.DirectionsRenderer({ 'draggable': true });
});
function GetRoute() {
var mumbai = new google.maps.LatLng(18.9750, 72.8258);
var mapOptions = {
zoom: 7,
center: mumbai
};
map = new google.maps.Map(document.getElementById('dvMap'), mapOptions);
directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById('dvPanel'));
//*********DIRECTIONS AND ROUTE**********************//
source = document.getElementById("autocomplete").value;
destination = document.getElementById("autocomplete1").value;
var request = {
origin: source,
destination: destination,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
//*********DISTANCE AND DURATION**********************//
var service = new google.maps.DistanceMatrixService();
service.getDistanceMatrix({
origins: [source],
destinations: [destination],
travelMode: google.maps.TravelMode.DRIVING,
unitSystem: google.maps.UnitSystem.METRIC,
avoidHighways: false,
avoidTolls: false
}, function (response, status) {
if (status == google.maps.DistanceMatrixStatus.OK && response.rows[0].elements[0].status != "ZERO_RESULTS") {
var distance = response.rows[0].elements[0].distance.text;
var duration = response.rows[0].elements[0].duration.text;
var dvDistance = document.getElementById("dvDistance");
dvDistance.innerHTML = "";
dvDistance.innerHTML += "Distance: " + distance + "<br />";
dvDistance.innerHTML += "Duration:" + duration;
} else {
alert("Unable to find the distance via road.");
}
});
}
这是我的HTML代码
<div id="fifth">
<div class="row">
<p><b>Step 5:Locations Details</b></p>
</div>
<div class="row">
<div class="col-md-3">
<input type="text" class="form-control" id="autocomplete" placeholder="Pick-up Location">
</div>
<div class="col-md-3">
<input type="text" class="form-control" id="autocomplete1" placeholder="Drop-off Location">
</div>
<div class="col-md-3">
<input type="button" class="form-control" value="Get Distance" onclick="GetRoute()">
</div>
</div>
<div class="row">
<table>
<tr>
<td colspan="2">
<div id="dvDistance"></div>
</td>
</tr>
<tr>
<td>
<div id="dvMap" style="width: 500px; height: 500px"></div>
</td>
<td>
<div id="dvPanel" style="width: 500px; height: 500px"></div>
</td>
