我有使用谷歌距离矩阵API计算到另一个地方的距离的代码,但是免费的每个查询仅限100个元素。所以我使用循环代码(例如元素)来编写解决问题的代码,我的代码是PHP,javascript,并且我解析来自MySql的纬度和经度数据。有人知道我的代码有些错误吗?因为如果单击“计算”按钮,它就不会显示任何内容。 Actualy我修改了这个URL https://google-developers.appspot.com/maps/documentation/javascript/examples/distance-matrix的代码,这是我的代码:
function hitung (){
service = new google.maps.DistanceMatrixService();
for (m = 0 ; m < l-80 ; m++ ){
asal = originarray[m];
for (n = 0 ; n < l-80 ; n++ ){
tujuan = destarray [n];
calculateDistances();
}
}
}
function calculateDistances() {
//var s = 0;
//for (m = 0 ; m < l-80 ; m++ ){
// asal = originarray[m];
//for (n = 0 ; n < l-80 ; n++ ){
//servicearray[s] = new google.maps.DistanceMatrixService();
//tujuan = destarray [n];
service.getDistanceMatrix(
{
//origins: [origin1, origin2],
// destinations: [destinationA, destinationB],
origins: asal,
destinations: tujuan,
//origins: originarray,
//destinations: destarray,
travelMode: google.maps.TravelMode.DRIVING,
unitSystem: google.maps.UnitSystem.METRIC,
avoidHighways: false,
avoidTolls: false
}, callback);
// s++;
//}
// }
}
function callback(response, status) {
if (status != google.maps.DistanceMatrixStatus.OK) {
alert('Error was: ' + status);
} else {
var origins = response.originAddresses;
var destinations = response.destinationAddresses;
var outputDiv = document.getElementById('outputDiv');
//outputDiv.innerHTML = '';
// deleteOverlays();
for (var i = 0; i < origins.length; i++) {
var results = response.rows[i].elements;
// addMarker(origins[i], false);
for (var j = 0; j < results.length; j++) {
// addMarker(destinations[j], true);
outputDiv.innerHTML += origins[i] + ' to ' + destinations[j]
+ ': ' + results[j].distance.text + ' in '
+ results[j].duration.text + '<br>';
}
}
}
}
function addMarker(location, isDestination) {
var icon;
if (isDestination) {
icon = destinationIcon;
} else {
icon = originIcon;
}
geocoder.geocode({'address': location}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
bounds.extend(results[0].geometry.location);
map.fitBounds(bounds);
var marker = new google.maps.Marker({
map: peta,
position: results[0].geometry.location,
icon: icon
});
markersArray.push(marker);
} else {
alert('Geocode was not successful for the following reason: '
+ status);
}
});
}
function deleteOverlays() {
if (markersArray) {
for (i in markersArray) {
markersArray[i].setMap(null);
}
markersArray.length = 0;
}
}
