谷歌距离计算器和自动完成

我正在尝试使用谷歌地图和自动完成做一些工作。我采用了谷歌距离脚本，并尝试将谷歌的自动完成功能与它集成在一起。距离计算和路线方向工作正常。但是我在开始和结束输入字段中的自动完成失败了。如果我在结束和开始字段中手动输入位置，它可以工作，但没有自动完成谷歌工作。

更改

     <script type="text/javascript"
     src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>

自

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=false&libraries=places"></script>

后

map = new google.maps.Map(document.getElementById('map_canvas'),
        mapOptions);

加

    //Find From location    
    var fromText = document.getElementById('start');
    var fromAuto = new google.maps.places.Autocomplete(fromText);
    fromAuto.bindTo('bounds', map);
    //Find To location
    var toText = document.getElementById('end');
    var toAuto = new google.maps.places.Autocomplete(toText);
    toAuto.bindTo('bounds', map);
    //

您可以将此代码用于国家/地区限制：

var autocomplete = new google.maps.places.Autocomplete(
    input,
    // Options
    {
        types: ['(cities)'],
        componentRestrictions: {country: 'au'}
    }
);
autocomplete.bindTo('bounds', map);

我知道我回复晚了，但这也会帮助其他人。

$url = 'https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=Hyderabad+Telangana+India&destinations=Mumbai+Maharashtra+India';
// Get the data from Google Maps API
$json = file_get_contents($url);
// Convert it from JSON to PHP array
$result = json_decode($json, true);
$mi = $result['rows'][0]['elements'][0]['distance']['text'];
echo $km = $mi*1.60934." KM <br/>";
echo $result['rows'][0]['elements'][0]['duration']['text'];
