Question

好的，我在测试网站上设置了地图和自动填充字段。

我的目标是让用户在字段中输入他/她的地址，然后当他/她点击确认根据提供的信息确定离他们最近的商店时。

我对每个商店都有lat / long，并且在自动完成的帮助下，我现在有了lat / long的用户地址，但是当我使用文档中提供的computeDistanceBetween方法时，我得到NaN而不是期望的结果。< / p>

以下是指向测试网站的链接，以获取相关信息 - http://dev.touch-akl.com/map/

以下是我到目前为止所尝试的内容

    //----------------------------------------------------------------
    //--- Search Box -------------------------------------------------

    var input = document.getElementById('address');
    var $confirm = $('#confirm');

    var options = {
       types: ['geocode'],
       componentRestrictions: {country: 'nz'}//Turkey only
    };        

    var autocomplete = new google.maps.places.Autocomplete(input,options);
    autocomplete.bindTo('bounds', map);

    $confirm.click(function(){

        var _street = $('#address').val();
        var place = autocomplete.getPlace();
        var _coordinates = place.geometry.location.toString();
        var _delivery = _coordinates.substring(1, _coordinates.length - 1);
        var _kCord = '-36.874694,174.735292';
        var _pCord = '-36.858317,174.782284'

        console.log(_coordinates);
        console.log(_delivery);

        console.log(google.maps.geometry.spherical.computeDistanceBetween(_pCord, _delivery));
        console.log(google.maps.geometry.spherical.computeDistanceBetween(_kCord, _delivery));


    });

google.maps.geometry.spherical.computeDistanceBetween要求您提供两个google.maps.LatLng对象，而您正在使用字符串，这将无效。以下应该......

$confirm.click(function(){
    var _street = $('#address').val();
    var place = autocomplete.getPlace();
    var _coordinates = place.geometry.location; //a google.maps.LatLng object
    var _kCord = new google.maps.LatLng(-36.874694, 174.735292);
    var _pCord = new google.maps.LatLng(-36.858317, 174.782284);

    console.log(_coordinates);

    console.log(google.maps.geometry.spherical.computeDistanceBetween(_pCord, _coordinates));
    console.log(google.maps.geometry.spherical.computeDistanceBetween(_kCord, _coordinates));
});

使用谷歌地图computeDistanceBetween获取最近的位置返回NaN
