Question

我在我的页面上使用Google Maps API，该页面要求用户填写“当前地址”和“新地址”。

我可以让自动完成工作在第一个地址，但它不适用于第二个地址，我做了很多研究并查看了stackoverflow上的simular帖子，但我找不到任何有同样问题的人。< / p>

这是我的代码;

<div id="locationField">
    <input id="autocomplete" placeholder="Start typing your address" onFocus="geolocate()" type="text"></input>
</div>

<div id="addressone">
    <input type="text" id="street_number" name="street_number"></input>
    <input type="text" id="route" name="street_name"></input>
    <input type="text" id="locality" name="town_city"></input>
    <input type="text" id="postal_code" name="postcode"></input>
    <input type="text" id="country" name="country"></input>
</div>

<div id="locationField2">
    <input id="autocomplete2" placeholder="Start typing your address" onFocus="geolocate()" type="text"></input>
</div>

<div id="addresstwo">
    <input type="text" id="street_number2" name="street_number2"></input>
    <input type="text" id="route2" name="street_name2"></input>
    <input type="text" id="locality2" name="town_city2"></input>
    <input type="text" id="postal_code2" name="postcode2"></input>
    <input type="text" id="country2" name="country2"></input>
</div>

        var addressType = place.address_components[i].types[0];
        if (componentForm[addressType]) {
          var val = place.address_components[i][componentForm[addressType]];
          document.getElementById(addressType).value = val;
        }
      }

    // [END region_fillform]

您需要处理两个自动完成输入。以下是fillInAddress的通用版本，它将处理多个自动完成对象，其中包含具有唯一扩展名的字段（表单第二个版本中的“2”）：

function fillInAddress(autocomplete, unique) {
    // Get the place details from the autocomplete object.
    var place = autocomplete.getPlace();

    for (var component in componentForm) {
        if(!!document.getElementById(component + unique)){
            document.getElementById(component + unique).value = '';
            document.getElementById(component + unique).disabled = false;
        }
    }

    // Get each component of the address from the place details
    // and fill the corresponding field on the form.
    for (var i = 0; i < place.address_components.length; i++) {
        var addressType = place.address_components[i].types[0];
        if (componentForm[addressType] && document.getElementById(addressType + unique)) {
            var val = place.address_components[i][componentForm[addressType]];
            document.getElementById(addressType + unique).value = val;
        }
    }
}

这样称呼：

// Create the autocomplete object, restricting the search to geographical
// location types.
autocomplete = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */
(document.getElementById('autocomplete')), {
    types: ['geocode']
});

// When the user selects an address from the dropdown, populate the address
// fields in the form.
autocomplete.addListener('place_changed', function () {
    fillInAddress(autocomplete, "");
});

// Create the second autocomplete object, restricting the search to geographical
// location types.
autocomplete2 = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */
(document.getElementById('autocomplete2')), {
    types: ['geocode']
});
autocomplete2.addListener('place_changed', function () {
    fillInAddress(autocomplete2, "2");
});

这就像一个魅力：）

感谢jQuery。

function initMultiComplete() {
   jQuery('.maps-complete').each(function(){

    var id = jQuery(this).prop('id');
    var $this = jQuery(this);
    var parent = jQuery(this).parent('div');

    var jautocomplete = new google.maps.places.Autocomplete(document.getElementById(id), {types: ['geocode']});

    jautocomplete.addListener('place_changed', function ()    {

        var place = jautocomplete.getPlace();
        var address = $this.val();
        var lat = place.geometry.location.lat();
        var lng = place.geometry.location.lng();

        jQuery( '.maps-autocomplete-lat', parent ).val(lat);
        jQuery( '.maps-autocomplete-lng', parent ).val(lng);

    });

});
}

脚本将initMultiComplete作为回调调用，并加载w / async defer：

https://maps.googleapis.com/maps/api/js?key=YOUR_KEY&libraries=places&callback=initMultiComplete

这是一个古老的问题，但我认为我会将此解决方案发布到此，以防将来对其他人有所帮助。我的解决方案处理页面上任意数量的地图api自动填充字段。您需要使用班级名称标记所有自动填充字段，在我的情况下，我使用了班级名称＆＃34;地址＆＃34;。

现在抓住字段集合：

function addListener(el) {
  var autocomplete = new google.maps.places.Autocomplete(el);

  google.maps.event.addListener(autocomplete, 'place_changed', function ()    {
 // Do whatever you want in here e.g.
 // var place = autocomplete.getPlace();
  });
}

调用一个名为＆＃34; addListener＆＃34;

的函数

select
  c.*,
  m.multi_company
from
  #1 c
  join
  (
    select
      customer,
      case
        when count(*) > 1 then 1
        else 0
      end as multi_company
    from #1
    group by customer
  ) m on c.customer = m.customer;

因为它是一个集合，您应该能够向页面添加任意数量的自动填充字段。虽然很自然，但是如果您的页面上没有自动填充字段，则应检查集合上的未定义。

Google Maps API会在同一页面上自动填充第二个地址字段
