在同一页面上添加多个Google地点实例

28

我想在同一个页面上包含两个Google Places自动完成实例。想要设置一个输入框用于接载位置,另一个输入框用于卸载位置。

我猜这与输入元素的ID有关,但即使我将其更改为类,它仍然无法工作。

这是我目前拥有的内容,它适用于第一个字段,但我无法弄清楚如何让第二个输入字段自动完成,或者甚至显示任何除了普通输入文本字段之外的迹象。

非常感谢任何帮助!

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true&libraries=places"></script>
<script type="text/javascript">
  var placeSearch,autocomplete;
  function initialize() {
    autocomplete = new google.maps.places.Autocomplete(document.getElementById('autocomplete'), { types: [ 'geocode' ] });
    google.maps.event.addListener(autocomplete, 'place_changed', function() {
      fillInAddress();
    });
  }
  function fillInAddress() {
    var place = autocomplete.getPlace();

    for (var component in component_form) {
      document.getElementById(component).value = "";
      document.getElementById(component).disabled = false;
    }

    for (var j = 0; j < place.address_components.length; j++) {
      var att = place.address_components[j].types[0];
      if (component_form[att]) {
        var val = place.address_components[j][component_form[att]];
        document.getElementById(att).value = val;
      }
    }
  }
</script>

HTML

<body onload="initialize()">
<form action="" method="post" name="theform" id="theform">
    <label>Pickup Location</label>
    <input type="text" name="PickupLocation" onfocus="geolocate()" placeholder="Enter your pickup location" id="autocomplete" autocomplete="off" />

    <label>Dropoff Location</label>
    <input type="text" name="DropoffLocation" onfocus="geolocate()" placeholder="Enter your dropoff location" id="autocomplete2" autocomplete="off" />
</form>

一种更动态的方法。您不需要初始化元素ID。

var inputs = document.getElementsByClassName('query');

var options = {
  types: ['(cities)'],
  componentRestrictions: {country: 'fr'}
};

var autocompletes = [];

for (var i = 0; i < inputs.length; i++) {
  var autocomplete = new google.maps.places.Autocomplete(inputs[i], options);
  autocomplete.inputId = inputs[i].id;
  autocomplete.addListener('place_changed', fillIn);
  autocompletes.push(autocomplete);
}

function fillIn() {
  console.log(this.inputId);
  var place = this.getPlace();
  console.log(place. address_components[0].long_name);
}
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places&key=AIzaSyC0Laj_Wk3kjFM-S8mYljc-WWCeesoDA_M"></script>

<input id="query-0" class="query" type="text"/>
<input id="query-1" class="query" type="text"/>
<input id="query-2" class="query" type="text"/>


实例化是动态的,但不是非常灵活。fillIn()需要适用于您自动完成的所有实例。在这种情况下我更喜欢明确地实例化一个命名变量以供额外使用。 - png
@NathanCH,我不太理解你的评论。你能提供一个jsfiddle帮助我理解吗?如果可以的话,我很乐意编辑我的答案以增加更多的灵活性。 - codeKonami

这只是个问题。
你使用了两个ID "autocomplete"和"autocomplete2"
但只初始化了ID为"autocomplete"的元素。
尝试添加以下代码到initialize()函数中。

Javascript

autocomplete2 = new google.maps.places.Autocomplete(document.getElementById('autocomplete2'), { types: [ 'geocode' ] });
google.maps.event.addListener(autocomplete2, 'place_changed', function() {
  fillInAddress();
});

啊,我竟然错过了这么愚蠢的事情!这个完美地解决了问题,谢谢你! - Colin Keany

这是我的解决方案,但需要使用jQuery。

var autocomplete = {};
  var autocompletesWraps = ['test', 'test2'];

  var test_form = { street_number: 'short_name', route: 'long_name', locality: 'long_name', administrative_area_level_1: 'short_name', country: 'long_name', postal_code: 'short_name' };
  var test2_form = { street_number: 'short_name', route: 'long_name', locality: 'long_name', administrative_area_level_1: 'short_name', country: 'long_name', postal_code: 'short_name' };

  function initialize() {

   $.each(autocompletesWraps, function(index, name) {
   
    if($('#'+name).length == 0) {
     return;
    }

    autocomplete[name] = new google.maps.places.Autocomplete($('#'+name+' .autocomplete')[0], { types: ['geocode'] });
     
    google.maps.event.addListener(autocomplete[name], 'place_changed', function() {
     
     var place = autocomplete[name].getPlace();
     var form = eval(name+'_form');

     for (var component in form) {
      $('#'+name+' .'+component).val('');
      $('#'+name+' .'+component).attr('disabled', false);
     }
     
     for (var i = 0; i < place.address_components.length; i++) {
      var addressType = place.address_components[i].types[0];
      if (typeof form[addressType] !== 'undefined') {
        var val = place.address_components[i][form[addressType]];
        $('#'+name+' .'+addressType).val(val);
      }
     }
    });
   });
  }

如何使克隆的元素正常工作,这些元素是在单击克隆按钮时加载的。 - Amit Sharma

我无法使Joseph的解决方案生效,因为第二个输入框仍会填充到第一个输入框中,所以这是基于他的答案进行了一些修改。

我在同一页上有两个地址表单,并且它们根据客户之前的选择动态显示,所以我首先创建了一个唯一的id,然后添加了常规字段。

<div id="<?php if( isset( $postcode_context ) && $postcode_context == "collection") { echo "collections-autocomplete-fields";} else {echo "autocomplete-fields";}?>" class="new-address-fields">
    <div class="fields">
    <div class="row form-group">
        <div class="col-xs-12 col-sm-6">
            <label for="Address1">Building Number/Name *</label>
            <input type="text" class="form-control field" name="Address1" id="street_number">
        </div>
        <div class="col-xs-12 col-sm-6">
            <label for="Address2">Address line 1 *</label>
            <input type="text" class="form-control field" name="Address2" id="route">
        </div>
    </div>
    <div class="row form-group">
        <div class="col-xs-12 col-sm-6">
            <label for="Address2">Address line 2</label>
            <input type="text" class="form-control field" name="Address2" id="route_two">
        </div>
        <div class="col-xs-12 col-sm-6">

    </div>
    <div class="row form-group">
        <div class="col-xs-12 col-sm-6">
            <label for="County">County</label>
            <input type="text" class="form-control field" name="County" id="administrative_area_level_1">

使用jQuery如下:
googlePlaces: function ($context) {
        var placeSearch, autocomplete;
        var componentForm = {
            street_number: 'short_name',
            route: 'long_name',

            country: 'long_name',
            postal_code: 'short_name'
        };

        var componentForm2 = {
            street_number: 'short_name',

            country: 'long_name',
            postal_code: 'short_name'
        };

        function initAutocomplete() {
            // Create the autocomplete object, restricting the search to geographical

            // When the user selects an address from the dropdown, populate the address
            // fields in the form.
            autocomplete.addListener('place_changed', fillInAddress);
            autocomplete2.addListener('place_changed', fillInAddress2);
        }

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

            for (var component in componentForm) {
                document.getElementById(component).value = '';
                document.getElementById(component).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++) {

我已经在这里写了一篇关于此的博客 -> https://lindarawson.com/adding-multiple-instances-of-google-places-on-same-page/

我采纳了您所有的答案,并制作了自己的答案。

在页面的加载函数中:


    $(document).ready(function() {
      var autocompletesWraps = ['facility_address', 'source_address'];
      createGeoListeners(autocompletesWraps);
    });

然后你有四个函数:


    function createGeoListeners(autocompletesWraps) {
            var options = {types: ['geocode']};
            var inputs = $('.autocomplete');
            var autocompletes = [];
            for (var i = 0; i < inputs.length; i++) {
                var autocomplete = new google.maps.places.Autocomplete(inputs[i], options);
                autocomplete.inputId = inputs[i].id;
                autocomplete.parentDiv = autocompletesWraps[i];
                autocomplete.addListener('place_changed', fillInAddressFields);
                inputs[i].addEventListener("focus", function() {
                    geoLocate(autocomplete);
                }, false);
                autocompletes.push(autocomplete);
            }
        }
        function fillInAddressFields() {
            $('.googleerror').removeClass('is-valid is-invalid');
            var place = this.getPlace();
            for (var i = 0; i < place.address_components.length; i++) {
                var addressType = place.address_components[i].types[0];
                var val = place.address_components[i].long_name;
                //console.log("address Type " + addressType + " val " + val + " pd " + this.parentDiv);
                $('#'+this.parentDiv).find("."+addressType).val(val);
                $('#'+this.parentDiv).find("."+addressType).attr('disabled', false);
            }
        }
        function geoLocate(autocomplete) {
            if (navigator.geolocation) {
                navigator.geolocation.getCurrentPosition(function(position) {
                    var geolocation = {
                        lat: position.coords.latitude,
                        lng: position.coords.longitude
                    };
                    var circle = new google.maps.Circle({
                        center: geolocation,
                        radius: position.coords.accuracy
                    });
                    autocomplete.setBounds(circle.getBounds());
                });
            }
        }
        function gm_authFailure() { 
            $('.gm-err-autocomplete').addClass('is-invalid');
            swal("Error","There is a problem with the Google Maps or Places API","error");
        };


希望这能帮到你。

几乎对我有用,但是来自两个字段的搜索结果都显示在表单1上。 - Cristiano Maia

<script type="text/javascript" >
function initAutocomplete() {
var input = document.getElementById('source');
var searchBox = new google.maps.places.SearchBox(input);
                            document.write(searchBox)


var input = document.getElementById('destination');
var searchBox1 = new google.maps.places.SearchBox(input);
                            document.write(searchBox1)
}
</script>

这个解决方案可行,但有一个问题:

var theFields = ['field1','field2','field3','field4'];
function initialize() {
// Create the autocomplete object, restricting the search
// to geographical location types.
 for (i=0;i<cityFields.length; i++){

      autocomplete = new google.maps.places.Autocomplete((document.getElementById(cityFields[i])),
  { types: ['geocode'] })
  }

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

然而,唯一的问题是如果页面上不存在field1,则field2将无法加载脚本。例如,在我的情况下,前两个字段存在于一个页面上,另外两个字段存在于另一个页面上,但脚本被添加到页眉(WordPress页眉)中...

我在一个页面上有多个自动完成的问题, 一个组件创建了自动完成,而我需要调用两次。
问题是:自动完成只对第一个输入有效,而不是第二个。
解决方法是:将“uniqueId”作为属性传递给组件,在组件中,在“place_changed”事件侦听器中解决。
    const input = document.getElementById(uId);
    let autocomplete = new window.google.maps.places.Autocomplete(input);
    autocomplete.setComponentRestrictions({ "country": "il" });
    autocomplete.addListener("place_changed", () => { handlePlaceChange(autocomplete) })

我现在很忙,如果有人需要更多信息,请联系我shankehat@gmail.com
