我正在尝试将 Google 自动完成搜索框添加到网站，以便用户可以尽可能轻松地搜索地址。

我的问题是，我在这里查看了很多问题以及有关此内容的 Google Maps Javascript API v3 和一些教程，但它们都将自动完成功能捆绑在一起，并将其映射到嵌入式 Google 地图上。

我不需要直观地映射位置，我现在只需要自动完成框，不幸的是我无法确定 API 的哪些部分与此相关，并且我查看的每个示例都包含大量用于映射的 JS。

我怎样才能只添加自动完成输入功能？

可以消除此代码的很大一部分。

HTML 摘录：

<head>
  ...
  <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
  ...
</head>
<body>
  ...
  <input id="searchTextField" type="text" size="50">
  ...
</body>

Javascript：

function initialize() {
  var input = document.getElementById('searchTextField');
  new google.maps.places.Autocomplete(input);
}

google.maps.event.addDomListener(window, 'load', initialize);

要获得纬度和经度，您可以使用以下简单代码：

<html>
<head>
    <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places"></script>
    <script>
        function initialize() {
          var input = document.getElementById('searchTextField');
          var autocomplete = new google.maps.places.Autocomplete(input);
            google.maps.event.addListener(autocomplete, 'place_changed', function () {
                var place = autocomplete.getPlace();
                document.getElementById('city2').value = place.name;
                document.getElementById('cityLat').value = place.geometry.location.lat();
                document.getElementById('cityLng').value = place.geometry.location.lng();
            });
        }
        google.maps.event.addDomListener(window, 'load', initialize);
    </script>
</head>
<body>
    <input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on" runat="server" />  
    <input type="hidden" id="city2" name="city2" />
    <input type="hidden" id="cityLat" name="cityLat" />
    <input type="hidden" id="cityLng" name="cityLng" />

现在要使用 Google Maps/Places API，您需要使用 API 密钥。所以 API URL 将从

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&signed_in=true&libraries=places"></script>

到

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

    </head>
    <body>
        <label for="locationTextField">Location</label>
        <input id="locationTextField" type="text" size="50">

        <script>
            function init() {
                var input = document.getElementById('locationTextField');
                var autocomplete = new google.maps.places.Autocomplete(input);
            }

使用 Google Maps JavaScript API 和地点库在网页中实现 Google Maps 自动完成搜索框。

HTML

<input id="searchInput" class="controls" type="text" placeholder="Enter a location">

JavaScript

<script>
function initMap() {
    var input = document.getElementById('searchInput');
    var autocomplete = new google.maps.places.Autocomplete(input);
}
</script>

所以我一直在玩这个，看来你需要激活地方和 js maps api。然后使用以下内容：

HTML：

<input id="searchTextField" type="text" size="50">
<input id="address" name="address" value='' type="hidden" placeholder="">

JS：

<script>
function initMap() {
  var input = document.getElementById('searchTextField');
  var autocomplete = new google.maps.places.Autocomplete(input);
  autocomplete.addListener('place_changed', function() {
    var place = autocomplete.getPlace();
    document.getElementById("address").value = JSON.stringify(place.address_components);
  });
}
</script>

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places&callback=initMap" async defer></script>

按照下面的代码。

将此添加到您的 TS 文件中。

声明这一点，你班上的佼佼者。

declare var google;

声明 Map 的子视图和输入。

@ViewChild('mapElement', {static: true}) mapNativeElement: ElementRef;
@ViewChild('autoCompleteInput', {static: true}) inputNativeElement: any;

此方法在 ngOnInit() 事件或 ngAfterViewInit() 事件上运行。

autoComplete() {
    const map = new google.maps.Map(this.mapNativeElement.nativeElement, {
      center: {lat: -33.8688, lng: 151.2093},
      zoom: 7
    });

    const infowindow = new google.maps.InfoWindow();
    const infowindowContent = document.getElementById('infowindow-content');

    infowindow.setContent(infowindowContent);

    const marker = new google.maps.Marker({
      map: map,
      anchorPoint: new google.maps.Point(0, -29)
    });
    const autocomplete = new google.maps.places.Autocomplete(this.inputNativeElement.nativeElement as HTMLInputElement);
    autocomplete.addListener('place_changed', () => {
      infowindow.close();
      marker.setVisible(false);
      const place = autocomplete.getPlace();

      let cus_location = {
        lat: place.geometry.location.lat(),
        long: place.geometry.location.lng()
      }

      console.log('place data :................', cus_location); 
      localStorage.setItem('LOC_DATA', this.helper.encryptData(cus_location));

      if (!place.geometry) {
        // User entered the name of a Place that was not suggested and
        // pressed the Enter key, or the Place Details request failed.
        window.alert('No details available for input: ' + place.name );
        return;
      }

      if (place.geometry.viewport) {
        map.fitBounds(place.geometry.viewport);
      } else {
        map.setCenter(place.geometry.location);
        map.setZoom(17);  // Why 17? Because it looks good.
      }

      marker.setPosition(place.geometry.location);
      marker.setVisible(true);
      let address = '';
      if (place.address_components) {
        address = [
          (place.address_components[0] && place.address_components[0].short_name || ''),
          (place.address_components[1] && place.address_components[1].short_name || ''),
          (place.address_components[2] && place.address_components[2].short_name || '')
        ].join(' ');
      }

      if(infowindowContent){
        infowindowContent.children['place-icon'].src = place.icon;
        infowindowContent.children['place-name'].textContent = place.name;
        infowindowContent.children['place-address'].textContent = address;
      } 

      infowindow.open(map, marker);
    });

  }

在 ngAfterViewInit 上调用该方法。

ngAfterViewInit(): void {
    this.autoComplete();
  }

这是HTML 代码。请根据您的需要进行修改。

<ion-content fullscreen>
    <div class="location-col">


        <div class="google-map">
            <!-- <img src="../../assets/images/google-map.jpg" alt=""> -->

        <div class="location-info">
            <h2>Where is your car located?</h2>
            <p>Enter address manually or click location detector icon to use current address.</p>
            <div class="form-group">

                <div class="location-row">

我目前正在使用 Google API 来检索用户在表单/输入中输入的位置。我还使用了显示当前位置并建议城市名称密码等的角度函数...... - 添加谷歌 API index.html。
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=xxxxxxxx&libraries=geometry,places"></script>
- 在输入框中添加 id 以获取字符串和字符。
<input id="autocomplete" type="text"(keydown)="checkAddress($event.target.value)">
- 并在您的 component.ts 文件上创建函数。
导入这些文件

import * as _ from 'lodash';
declare var google: any;

 checkAddress(value) {
    if (!value) {
      this.model.location = _.cloneDeep(value);
      this.rfpForm.controls['location'].setValue(this.model.location);
    }
  }

initLocationAutocomplete() {
    let autocomplete, place;
    const getLocation = () => {
        place = autocomplete.getPlace();
        if (place && (place.formatted_address || place.name)) {  
            // if you want set value in your form controls like this
            this.model.location = _.cloneDeep(place.formatted_address || place.name);
            // YourFormName.controls['location'].setValue(this.model.location);
            // YourFormName.controls['location']['_touched'] = true;
        }
    };
    autocomplete = new google.maps.places.Autocomplete((document.getElementById('autocomplete')), { types: ['geocode'] });
    autocomplete.addListener('place_changed', getLocation);
}

我在这里使用 jQuery 来获取输入的文本并将所有代码包装在 $(document).ready() 中。确保您已为 Google Places API Web 服务准备好 API 密钥。在下面的脚本文件中替换它。 

<input type="text" id="location">
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=[YOUR_KEY_HERE]&libraries=places"></script>
<script src="javascripts/scripts.js"></scripts>

使用脚本文件加载自动完成类。您的 scripts.js 文件将如下所示。

    // scripts.js custom js file
$(document).ready(function () {
   google.maps.event.addDomListener(window, 'load', initialize);
});

function initialize() {
    var input = document.getElementById('location');
    var autocomplete = new google.maps.places.Autocomplete(input);
}
