如何添加Google地图自动填充搜索框？

时间：2012-12-03 18:48:46

标签： javascript google-maps-api-3 autocomplete

我正在尝试向网站添加Google自动填充搜索框，以便用户可以尽可能轻松地搜索地址。

我的问题是，我在这里看到了很多问题以及关于这个和一些教程的Google Maps Javascript API v3，但他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，遗憾的是我无法确定API的哪些部分与此相关，我所看到的每个示例都包含大量用于映射的JS 。

我如何才能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>

使用Javascript：

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

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

您可以在http://www.redwoodtransit.org找到示例。

要立即使用Google Maps / Places API，您需要使用API​​密钥。因此，API URL将从

更改 
<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>

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网络服务准备好API密钥。将其替换为以下脚本文件。 

<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文件看起来像这样。

    // 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);
}

遵循以下代码。

将此添加到您的TS文件。

在班级顶部声明这一点。 

declare var google;

为Map和输入声明视图子级。

@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上调用方法。

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

这是 HTML代码。请根据需要进行修改。

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


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


        <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">
                    <input type="text" #autoCompleteInput class="location-input" [(ngModel)]="search_location" placeholder="Search location">
                    <span class="location-icon" (click)="getCurrentLocation()">
                        <img src="../../assets/images/location-icon.svg" alt="">
                    </span>
                </div>

                <button type="button" class="location-search-btn" (click)="goToVendorSearch()">
                    <i class="fa fa-angle-right"></i>
                </button>

            </div>
        </div>

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。我还使用了一个角度函数来显示当前位置并建议城市名称密码等... -添加google 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component.ts文件上创建函数。
导入这些文件 

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

initLocationAutocomplete() {
let autocomplete, place, model;
const getLocation = () => {
place = autocomplete.getPlace();
if (place && (place.formatted_address || place.name)) {  
// if you want set value in your form controls like 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);
}

所以我一直在玩这个游戏，看来您需要同时激活地点和js maps api。然后使用以下命令：

HTML：

HEREDOC

JS：

add_shortcode('recentvideos' , 'printrecenttv');

function printrecenttv(){
    $recent_posts = wp_get_recent_posts(array(
        'numberposts' => 4, // Number of recent posts thumbnails to display
        'post_status' => 'publish', // Show only the published posts
        'post_type'  => "tv" //Show only Videos
    ));
    foreach($recent_posts as $post) : 
        $perm = get_permalink($post['ID']);
        $imgurl = get_the_post_thumbnail_url($post['ID'], 'full');
return <<<HTML
     <div class="videoposter">
        <a class="posterlink" href="$perm">
                <img class="posterimg" src="$imgurl">
            </a>
    </div>
HTML;
     endforeach; wp_reset_query();
}
