我的问题是，我在这里查看了很多问题，以及谷歌地图Javascript API v3，关于这一点和一些教程，但它们都将自动完成功能与在嵌入式谷歌地图上映射功能捆绑在一起

我不需要直观地映射位置，我现在只需要autocomplete框，不幸的是我无法确定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

如何仅添加自动完成输入功能？

使用谷歌地图JavaScript API和places库在网页中实现谷歌地图自动完成搜索框

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);

函数initMap（）{
var input=document.getElementById（'searchInput'）；
var autocomplete=new google.maps.places.autocomplete（输入）；

从这里可以找到完整的指南、源代码和实时演示-

要使用Google Maps/Places API，您需要使用API密钥。因此，API URL将从

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

我在这里使用jQuery获取输入的文本，并将所有代码包装在$（document）.ready（）中。确保您已经为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>


函数初始化（）{
新的google.maps.places.Autocomplete(
（document.getElementById（'autocomplete'））{
类型：['geocode']
});
}
初始化（）；
要获得纬度和经度，也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>

          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);
