我正在尝试在我的网站上添加 Google 地点自动完成功能。我在不使用实例化谷歌地图的情况下将搜索文本框与自动完成绑定时遇到问题。我想做的是，我想使用自动完成功能作为搜索字段上的文本建议。但遗憾的是，我见过的所有教程都将自动完成功能与谷歌地图一起使用。有什么办法可以解决这个问题吗？
提前致谢。
大家可以使用以下代码。
<!DOCTYPE html>
<html>
<head>
<link type="text/css" rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500">
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
<script>
var autocomplete;
function initialize() {
autocomplete = new google.maps.places.Autocomplete(
/** @type {HTMLInputElement} */(document.getElementById('autocomplete')),
{ types: ['geocode'] });
google.maps.event.addListener(autocomplete, 'place_changed', function() {
});
}
</script>
</head>
<body onload="initialize()">
<div id="locationField">
<input id="autocomplete" placeholder="Enter your address" onFocus="geolocate()" type="text"></input>
</div>
</body>
</html>
编辑：Google 地图现在需要 API 密钥 才能正常工作。
这是一个相当古老的线程，但谷歌现在需要一个API来支持他们所有基于地图的服务，我觉得代码示例可以简化一点。
head 元素内部（使用输入元素 id 属性更新代码）：
<script type="text/javascript">
function initAutocomplete() {
// Create the autocomplete object, restricting the search to geographical
// location types.
autocomplete = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */(document.getElementById('YOUR_INPUT_ELEMENT_ID')),
{types: ['geocode']});
// When the user selects an address from the dropdown, populate the address
// fields in the form.
autocomplete.addListener('place_changed', fillInAddress);
}
function fillInAddress() {
// Get the place details from the autocomplete object.
var place = autocomplete.getPlace();
}
</script>
在页面内确认您有一个文本输入，其 ID 属性与上述脚本匹配：
<input type="text" id="YOUR_INPUT_ELEMENT_ID" />
在正文标签结束之前添加此脚本（使用您自己的 API 密钥更新）：
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places&callback=initAutocomplete" async defer></script>
其他注意事项：
只需将 Secretkey 替换为您的 api 密钥即可。

<script>
var autocomplete;
function initialize() {
autocomplete = new google.maps.places.Autocomplete(
/** @type {HTMLInputElement} */
(document.getElementById('autocomplete')),
{ types: ['geocode'] }
);
google.maps.event.addListener(autocomplete, 'place_changed', function() {});
}
</script>
</head>
<div id="locationField">
<input id="autocomplete" name="location" placeholder="Enter your address" onFocus="geolocate()" type="text"></input>
</div>

它有相关方法的链接，包括
Autocomplete.getPlace()它还指出，“即使您没有显示地图，您也可以在任何应用程序中自由使用自动完成功能。我们所要求的只是，当您使用自动完成功能时，在文本字段下显示“由 Google 提供支持”徽标，而无需使用自动完成功能。地图”。

自 @PraveenHowpage 发布答案已有四年了。 API 已继续发展，但独立的示例很有吸引力，因此我在下面发布了更新版本，供那些仍在与自动完成斗争的人...
