Javascript 如何使用自动完成谷歌地图没有地图，但自动建议的地方只？

我有一个输入表单，用户应该能够看到与他/她键入的单词相关的位置建议。我通过谷歌找到的解决方案是使用谷歌地图自动完成。但问题是，我根本不需要地图。我想要的只是当用户在我自己的输入框中键入内容时提供建议的函数。有人能帮我确定谷歌地图代码的哪一部分应该只用于获取我需要的东西吗

本文档中的示例不包括地图：

相关代码：

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
  // location types.
  autocomplete = new google.maps.places.Autocomplete(
      /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
      {types: ['geocode']});
}

代码片段：

函数initAutocomplete（）{
//创建自动完成对象，将搜索限制为地理位置
//位置类型。
autocomplete=new google.maps.places.autocomplete(
/**@type{！HTMLInputElement}*/
（document.getElementById（'autocomplete'））{
类型：['geocode']
});
}

您需要提出另一个问题，并展示您的新问题。您的问题指定您不需要地图，现在您的地图有问题。

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
  // location types.
  autocomplete = new google.maps.places.Autocomplete(
      /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
      {types: ['geocode']});
}
