如何获取 Google 搜索之类的客户端地理位置？

Question

我想知道，我怎样才能得到像 google 这样的位置？

如图所示： Google 确实宣布了国家/地区的位置 - Province/State - City/Town - District/Block 我读了很多关于 GeoLocation 和 Google Api 的文章，但我不太理解它们。那么有没有人可以帮助我提供示例 html/jquery 代码请注意我不需要 Latitude/Attitude 或其他类似的东西。

这是代码示例

    <!DOCTYPE html>
<html>
  <head>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
    <meta charset="utf-8">

       * element that contains the map. */
      #map {
        height: 100%;
      }
      /* Optional: Makes the sample page fill the window. */
      html, body {
        height: 100%;
