从JavaScript函数中提取国家、州、城市和地区的信息,这些信息在Spring mvc中直接给出了完整的地址

Extract information from JavaScript function in terms of country, state, city and locality which directly gives full address in Spring mvc

本文关键字:信息 Spring mvc 地址 国家 提取 函数 JavaScript 城市 地区      更新时间:2023-09-26

我必须添加国家,州,城市和剩余的地址,如果它包含。但我不熟练使用谷歌API和JavaScript。我使用的是现成的JavaScript函数,它在使用自动完成后在文本框上给出完整的地址。

我不知道如何从完整的地址中获取或提取国家、州、城市。

我给出了我的代码:

感谢您的回复。从这个关于搜索位置的输出中,我想提取单个县、州、城市和位置,并在Spring MVC类pojo中使用。

下面是您应该感兴趣的代码部分(来自您提供的代码)。

var 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(' ');
}
从本质上讲,这部分所做的是初始化地址变量(初始为空)。然后,如果place对象(假定是从Google返回的)不为空并且包含组件,则用来自place的所有独立组件填充地址。上面的代码暗示了Google返回的place对象具体地为您提供了三(3)个组件:位于索引位置0、1和2的组件。

您必须弄清楚这些组件是否单独提供了您需要的独立信息。要检查这一点,请尝试使用以下代码进行更新(注意我添加的FOR循环):

var 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(' ');
  for (var i = 0; i < place.address_components.length; i++)
  {
      console.log('Component at index ' + i 
        + ' is: ' + place.address_components[i].short_name;
  }
}

运行更新后的代码并检查您的控制台(可与Chrome一起使用)-它会让您知道哪些组件由Google返回,以及它们的索引号。利用这些知识来实现你的目标。
