如何从Javascript中的json数组中提取数组索引0？

Question

我有以下JSON：

[[{"id":37,"address1":"2 town","address2":"apt 111","city":"sanjose","state":"CA","zip":"97878"},{"id":37,"address1":"2 town","address2":"apt 111","city":"sanjose","state":"CA","zip":"97878"}]]

我只需要提取JSON的这一部分：

[{"id":37,"address1":"2 town","address2":"apt 111","city":"sanjose","state":"CA","zip":"97878"},{"id":37,"address1":"2 town","address2":"apt 111","city":"sanjose","state":"CA","zip":"97878"}]

基本上我只需要提取索引[0]的数组。

请允许任何人帮助并提供有关如何在JavaScript中提取上述示例中的json数据的解决方案

你可以尝试这个（假设你的JSON是一个字符串）：

var a = JSON.parse('[[{"id":37,"address1":"2 town","address2":"apt 111","city":"sanjose","state":"CA","zip":"97878"},{"id":37,"address1":"2 town","address2":"apt 111","city":"sanjose","state":"CA","zip":"97878"}]]');

var result = a[0];

希望它可以提供帮助：）
