删除JSON根目录 [英] Remove JSON root

问题描述

我在JavaScript变量上有以下字符串：

I have the following string on a JavaScript variable:

my_Variable = "{"Domini":[{"cod_domini":"1","nom_domini":"Sant Esteve de Palautordera"},{"cod_domini":"2","nom_domini":"Parc Natural del Montseny"},{"cod_domini":"5","nom_domini":"Sant Pere de Vilamajor"},{"cod_domini":"6","nom_domini":"Santa Maria i Mosqueroles"}]}"

我需要删除字符串 Domini 顶部的根，所以结果字符串如下所示：

I need to remove the root at the top of string Domini so the resultant string looks like this:

my_Variable = [{"cod_domini":"1","nom_domini":"Sant Esteve de Palautordera"},{"cod_domini":"2","nom_domini":"Parc Natural del Montseny"},{"cod_domini":"5","nom_domini":"Sant Pere de Vilamajor"},{"cod_domini":"6","nom_domini":"Santa Maria i Mosqueroles"}]

我试图使用 JSON.parse（）函数，它可以工作，但后来我不知道如何检索数据并处理它以生成一个没有r的新JSON oot。

I've tried to parse JSON to an object using JSON.parse() function and it works, but then I don't know how to retrieve the data and handle it to generate a new JSON without root.

我应该使用某种循环吗？

Should I be using some kind of loop?

推荐答案

这很简单：

my_Variable = my_Variable.Domini;

在JSON解析之后。

所以代码将如下：

my_Variable = "{"Domini":[{"cod_domini":"1","nom_domini":"Sant Esteve de Palautordera"},{"cod_domini":"2","nom_domini":"Parc Natural del Montseny"},{"cod_domini":"5","nom_domini":"Sant Pere de Vilamajor"},{"cod_domini":"6","nom_domini":"Santa Maria i Mosqueroles"}]}";
my_Variable = JSON.parse( my_Variable );
my_Variable = my_Variable.Domini;
console.log( my_Variable ); // [{"cod_domini":"1","nom_domini": ...
