访问嵌套元素在JSON阵列

Question

我将如何访问值标签以下JSON数组中

[ { _id: 596e0053e405e523bca7d289, 
'[{"type":"button","label":"Button","subtype":"button","className":"btn- 
default btn","name":"button-1500381266064","style":"de 
fault"}]': '' }, 
{ _id: 596e0053e405e523bca7d28a } ] 

Answer 1

据我了解您的JSON是一个属性的名字，鉴于GUID作为字符串此提供应工作：

var t=[ { _id: '596e0053e405e523bca7d289', 
 
'[{"type":"button","label":"Button","subtype":"button","className":"btn-default btn","name":"button-1500381266064","style":"default"}]': '' },{ _id: '596e0053e405e523bca7d28a' } ] 
 

 
function propName(prop, value){ 
 
    for(var i in prop) { 
 
     if (prop[i] == value){ 
 
      return i; 
 
     } 
 
    } 
 
    return false; 
 
} 
 

 

 
console.log(JSON.parse(propName(t[0], ""))[0].label)
