Question

我有JSON以下，我想通过javascript迭代它。我该怎么做。

var data= {"key1":[{"alfa":"abcd","a":"a1","b":"b1","c":"c1","d":"d1"},
     {"number":"1234","1":"11","22":"2","3":"33","4":"44"}],

      "key2":[{"alfa":"abcd","a":"a1","b":"b1","c":"c1","d":"d1"},
     {"number":"1234","1":"11","2":"22","3":"33","4":"44"}]}

使用的DS：字符串映射，对象列表

Answer 1

Object.keys(data).forEach(key => {
  for(let item of data[key]){
    Object.keys(item).forEach(key => {
      console.log(item[key]) // do stuff here
    })
  }
})

我是这样的

Answer 2

以下是一些如何访问字段的示例：

console.log(data.key1[0].alfa);
console.log(data.key2[0].alfa);
console.log(data.key2[0].a);
