javascript 解析多層json?

Question

1.我現在從後台接收一個json，大致內容為這樣[{"name":"h","add":"usa","good":"[{"comment":"很棒","mem_na":"a"}]"}]

2.我用了each方法拿取第一層的資料，但第二層，我不知道如何拿取，剛接觸前端，希望有大神幫幫忙
謝謝

Answer 1

if(Array.isArray(value)){    value.forEach((element,index) => {        // 重复第一层的逻辑    })}

Answer 2

不用分层吧，后台传过来的一般就对象或字符串，json字符串的话转换成对象，就能取到内部的数据

抱歉，我不太明白你寫的範例我原本的是用success: function(response){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $.each(response, function() {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; (第一層的資料)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; (這邊開始是第二層)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var goodList=JSON.parse(this.good);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for(var i=0;i<goodList.length;i++){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; });}但我想把它也變成用each方法，我試著嘗試了你的範例，還是不太能明白
