Question

有一个物体

var abb = {"DATA":[{"A":"122","B":"444","C":"fff"},
                    {"A":"1223","B":"6666","C":"s"},
                    {"A":"555","B":"76666","C":"pod"},
                    {"A":"7676","B":"34345","C":""},
                    {"A":"54553","B":"2325555","C":""}]};

这是我的代码

var recursive_f =function(a){
        if(a.length > 0){
            console.log(a[0]);
            recursive_f(a.slice(1));
        }
    }
    recursive_f(abb.DATA);

我的结果是这样的 my result

但是我想要这个 answer

Answer 1

a[0]是一个对象，并且您希望该对象的所有值都在数组中。为此使用Object.values。

var abb = {"DATA":[{"SLIP_NO":"RE2018070006","IO_DATE":"2018-07-11 00:00:00.0","REMARK":"185"},{"SLIP_NO":"RE2012060003","IO_DATE":"2012-06-06 00:00:00.0","REMARK":""},{"SLIP_NO":"RE2012060003","IO_DATE":"2012-06-06 00:00:00.0","REMARK":""},{"SLIP_NO":"RE2018030028","IO_DATE":"2018-03-14 00:00:00.0","REMARK":""},{"SLIP_NO":"RE2018030029","IO_DATE":"2018-03-14 00:00:00.0","REMARK":""}]};

var recursive_f = function(a) {
  if (a.length > 0) {
    console.log(Object.values(a[0]));
    recursive_f(a.slice(1));
  }
}
recursive_f(abb.DATA);

注意：我假设您已经构建了此功能来测试某些东西。因为要遍历数组，应使用Array.forEach或loop的a。
