Jquery通过Json循环使用对象数组并获取键名

I am able to read a json array from php, i want to display the key name of the items aswell. This might not make sense now but please check below code.

My json data

我能够从php读取一个json数组,我想显示项目的关键名称。这可能现在没有意义,但请检查下面的代码。我的json数据

{ "A":{"Africa":"201455632", "Asia":"5145000"}, 
  "B":{"Brasil":"68455222"},
  "C":{"China":"14546787"}
 }

My js code i am able to dislplay the key-val pair

我的js代码我可以打开key-val对

 $.each(data, function() {
     console.log('---')
     $.each(this, function(k, v) {
      console.log(k, v)
     });
 });

Its displays like this

它的显示是这样的

  ---
  Africa 201455632
  Asia 5145000 
  ---
  Brasil 68455222 
  ---
  China 14546787

My Problem is, i want to display it like this, with their key name aswell, what can i replace console.log('---') with

我的问题是,我希望用它们的关键名称显示它,还有什么可以替换console.log('---')

A
  Africa 201455632
  Asia 5145000
B
  Brasil 68455222
C
  China 14546787

#1

Use the parameters to the callback function (just like you did with the inner loop).

将参数用于回调函数(就像使用内循环一样)。

$.each(data, function(key, value) {
    console.log(key);
    $.each(value, function(k, v) {
        console.log('  ' + k, v);
    });
});

jsfiddle

#2

$.each(data, function(key, value) {
     console.log(key)
     $.each(value, function(k, v) {
      console.log(k, v)
     });
 });

Hope its help.
