复制代码 代码如下:

function ergodic(obj,indentation){
  var indent = \"  \" + indentation;
  if(obj.constructor == Array || obj.constructor == Object){

    for(var p in obj){
      if(obj[p].constructor == Array|| obj[p].constructor == Object){
        console.log(indent + \"[\"+p+\"] => \"+typeof(obj)+\"\");
        console.log(indent + \"{\");
        ergodic(obj[p], indent);
        console.log(indent + \"}\");
      } else if (obj[p].constructor == String) {
        console.log(indent + \"[\"+p+\"] => \'\"+obj[p]+\"\'\");
      } else {
        console.log(indent + \"[\"+p+\"] => \"+obj[p]+\"\");
      }
    }
  }
}

function print_r(obj) {
  console.log(\"{\")
  ergodic(obj, \"\");
  console.log(\"}\")
}

var stu = {\'name\':\'Alan\',\'grade\':{\'Chinese\':120,\'math\':130,\'competition\':{\'NOI\':\'First prize\'}}};

print_r(stu);
