用nodejs实现PHP的print_r函数代码

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）;
