用nodejs實現PHP的print

 這篇文章主要介紹了用nodejs實現PHP的print_r函數代碼,需要的朋友可以參考下

 代碼如下: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);
