Object.prototype.method 不起作用

Question

我已经为 Object 创建了这个原型方法，但它停止了我的所有代码，当我测试它时，它适用于某些对象列表，但以下代码不起作用。 谢谢你帮助我。

Object.prototype.toMapIt = function(){
  var arrayFinal = [];
  for(var key in this){
    if(key != "toMapIt"){
      var array = [];
      array.push(key);
      array.push(this[key]);
      arrayFinal.push(array);
    }
  }
  return new Map(arrayFinal);
}

//Using the method
var object = {key1 : value1, key2 : value2};

var map = object.toMapIt();

Answer 1

所以我没有这个问题：

 var toMap = function(object){ var finalArray = []; for(var key in object){ var array = []; array.push(key); array.push(object[key]); finalArray.push(array); } return new Map(finalArray); } $(function(){ var test = {ko : "jiioji", opop : "ijoijoij"}; console.log(test); console.log(toMap(test)); });
