javascript - 使用 Douglas Crockford 的函数继承在 Javascript 中调用基方法

Question

基本上我如何使用下面的这种模式调用基本方法？

var GS = {};
GS.baseClass = function (somedata) {
  var that = {};
  that.data = somedata;

  //Base class method
  that.someMethod = function(somedata) {
    alert(somedata);
  };

  return that;
};

GS.derivedClass = function(somedata) {
 var that = GS.baseClass(somedata);

 //Overwriting base method
 that.someMethod = function(somedata) {
   //How do I call base method from here? 

   //do something else
 };
 return that;
};

谢谢。

var GS = {};GS.baseClass = function (somedata) {  var that = {};  that.data = somedata;  //Base class method  that.someMethod = function(somedata) {    alert(somedata);  };  return that;};GS.derivedClass = function(somedata) { var that = GS.baseClass(somedata); //Overwriting base method var basemethod = that.someMethod; that.someMethod = function(somedata) {   //How do I call base method from here?    basemethod.apply(that, [somedata]);   //do something else }; return that;};
