實例1：

function SuperType(name){
        this.name = name;
        this.colors = [‘red‘,‘green‘,‘blue‘];
    }

    SuperType.prototype.sayName = function(){
        console.log(this.name);
    }
    
    function SubType(name,age){
        SuperType.call(this,name);
        this.age = age;    
    }
    
    
 
function inheritPrototype(SubType,SuperType){
        SuperType.prototype.constructor = SubType;//把上邊的兩個函數合並
        SubType.prototype = SuperType.prototype;
    }
    /**
        公用的構造函數
        function SubType(name,age){
            this.name = name;
            this.colors = [‘red‘,‘green‘,‘blue‘];
            this.age = age;    
        }

    
 
*/
    inheritPrototype(SubType,SuperType);

    SubType.prototype.sayAge = function(){
        console.log(this.age);
    }

    var p1 = new SubType(‘zhangsan‘,89);
    p1.sayName();
    p1.sayAge();
    console.log(p1.colors);
    console.log(p1);

這個是利用call()和SuperType.prototype.constructor = SubType;//把上邊的兩個函數合並函數公用一個構造函數
