js实现继承机制
function extend(target,parent,params){ parent.apply(target,params); var p = null,o; for(p in parent.prototype){ o = target.constructor.prototype; if(!o[p]){ o[p] = parent.prototype[p]; } o[p]["super"] = parent.prototype; } };
function Person(name){ this.name = name; }; Person.prototype.getName = function(){ alert(this.name); } function Student(name){ extend(this,Person,[name]); };
var stu = new Student("lynn"); stu.getName();
补充:web前端 , JavaScript ,
