需要 htm -c 手動 idt 註意 log fun clas
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> </head> <body> <script> function Student(name, age, sex) { this.name = name; this.age = age; this.sex = sex; } //簡單的原型寫法 Student.prototype= { //手動修改構造器的指向 constructor: Student, height: 188, width: 55, study: function () { return this.name + "在學習"; }, eat: function () { return this.name + "在吃飯"; } }; var stu = new Student("Andy", 18, "男"); console.log(stu.study()); console.log(stu.eat()); console.dir(stu); console.dir(Student);//註意需要手動修改構造器的指向 </script> </body> </html>
