js中用构造函数的方法构造对象
function Person(name = '匿名', age = 0) {
this.name = name
this.age = age
}
Person.prototype = {
constructor: Person,
sayHi() {
console.log(`你好，我是 ${this.name}`)
},
run() {
console.log(`${this.name} 在跑步`)
}
}
const f1 = new Person('fang', 18)
f1.sayHi()
f1.run()
js中用class构造对象
class Person {
constructor(name = '匿名', age = 0) {
this.name = name
this.age = age
}
sayHi() {
console.log(`你好，我是 ${this.name}`)
}
run() {
console.log(`${this.name} 在跑步`)
}
}
