7. Prototyping

function Swiper(imgArr, container){ this.imgArr = imgArr this.container = container this.createImg = function() { console.log('createimg') } this.changeImg = function() { console.log('changeImg') } } function SlideLooper(imgArr, container) { Swiper.call(this, imgArr, container) this.changeImg = function() { console.log('SlideLooper') } } function Swiper2(imgArr, container) { this.imgArr = imgArr this.container = container } Swiper2.prototype = { createImg: function () { console.log('Swiper2,createImg') }, changeImg: function () { console.log('swpier2,changeImg') } } function SliderLooper2(imgArr, container) { Swiper2.call(this, imgArr, container) } SliderLooper2.prototype = new Swiper2() // SliderLooper2.prototype.changeImg = function() { // Console. log('SliderLooper2,changeImg') //} let eg1 = new SliderLooper2([1,2,3],['one','two']) eg1.changeimg () // inheritance function function ExtendPrototype() { let args = arguments function F() { } for (let i = 0; i < args.length; i++) { for(var j in args[i]) { F.prototype[j] = args[i][j] } } return new F() } let eg2 = new ExtendPrototype ({name:'guohua', age:'24'},{code: function(){ console.log('codecode') }})Copy the code
