学习vue时发现代码里不让写注释，这对新手太不友好了。
index.vue 源代码 三部分：template，script，style
一 、template 模板部分
1 <template> 2 <div class="index" v-cloak> 3 <div class="header acea-row row-center-wrapper"> 4 <div class="logo"><img :src="logoUrl" /></div> 5 <router-link :to="'/search'" class="search acea-row row-middle"> 6 <span class="iconfont icon-xiazai5"></span>搜索商品 7 </router-link> 8 </div> 9 <div class="slider-banner banner"> 10 <swiper :options="swiperOption" v-if="banner.length > 0"> 11 <swiper-slide v-for="(item, index) in banner" :key="index"> 12 <router-link 13 :to="item.wap_url ?

二、script JavaScript代码部分
1 <script> 2 import { swiper, swiperSlide } from "vue-awesome-swiper"; // 3 import "@assets/css/swiper.min.css"; //@在vue.config.js里定义的路径 4 import GoodList from "@components/GoodList"; 5 import PromotionGood from "@components/PromotionGood"; 6 import CouponWindow from "@components/CouponWindow"; 7 import { getHomeData, getShare } from "@api/public"; 8 import cookie from "@utils/store/cookie"; 9 import { openShareAll } from "@libs/wechat"; 10 import { isWeixin } from "@utils/index"; 11 12 const HAS_COUPON_WINDOW = "has_coupon_window"; 13 14 export default { 15 name: "Index", //组件名称，递归调用，和调试用。参见：https://blog.csdn.net/weixin_39015132/article/details/83573896 16 components: { 17 swiper, 18 swiperSlide, 19 GoodList, 20 PromotionGood, 21 CouponWindow 22 }, 23 props: {}, 24 data: function() { //data https://www.cnblogs.com/bester-ace/articles/9895310.html https://www.cnblogs.com/zhengyb/p/10456579.html 25 return { 26 showCoupon: false, 27 logoUrl: "", 28 banner: [], 29 menus: [], 30 roll: [], 31 activity: [], 32 activityOne: {}, 33 info: { 34 fastList: [], 35 bastBanner: [], 36 firstList: [], 37 bastList: [] 38 }, 39 likeInfo: [], 40 lovely: [], 41 benefit: [], 42 couponList: [], 43 swiperOption: { 44 pagination: { 45 el: ".paginationBanner", 46 clickable: true 47 }, 48 autoplay: { 49 disableOnInteraction: false, 50 delay: 2000 51 }, 52 loop: true, 53 speed: 1000, 54 observer: true, 55 observeParents: true 56 }, 57 swiperRoll: { 58 direction: "vertical", 59 autoplay: { 60 disableOnInteraction: false, 61 delay: 2000 62 }, 63 loop: true, 64 speed: 1000, 65 observer: true, 66 observeParents: true 67 }, 68 swiperScroll: { 69 freeMode: true, 70 freeModeMomentum: false, 71 slidesPerView: "auto", 72 observer: true, 73 observeParents: true 74 }, 75 swiperBoutique: { 76 pagination: { 77 el: ".paginationBoutique", 78 clickable: true 79 }, 80 autoplay: { 81 disableOnInteraction: false, 82 delay: 2000 83 }, 84 loop: true, 85 speed: 1000, 86 observer: true, 87 observeParents: true 88 }, 89 swiperProducts: { 90 freeMode: true, 91 freeModeMomentum: false, 92 slidesPerView: "auto", 93 observer: true, 94 observeParents: true 95 } 96 }; 97 }, 98 mounted: function() { //mounted在模板渲染成html后调用，通常是初始化页面完成后，再对html的dom节点进行一些需要的操作 参见：https://blog.csdn.net/xinghuowuzhao/article/details/79983472 99 let that = this; // this？ 100 getHomeData().then(res => { //.then 操作完成之后执行，参见 https://www.jianshu.com/p/0c91f7de1675 getHomeData 是组件 public里定义的方法，这里应该是获取数据完成后执行 101 that.logoUrl = res.data.logoUrl; 102 that.$set(that, "banner", res.data.banner); //vue 通过$set方法 将响应属性添加到嵌套的对象上 参见 https://www.jianshu.com/p/71b1807b1815 https://www.jianshu.com/p/70b2e2e0aa11 103 that.$set(that, "menus", res.data.menus); 104 that.$set(that, "roll", res.data.roll); 105 that.$set(that, "activity", res.data.activity); 106 if (res.data.activity.length) { 107 var activityOne = res.data.activity.shift(); 108 that.$set(that, "activityOne", activityOne); 109 } 110 that.$set(that, "info", res.data.info); 111 that.$set(that, "likeInfo", res.data.likeInfo); 112 that.$set( 113 that, 114 "lovely", 115 res.data.lovely.length ? res.data.lovely[0] : {} 116 ); 117 that.$set(that, "benefit", res.data.benefit); 118 that.$set(that, "couponList", res.data.couponList); 119 that.setOpenShare(); 120 this.showCoupon = 121 !cookie.has(HAS_COUPON_WINDOW) && 122 res.data.couponList.some(coupon => coupon.is_use); //some 数组中部分元素满足条件 funcion（coupon）{return coupon.is_use;} 123 }); 124 }, 125 methods: { //methods 被命名为方法，是调用对象上下文中的函数，还可以操作对象中包含的数据。 参见 https://blog.csdn.net/ll594317566/article/details/90602326 126 couponClose() { 127 cookie.set(HAS_COUPON_WINDOW, 1); 128 }, 129 setOpenShare: function() { 130 if (isWeixin()) { 131 getShare().then(res => { 132 var data = res.data.data; 133 var configAppMessage = { 134 desc: data.synopsis, 135 title: data.title, 136 link: location.href, 137 imgUrl: data.img 138 }; 139 openShareAll(configAppMessage); 140 }); 141 } 142 } 143 } 144 }; 145 </script>
三、style css 样式部分
<style scoped>
.index {
background-color: #fff;
}
</style>
