Home page carousel imageThere are several forms of carousel, For example, the common horizontal poster image display, as well as the horizontal and vertical product list display, and the headline information box rotation
siwper component very well realizes the horizontal poster image display, such as
<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}"> <block wx:for="{{imgUrls}}" wx:key="index"> <swiper-item> <image src="{{item}}" class="slide-image" /> </swiper-item> </block> </swiper>However, there are some differences that need to be paid attention to when sliding horizontally. Details
First add scroll-x-="true" to the swiper component
Then set display: inline-block; white-space: nowrap;
## to the parent container of the carousel's child elements #The headline information box conversion adopts up and down rotation, and is completed using scroll-view nested swiper
<scroll-view scroll-y-="true" > <swiper autoplay="{{autoplay}}" interval="{{interval1}}" duration="{{duration}}" vertical="true"> <block wx:for="{{something}}" wx:key="index"> //内容 </block> </swiper> </scroll-view>
2. Classified product management
wx.request({ url: 'http://www.easy-mock.com/mock/5a1ffb42583969285ab22bb7/orderOnline/orderOnline', complete: res => { this.globalData.classifyList = res.data; }, })
. And some personal information, such as date of birth and account information, can be saved through wx. setStorage and wx.getStorage are put into local storage
3. Shopping cart operation
For example, reduce the number of items in the shopping cart.
reduceItems: function (e) { let carts = app.globalData.carts; //获取购物车的信息 let classifyList = app.globalData.classifyList; //获取商品的信息 for (let key of carts) { //遍历购物车数组 if (key.id === e.target.dataset.id) { //通过WXML中 view里面的bind-id传过来的参数进行查找 key.cartSelected = true; if (key.num === 1) { //如果数量为1还要减 key.num--; key.cartSelected = false; //购物车不选中 key.selected = false; //商品中不选中 app.globalData.carts = carts.filter((item) => { //进行购物车中商品剔除 return item.id != e.target.dataset.id; }) } else { key.num--; } } } let num = 0; //实时更新购物车小计界面显示 let totalPrice = 0; for (let key of carts) { if (key.cartSelected) { num += key.num; totalPrice += key.num * key.price; } } this.setData({ //通过setData进行当前页面Data数据管理 cart: app.globalData.carts, cartTotal: num, cartTotalPrice: totalPrice, }) },
