第一步,创建wxs并导出 function formatPrice(price) { return "¥" + price } function calcPrice(books) { return "¥" + books.reduce(function(preValue, item) { return preValue + item.price }, 0) } // 对count进行格式化 function formatCount(count) { count = Number(count) if (count >= 100000000) { return (count / 100000000).toFixed(1) + "亿" } else if (count >= 10000) { return (count / 10000).toFixed(1) + "万" } else { return count } } // 必须导出后, 才能被其他地方调用: 必须使用CommonJS导出 module.exports = { formatPrice: formatPrice, calcPrice: calcPrice, formatCount: formatCount, }
2.使用 <!-- 独立的文件, 通过src引入 --> <wxs module="format" src="/utils/format.wxs"></wxs> <view class="books"> <block wx:for="{{books}}" wx:key="id"> <view>name:{{item.name}}-price:{{format.formatPrice(item.price)}}</view> </block> </view> <view class="total">总价格: {{format.calcPrice(books)}}</view> <view>------------题目练习------------</view> <view class="count">播放量: {{format.formatCount(playCount)}}</view>
3.数据 // pages/05_learn_wxs/index.js Page({ data: { books: [ { id: 111, name: "代码大全", price: 98, coverURL: "" }, { id: 112, name: "你不知道JS", price: 87, coverURL: "" }, { id: 113, name: "JS高级设计", price: 76, coverURL: "" }, ], playCount: 2232, duration: 255, currentTime: 65 }, })
