微信小程序九宫格抽奖活动制作

首先安装npm包

npm install @lucky-canvas/mini@latest

然后构建 npm

1. 微信开发者工具 -> 找到左上角点击 -> 工具
2. 点击 -> 构建 npm
3. 弹窗提示 构建成功 即可

引入自定义组件

{
  ...
  "usingComponents": {
    "lucky-wheel": "/miniprogram_npm/@lucky-canvas/mini/lucky-wheel/index",
    "lucky-grid": "/miniprogram_npm/@lucky-canvas/mini/lucky-grid/index"
    "slot-machine": "/miniprogram_npm/@lucky-canvas/mini/slot-machine/index"
  }
  ...
}

然后就可以根据官网实例进行制作啦

以下是我的一个demo

wxml：

js：

data: {
        blocks: [{
            padding: '20px',
            imgs: [{
                src: '/image/k_bg.gif',
                width: '100%',
                height: '100%'
            }]
        }],
        prizes: [
            {
                x: 0, y: 0, range: 1, fonts: [{ text: '一等奖', top: '60px', fontSize: '14px' }], imgs: [{

   start() {
        // 获取抽奖组件实例
        const child = this.selectComponent('#myLucky')
        // 调用play方法开始旋转
        child.lucky.play()
        // 用定时器模拟请求接口
        setTimeout(() => {
            // 3s 后得到中奖索引 (假设抽到第0个奖品)
            // 调用stop方法然后缓慢停止
            child.lucky.stop()
        }, 6000)
    },
    end(event) {
        // 中奖奖品详情
        console.log(event.detail)
    },

实际效果图如下：
