前言

@lucky-canvas/vue

一、查看nodejs版本

node -v

二、创建项目

1、安装插建

npm install @lucky-canvas/vue --save

2、目录结构

3、引用main.js

import Vue from 'vue';
import App from './App.vue';
import router from './router';
import VueLuckyCanvas from '@lucky-canvas/vue';
Vue.use(VueLuckyCanvas);
Vue.config.productionTip = false
new Vue({render: h => h(App),router
}).$mount('#app')

4、配置路由src/router/index.js

import Vue from 'vue';
import Router from 'vue-router';
import LuckyWheel  from '@/components/LuckyWheel.vue';
import LuckyGrid  from '@/components/LuckyGrid.vue';
import SlotMachine   from '@/components/SlotMachine .vue';
Vue.use(Router);
const routes = [{ path: '/', component: LuckyWheel  },{ path: '/lucky-wheel', component: LuckyWheel  },{ path: '/lucky-grid', component: LuckyGrid  },{ path: '/slot-machine', component: SlotMachine },]
export default new Router({ routes })

三、大转盘

1、src/components/LuckyWheel.vue

<template><div class="lucky_wheel"><h1>LuckyWheel页面</h1><template><LuckyWheelref="myLucky"width="400px"height="400px":prizes="prizes":blocks="blocks":buttons="buttons"@start="startCallback"@end="endCallback"/>
