vue年会大转盘抽奖活动代码

Vue移动端抽奖组件，用于大转盘滚动抽奖场景，可配置奖品、图片、转盘样式等。下面web建站小编给大家简单介绍一下具体实现代码！

vue组件安装

import { createApp } from "vue";
// vue
import { Turntable } from "@nutui/nutui-bingo";
// taro
import { Turntable } from "@nutui/nutui-bingo-taro";

const app = createApp();
app.use(Turntable);

vue基础用法

<template>
  <nutbig-turntable
    class="turntable"
    ref="turntable"
    :width="luckWidth"
    :height="luckheight"
    :prize-list="prizeList"
    :turns-number="turnsNumber"
    :turns-time="turnsTime"
    :prize-index="prizeIndex"
    :style-opt="styleOpt"
    :pointer-
    @start-turns="startTurns"
    @end-turns="endTurns"
  >
  </nutbig-turntable>
</template>
<script>
  import { Toast } from "@nutui/nutui";

      // 转盘大小
      const luckWidth = ref("450px");

      // 转盘指针图片样式
      const pointerStyle = {
        width: "80px",
        height: "80px",
