# 前言

之前,看到一个比较有意思的小程序,就是静神木鱼,可以实现在线敲木鱼,自动敲木鱼,手盘佛珠,静心颂钵的

整个小程序功能比较小巧,大道之简,风靡过一阵的,而且赚得盆满钵满的,下面就实现一下这个小程序中敲木鱼的例子的

# 小程序示例

# 具体示例

静神木鱼

# 具体代码

示例代码如下所示

<template>
  <div class="leijia-wrap">
        <div class="leijia-content">
             <h2>静神木鱼</h2>
             <div class="text">{{count}}<span class="animatetip" v-show="isTip">功德+1</span></div>
             <div class="btn">
                 <el-button type="primary" size="mini" @click="handleClick" ref="btnClick">敲击</el-button>
                 <el-button type="primary" size="mini" @click="handleVoince" ref="btnJinYin">{{isVoince == true?'非静音':'静音'}}</el-button>
                 <el-button type="danger" size="mini" @click="handleAuto">{{onOff == true?'自动':'非自动'}}</el-button>
                 <el-button type="info" size="mini" @click="handleClear">清除</el-button>
             </div>
        </div>
