基于vue的验证码组件的示例代码

<template>
 <div class="ValidCode disabled-select" :style="`width:${width}; height:${height}`" @click="refreshCode">
  <span v-for="(item, index) in codeList" :key="index" :style="getStyle(item)">{{item.code}}</span>
 </div>
</template>

 methods: {
  refreshCode () {
   this.createdCode()
  },
  createdCode () {
   let len = this.length,
    codeList = [],
    chars = 'ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz0123456789',
    charsLen = chars.length
   // 生成
   for (let i = 0; i < len; i++) {
    let rgb = [Math.round(Math.random()  220), Math.round(Math.random()  240), Math.round(Math.random()  200)]
    codeList.push({
     code: chars.charAt(Math.floor(Math.random()  charsLen)), // 随机码
     color: `rgb(${rgb})`, // 随机颜色
     fontSize: `1${[Math.floor(Math.random()  10)]}px`, // 随机字号
     padding: `${[Math.floor(Math.random()  10)]}px`, // 随机内边距
     transform: `rotate(${Math.floor(Math.random()  90) - Math.floor(Math.random()  90)}deg)` // 随机旋转角度
    })
   }
   // 指向
   this.codeList = codeList
   // 将当前数据派发出去
   this.$emit('update:value', codeList.map(item => item.code).join(''))
  },
  // 动态绑定样式
  getStyle (data) {
   return `color: ${data.color}; font-size: ${data.fontSize}; padding: ${data.padding}; transform: ${data.transform}`
