登录页添加验证码

  1. 引入验证码页面组件:ValidCode.vue
<template>
  <div class="ValidCodeContent" style="">
    <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>
    <div class="kbq" @click="refreshCode">看不清</div>
  </div>
</template>

<script>
export default {
  name: 'validCode',
  props: {
    width: {
      type: String,
      default: '100px',
    },
    height: {
      type: String,
      default: '40px',
    },
    length: {
      type: Number,
      default: 4,
    },
  },
  data() {
    return {
      codeList: [],
    }
  },
  mounted() {
    this.createdCode()
  },
  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)),
          color: `rgb(${rgb})`,
          fontSize: `1${[Math.floor(Math.random() * 1 + 9)]}px`,
          padding: `${[Math.floor(Math.random() * 2 + 4)]}px`,
          transform: `rotate(${
            Math.floor(Math.random() * 90) - Math.floor(Math.random() * 90)
          }deg)`,
        })
      }
      // 指向
      this.codeList = codeList
      // 将当前数据派发出去
      this.$emit('update:value', codeList.map((item) => item.code).join(''))
    },
    getStyle(data) {
      return `color: ${data.color}; font-size: ${data.fontSize}; padding: ${data.padding}; transform: ${data.transform};`
    },
  },
}
</script>
