vue驗證碼組件使用方法詳解

本文實(shí)例為大家分享了vue驗證碼組件使用的具體實(shí)現代碼，供大家參考，具體內容如下

代碼如下：

<template>

     <div class="join_formitem">
       <label class="enquiry">驗證碼<span>:</span></label>
       <div class="captcha">
         <input type="text" placeholder="請輸入驗證碼" class="yanzhengma_input" v-model="picLyanzhengma" />
         <input type="button" @click="createdCode" class="verification" v-model="checkCode" />
       </div>
    </div>
</template>

<script>
export default {
  data(){
    return{
      code:'',
      checkCode:'',                   
      picLyanzhengma:''         //..驗證碼圖片
    }
  },
  created(){
    this.createdCode()
  },
  methods: {
    // 圖片驗證碼
    createdCode(){
      // 先清空驗證碼輸入
      this.code = ""
      this.checkCode = ""
      this.picLyanzhengma = ""
      // 驗證碼長(cháng)度
      const codeLength = 4
      // 隨機數
      const random = new Array(0,1,2,3,4,5,6,7,8,9,'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z')
      for(let i = 0;i < codeLength;i++){
        // 取得隨機數的索引(0~35)
        let index = Math.floor(Math.random() * 36)
        // 根據索引取得隨機數加到code上
        this.code += random[index]
      }
      // 把code值賦給驗證碼
      this.checkCode = this.code
    }
  }
}
</script>

<style>
.yanzhengma_input{
  font-family: 'Exo 2',sans-serif;
