  }
 },
 created(){
  this.createdCode()
 },
 methods: {
  // 图片验证码
  createdCode(){
   // 先清空验证码输入
   this.code = ""
   this.checkCode = ""
   this.picVerification = ""
   // 验证码长度
   const codeLength = 4
   // 随机数
   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++){
    // 取得随机数的索引(0~35)
    let index = Math.floor(Math.random() * 36)
    // 根据索引取得随机数加到code上
    this.code += random[index]
   }
   // 把code值赋给验证码
   this.checkCode = this.code
  }
