  //获取验证码
    getCode () {

      let codeString = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
      let codeArray = codeString.split('')
      let num = codeArray.length
      let newCodeArray = []
      for (let i = 0; i < 5; i++) {
        let index = Math.floor(Math.random() * num)
        newCodeArray.push(codeArray[index])
      }
      this.viewCode = newCodeArray.join('')
    },
  },
  mounted () {
    this.getCode()
    if (localStorage.getItem('rememberInfo')) {
      // 有上次登录信息 显示上次登录
      let rememberData = JSON.parse(localStorage.getItem('rememberInfo'))
      const { account, password } = rememberData
      this.loginForm.account = account
      this.loginForm.password = password
    }
  }

样式代码省略。。。
