elementPlus 验证输入的正确性

1.首先我们验证登录注册时候的输入密码和手机号码
1先绑定form表单

源码直接贴出来，需要的直接复制就行

    <el-input v-model="registerForm.phonenumber" type="text" size="large" auto-complete="off" placeholder="请输入手机号码">

    </el-input>
  </el-form-item>
  <el-form-item prop="password">
    <el-input v-model="registerForm.password" type="password" size="large" auto-complete="off" placeholder="密码"
      @keyup.enter="handleRegister">
      <template #prefix>
        <svg-icon icon-class="password" class="el-input__icon input-icon" />
      </template>
    </el-input>
  </el-form-item>
  <el-form-item prop="confirmPassword">
    <el-input v-model="registerForm.confirmPassword" type="password" size="large" auto-complete="off"
      placeholder="确认密码" @keyup.enter="handleRegister">
      <template #prefix>
        <svg-icon icon-class="password" class="el-input__icon input-icon" />
      </template>
    </el-input>
  </el-form-item>
