    <el-input type="password" v-model="ruleForm2.pass" autocomplete="off"></el-input>
  </el-form-item>
  <el-form-item label="确认密码" prop="checkPass">
    <el-input type="password" v-model="ruleForm2.checkPass" autocomplete="off"></el-input>
  </el-form-item>
  <el-form-item label="年龄" prop="age">
    <el-input v-model.number="ruleForm2.age"></el-input>
  </el-form-item>
