el-form-item 行内多个校验

可以在el-form-item中使用rules属性来进行校验，同时可以使用prop属性来指定需要校验的字段。以下是el-form-item行内多个校验的示例代码：

<template>
 <el-form :model="form" inline>
    <el-form-item label="用户名" prop="username" :rules="[
      { required: true, message: '请输入用户名', trigger: 'blur' },
      { min: 3, max: 5, message: '长度在 3 到 5 个字符', trigger: 'blur' }
    ]">
      <el-input v-model="form.username"></el-input>
    </el-form-item>
    <el-form-item label="密码" prop="password" :rules="[
      { required: true, message: '请输入密码', trigger: 'blur' },
      { min: 6, max: 10, message: '长度在 6 到 10 个字符', trigger: 'blur' }
    ]">
      <el-input type="password" v-model="form.password"></el-input>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submitForm">提交</el-button>
    </el-form-item>
  </el-form>
</template>

<script>
export default {
  data() {
    return {
      form: {
        username: '',
        password: ''
      }
    };
  },
  methods: {
    submitForm() {
      this.$refs.form.validate(valid => {
        if (valid) {
          alert('校验成功');
        } else {
          alert('校验失败');
          return false;
        }
      });
    }
  }
};
</script>
