1. 表单验证

在Articles.vue 中

<!-- 编辑界面 -->
		<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @before-close="closeDialog">
			<el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
				<el-form-item label="文章标题" prop="title">
					<el-input size="small" v-model="editForm.title" auto-complete="off" placeholder="请输入文章标题"></el-input>
				</el-form-item>
				<el-form-item label="文章内容" prop="body">
					<el-input size="small" v-model="editForm.body" auto-complete="off" placeholder="请输入文章内容"></el-input>
				</el-form-item>
			</el-form>
			<div slot="footer" class="dialog-footer">
				<el-button size="small" @click="closeDialog">取消</el-button>
				<el-button size="small" type="primary" class="title" @click="submitForm('editForm')">保存</el-button>
			</div>
		</el-dialog>

把对应的属性在script中定义，不然会报错

/* 表单验证 */
				title: '', // 弹出层标题
				editFormVisible: false, // 是否打开弹出层
				editForm: {
					id: 0,
					title: '',
					body: ''
				},
				rules: { // 校验规则
					title: [{
							required: true,
							message: '请输入活动名称',
							trigger: 'blur'
						},
						{
							min: 3,
							max: 10,
							message: '长度在 3 到 10 个字符',
							trigger: 'blur'
						}
					],
					body: [{
						required: true,
						message: '请选择活动区域',
						trigger: 'change'
					}]

				}
			};
		},
		methods: {
			closeDialog() { // 弹出层调用取消的方法
			
			},
			submitForm(formName) { // 提交表单

			},
			handleAdd() { // 新增
			
			},
			handleEdit(index, row) { // 编辑
			
			},
			deleteUser(index, row) { // 删除
			
			},
			clearData() { // 清楚弹出层表单数据
			
			},
			handleClose(done) { // 仅当用户通过点击关闭图标或遮罩关闭 Dialog 时起效。
			
			}
		},

Form组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则，
并将Form-Item的prop属性设置为需校验的字段名即可
注意1：现在的正则是无效的，不满足条件也可以提交成功。需要加入：
(更多可以去elementUi官网查看)

submitForm(formName) {
        this.$refs[formName].validate((valid) => {
          if (valid) {
            alert('submit!');    // 满足正则条件
          } else {
            console.log('error submit!!');  // 不满足
            return false;
          }
        });
      }

2、CRUD（增，删，改）

Articles.vue

<template>
	<div>
		<el-form :inline="true" :model="formInline" class="user-search">
			<el-form-item label="搜索：">
				<el-input size="small" v-model="formInline.title" placeholder="输入文章标题"></el-input>
			</el-form-item>
			<el-form-item>
				<el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
				<el-button size="small" type="primary" icon="el-icon-plus" @click="handleAdd()">添加</el-button>
			</el-form-item>
		</el-form>
		<!--列表-->
		<el-table size="small" :data="listData" border element-loading-text="拼命加载中" style="width: 100%;">

				<template slot-scope="scope">
					<el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
					<el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
				</template>
			</el-table-column>
		</el-table>
		<!--分页条-->
		<el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
		 :current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="100" layout="total, sizes, prev, pager, next, jumper"
		 :total="total">
		</el-pagination>
