1.表单验证

代码：

<!--增加/ 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>

data() {
			return {
				listData: [],
				formInline: {
					page: 1,
					rows: 10,
					title: ''
				},
				total: 0,
				title: '',
				editFormVisible: false,
				editForm: {
					title: '',
					body: '',
					id: 0
				},
				rules: {
					title: [{
							required: true,
							message: '请输入活动名称',
							trigger: 'blur'
						},
						{
							min: 3,
							max: 5,
							message: '长度在 3 到 5 个字符',
							trigger: 'blur'
						}
					],
					body: [{
						required: true,
						message: '请输入活动名称',
						trigger: 'blur'
					}]
				}
			};
		},

效果图：

 鼠标离开文本框时就会有提示且要按要求输入；

2.增删改功能的实现

1、保障编辑窗体能够正常弹出

2、表单校验通过后，调用后台数据接口完成新增功能

增删改的代码：

<template>
  <div>
    <!--  搜索筛选-->
    <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="handleEdit()">添加</el-button>
      </el-form-item>
    </el-form>
 
    <!--列表-->
    <el-table size="small" :data="listData" highlight-current-row style="width: 100%;">
      <el-table-column align="center" type="selection" min-width="60">
      </el-table-column>

          <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"

        <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">
