弹出对话框
<!--点击事件add（）弹出增加文章的对话框 -->
<el-button size="small" type="primary" icon="el-icon-plus" @click="add()">增加</el-button>
<!-- 编辑界面 -->
<el-dialog title="title" :visible.sync="dialogVisible" width="30%">

- 表单验证
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1：有多个表单，怎么在提交进行区分？
<el-form :model="editFrom" :rules="rules" ref="editFrom.title">
<el-form-item label="文章标题" prop="tilte">
<el-input v-model="editFrom.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 v-model="editFrom.body" auto-complete="off" placeholder="请输入文章内容"></el-input>
</el-form-item>
</el-from>
<script>
export default {
data() {
return {
dialogVisible: false,
title: '',
editFrom: {
title: '',
body: '',
id: 0
},
rules: {
title: [{
required: true,
message: '请输入文章标题',
trigger: 'blur'
},
{
min: 3,
max: 20,
message: '长度在 3 到 20 个字符',
trigger: 'blur'
}
],
body: [{
required: true,
message: '请输入文章内容',
trigger: 'blur'
},
{
min: 3,
max: 500,
message: '长度在 3 到 500 个字符',
trigger: 'blur'
}
]
}
};
</script>
我们在rules这里写了对表单的验证规则，但是我们如何在methods里进行指定的表单进行认证，
所以我们一开始就在el-form里写了 ref="ruleForm"，我们在methods里就可以用
<template>
<div>
<el-form :inline="true" :model="formInline" class="user-search">
<el-form-item label="搜索:">
<el-input size="small" v-model="formInline.deptName" 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="add()">增加</el-button>
</el-form-item>
</el-form>
<el-table :data="Data" border style="width: 100%">
<el-table-column prop="id" label="id" width="180">
</el-table-column>
<el-table-column prop="tile" label="文章标题" width="180">
</el-table-column>
<el-table-column prop="body" label="文章内容">
</el-table-column>
</el-table-column>
</el-table>
<!-- 分页条 -->
<el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
