## 新建表单
1. 加入弹窗组件，并填上表单配置，完整代码如下
~~~
<template>
<basic-container>
<el-row>
<el-col :span="24">
<div class="tool-box">
<el-button type="primary" icon="el-icon-circle-plus-outline" size="small" @click="handleAdd">新增</el-button>
<el-button type="danger" icon="el-icon-delete" size="small" @click="handleMultiDelete">批量删除</el-button>
</div>
</el-col>
</el-row>
<el-row>
<el-table
:data="data"
@selection-change="selectChange"
style="width: 100%">
<el-table-column
prop="id"
type="selection"
width="55">
</el-table-column>
<el-table-column
prop="title"
label="标题"
width="180">
</el-table-column>
<el-table-column
prop="content"
label="内容">
</el-table-column>
<el-table-column
prop="time"
label="日期"
width="180">
</el-table-column>
<el-table-column label="操作" fixed="right" width="250">
<template slot-scope="scope">
<el-button

@click="handleView(scope.$index, scope.row)">查看
</el-button>
<el-button

@click="handleEdit(scope.$index, scope.row)">编辑
</el-button>
<el-button

</el-button>
</template>
</el-table-column>
</el-table>
</el-row>
<el-row>
<el-pagination
background
:page-sizes="[10, 20, 30, 50]"
:page-size="10"
layout="total, sizes, prev, pager, next, jumper"
@size-change="sizeChange"

:total="page.total">
</el-pagination>
</el-row>
<el-dialog :title="dialogTitle" width="600px" :visible.sync="formVisible" @close="resetForm('blogForm')">

</el-form-item>
<el-form-item label="内容" label-width="55px">
<el-input v-model="blog.content" autocomplete="off" type="textarea" :rows="5"></el-input>
</el-form-item>
</el-form>
<div slot="footer" class="dialog-footer">
<el-button @click="formVisible = false">取 消</el-button>
<el-button type="primary" @click="submitBlog('blogForm')">确 定</el-button>
</div>
</el-dialog>
</basic-container>
</template>
<script>
import {getList, submit} from '@/api/demo/blog'
export default {
data() {
return {
// 是否显示
formVisible: false,
// dialog标题
dialogTitle: '',
// 列表数据
data: [],
// 选中的数据
multiSelection: [],
// 分页数据
page: {
pageSize: 10,
currentPage: 1,
total: 0
},
// 校验规则
rules: {
title: [
{required: true, message: '请输入标题', trigger: 'blur'},
]
},
// 表单映射模型

}
},
created() {
this.onLoad();
},
methods: {
onLoad() {
getList().then(res => {
this.data = res.data.data.records;
this.page.total = res.data.data.total;
})
},
selectChange(val) {
this.multiSelection = val
},
currentChange(currentPage) {
this.page.currentPage = currentPage;
},
sizeChange(pageSize) {
this.page.pageSize = pageSize;
},
resetForm(formName) {
this.$refs[formName].clearValidate()
},
handleAdd() {
this.dialogTitle = '新增博客';
this.formVisible = true;
console.log("add")
},
handleView(index, row) {
console.log("view");
console.log(index);
console.log(row);

// 表单验证
this.$refs[formName].validate((valid) => {

console.log(this.blog);
submit(this.blog).then(res => {
if (res.data.success) {
this.formVisible = false;
this.$message({
type: 'success',
message: '操作成功！'
})
} else {
this.$message({
type: 'error',
message: res.data.msg
})
}
})
}
})
},
}
}
</script>
<style lang="scss" scoped>
.el-pagination {
margin-top: 20px;
}
</style>

2. 我们来详细分析每一个代码块的作用及目的
* 如下代码定义了一个dialog组件，并且包裹了表单组件
~~~
<el-dialog :title="dialogTitle" width="600px" :visible.sync="formVisible" @close="resetForm('blogForm')">
<el-form :model="blog" :rules="rules" ref="blogForm">
<el-form-item label="标题" prop="title" label-width="55px">
<el-input v-model="blog.title" autocomplete="off"></el-input>
</el-form-item>
<el-form-item label="时间" label-width="55px">
<el-date-picker
v-model="blog.time"
style="width: 100%;"
type="date"
value-format="yyyy-MM-dd"
placeholder="选择日期"
autocomplete="off">
</el-date-picker>
</el-form-item>
<el-form-item label="内容" label-width="55px">
<el-input v-model="blog.content" autocomplete="off" type="textarea" :rows="5"></el-input>
</el-form-item>
</el-form>
<div slot="footer" class="dialog-footer">
<el-button @click="formVisible = false">取 消</el-button>
<el-button type="primary" @click="submitBlog('blogForm')">确 定</el-button>
</div>
</el-dialog>
~~~
* 如下的属性分别代表了：绑定标题、设定宽度、设定弹窗可视、设定关闭事件
~~~
<el-dialog :title="dialogTitle" width="600px" :visible.sync="formVisible" @close="resetForm('blogForm')">
~~~
* 如下的属性分别代表了：绑定form的数据、设定校验规则、定义表单别名
~~~
<el-form :model="blog" :rules="rules" ref="blogForm">
~~~
* 如下的属性设定了表单内的三个字段：标题、事件、内容
~~~
<el-form-item label="标题" prop="title" label-width="55px">
<el-input v-model="blog.title" autocomplete="off"></el-input>
</el-form-item>
<el-form-item label="时间" label-width="55px">
<el-date-picker
v-model="blog.time"
style="width: 100%;"
type="date"
value-format="yyyy-MM-dd"
placeholder="选择日期"
autocomplete="off">
</el-date-picker>
</el-form-item>
<el-form-item label="内容" label-width="55px">
<el-input v-model="blog.content" autocomplete="off" type="textarea" :rows="5"></el-input>
</el-form-item>
~~~
* 如下的属性设置了弹框底部的按钮以及点击事件
~~~
<div slot="footer" class="dialog-footer">
<el-button @click="formVisible = false">取 消</el-button>
<el-button type="primary" @click="submitBlog('blogForm')">确 定</el-button>
</div>
~~~
* 如下的属性设置了vue双向绑定所需要的参数
~~~
data() {
return {
// 是否显示
formVisible: false,
// dialog标题
dialogTitle: '',
// 列表数据
data: [],
// 选中的数据
multiSelection: [],
// 分页数据
page: {
pageSize: 10,
currentPage: 1,
total: 0
},
// 校验规则
rules: {
title: [
{required: true, message: '请输入标题', trigger: 'blur'},
]
},
// 表单映射模型
blog: {
id: '',
title: '',
content: '',
time: '',
}
}
},
~~~
* 如下方法定义了表单提交后执行的逻辑
~~~
submitBlog(formName) {
// 表单验证
this.$refs[formName].validate((valid) => {
if (valid) {
console.log(this.blog);
submit(this.blog).then(res => {
if (res.data.success) {
this.formVisible = false;
this.$message({
type: 'success',
message: '操作成功！'
})
} else {
this.$message({
type: 'error',
message: res.data.msg
})
}
})
}
})
},
~~~
3. 代码分析完毕，我们打开系统查看效果
4. 直接提交，发现校验成功
5. 填入相关数据，点击确定，查看控制台输出，发现打印信息正确
6. 因为采用了mock数据，所以是模拟数据，列表页无法新增数据。我们将在`开发进阶`章节采用前后端分离的模式进行真实数据交互演示
7. 下一章我们来学习下修改页如何操作
