前语
直至今天,看了一下他人写的代码,才发现以前自己写的代码太废物,所以在这次做的一个后台项目中,采用他的代码风格,怎样说呢,复用性特别好,封装的很好,学到很多,所以记载一下思路,我以为这个封装思路是真的很棒,写第一个页面的时候可能会费事一些,可是后边只要是类似的页面,事半功倍,直接CV改装备项就好了,是真的顶,记载一下,学习一下,我这儿用的是vue3+ts
Form表单的封装
简述
这儿是Form表单部分,下面是完好的思路,最后有附上完好的代码,大佬能够直接看完好的代码就能看懂了,小白们跟着我的思路估计能看懂….
正常的运用
假如咱们正常运用组件库里边的组件会是这样的
代码如下
role.vue页面组件
<template>
<div class="role">
<el-form>
<el-form-item label="用户id">
<el-input placeholder="请输入用户id"></el-input>
</el-form-item>
<el-form-item label="用户名">
<el-input placeholder="请输入用户名"></el-input>
</el-form-item>
<el-form-item label="实在名字">
<el-input placeholder="请输入实在名字"></el-input>
</el-form-item>
<el-form-item label="用户名">
<el-input placeholder="请输入用户名"></el-input>
</el-form-item>
<el-form-item label="电话号码">
<el-input placeholder="请输入电话号码"></el-input>
</el-form-item>
<el-form-item label="用户状况">
<el-select placeholder="请挑选用户状况">
<el-option label="禁用" value="0"></el-option>
<el-option label="启用" value="1"></el-option>
</el-select>
</el-form-item>
<el-form-item label="创立时刻">
<el-date-picker
startPlaceholder="开端时刻"
endPlaceholder="结束时刻"
type="daterange"
></el-date-picker>
</el-form-item>
</el-form>
</div>
</template>
<script setup lang="ts"></script>
<style scoped lang="less"></style>
这时咱们能够加点款式让他变得美观,并且布局也变一变就能够变成这样,当然款式布局能够自界说
代码如下
role.vue页面组件
<template>
<div class="role">
<el-form labelWidth="120px">
<el-row>
<el-col :span="8">
<el-form-item
label="用户id"
:style="{
padding: '10px 20px'
}"
>
<el-input placeholder="请输入用户id"></el-input>
</el-form-item>
</el-col>
<el-col :span="8">
<el-form-item
label="用户名"
:style="{
padding: '10px 20px'
}"
>
<el-input placeholder="请输入用户名"></el-input>
</el-form-item>
</el-col>
<el-col :span="8">
<el-form-item
label="实在名字"
:style="{
padding: '10px 20px'
}"
>
<el-input placeholder="请输入实在名字"></el-input>
</el-form-item>
</el-col>
<el-col :span="8">
<el-form-item
label="电话号码"
:style="{
padding: '10px 20px'
}"
>
<el-input placeholder="请输入电话号码"></el-input>
</el-form-item>
</el-col>
<el-col :span="8">
<el-form-item
label="用户状况"
:style="{
padding: '10px 20px'
}"
>
<el-select placeholder="请挑选用户状况">
<el-option label="禁用" value="0"></el-option>
<el-option label="启用" value="1"></el-option>
</el-select>
</el-form-item>
</el-col>
<el-col :span="8">
<el-form-item
label="创立时刻"
:style="{
padding: '10px 20px'
}"
>
<el-date-picker
startPlaceholder="开端时刻"
endPlaceholder="结束时刻"
type="daterange"
></el-date-picker>
</el-form-item>
</el-col>
</el-row>
</el-form>
</div>
</template>
<script setup lang="ts"></script>
<style scoped lang="less">
.el-form-item {
margin-top: 18px;
}
.el-select {
width: 100%;
}
</style>
开端封装①
这时咱们就能够开端封装了,假如咱们能够经过传装备项的办法来控制款式和form表单项的类型和个数的话,是不是变得很便利,下次直接传装备项用就好了?话不多说直接上图上代码
能够看到作用相同,代码却简洁了,模板里边不会呈现大量重复的代码了
role.vue页面组件
<template>
<div class="role">
<el-form :labelWidth="searchFormConfig.labelWidth">
<el-row>
<template v-for="item in searchFormConfig.formItems" :key="item.label">
<el-col :span="8">
<el-form-item
:label="item.label"
:style="searchFormConfig.itemStyle"
>
<template
v-if="item.type === 'input' || item.type === 'password'"
>
<el-input
:placeholder="item.placeholder"
:show-password="item.type === 'password'"
></el-input>
</template>
<template v-else-if="item.type === 'select'">
<el-select :placeholder="item.placeholder">
<el-option
v-for="option in item.options"
:key="option.value"
:label="option.label"
:value="option.value"
></el-option>
</el-select>
</template>
<template v-else>
<el-date-picker v-bind="item.otherOptions"></el-date-picker>
</template>
</el-form-item>
</el-col>
</template>
</el-row>
</el-form>
</div>
</template>
<script setup lang="ts">
// 界说表单装备项
const searchFormConfig = {
formItems: [
{
type: 'input',
label: '用户id',
placeholder: '请输入用户id'
},
{
type: 'input',
label: '用户名',
placeholder: '请输入用户名'
},
{
type: 'input',
label: '实在名字',
placeholder: '请输入实在名字'
},
{
type: 'input',
label: '电话号码',
placeholder: '请输入电话号码'
},
{
type: 'select',
label: '用户状况',
placeholder: '请挑选用户状况',
options: [
{
label: '禁用',
value: 0
},
{
label: '启用',
value: 1
}
]
},
{
type: 'datepicker',
label: '创立时刻',
otherOptions: {
startPlaceholder: '开端时刻',
endPlaceholder: '结束时刻',
type: 'daterange',
'unlink-panels': true
}
}
],
labelWidth: '120px',
itemStyle: {
padding: '10px 20px'
},
itemColLayout: {
span: 8
}
}
</script>
<style scoped lang="less">
.el-form-item {
margin-top: 18px;
}
.el-select {
width: 100%;
}
</style>
开端封装②
这时它复用的锥形现已有了,咱们能够将装备项抽出去,并给它一些类型约束,把这部分运用表单的代码抽出去,封装成form组件,这样之后咱们在用的时候,直接用这个组件然后给它传装备项就能够了
1.装备项类型约束文件(不用ts的话就没有,不想约束悉数给any类型随意,我这儿是为了让代码严谨一丢丢哈哈)
type IFormType = 'input' | 'password' | 'select' | 'datepicker'
interface IFormOption {
label: string
value: string | number
}
export interface IFormItem {
type: IFormType //输入框类型
label: string //输入框标题
placeholder?: any //输入框默许显现内容
// 针对select
options?: IFormOption[] //挑选器的可选子选项
// 针对特殊特点
otherOptions?: any
}
export interface IForm {
formItems: IFormItem[]
labelWidth?: string
itemStyle?: any
itemColLayout?: any
}
2.装备项文件
import { IForm } from '@/base-ui/form/type'
export const searchFormConfig: IForm = {
formItems: [
{
type: 'input',
label: '用户id',
placeholder: '请输入用户id'
},
{
type: 'input',
label: '用户名',
placeholder: '请输入用户名'
},
{
type: 'input',
label: '实在名字',
placeholder: '请输入实在名字'
},
{
type: 'input',
label: '电话号码',
placeholder: '请输入电话号码'
},
{
type: 'select',
label: '用户状况',
placeholder: '请挑选用户状况',
options: [
{ label: '启用', value: 1 },
{ label: '禁用', value: 0 }
]
},
{
type: 'datepicker',
label: '创立时刻',
otherOptions: {
startPlaceholder: '开端时刻',
endPlaceholder: '结束时刻',
type: 'daterange'
}
}
],
labelWidth: '120px',
itemColLayout: {
span: 8
},
itemStyle: {
padding: '10px 20px'
}
}
3.form表单文件
留意:在这儿,我将labelWidth,itemColLayout,itemStyle设置了默许值,所以我上面的那些款式装备项能够不传,默许便是我设置的那些值,假如需求其他款式能够传入修正,不要款式能够传个空进去,这儿我还加了两个插槽,增加可扩展性
<template>
<div class="header">
<slot name="header"> </slot>
</div>
<el-form ref="ruleFormRef" :labelWidth="labelWidth">
<el-row>
<template v-for="item in formItems" :key="item.label">
<el-col v-bind="itemColLayout">
<el-form-item
v-if="!item.isHidden"
:label="item.label"
:style="itemStyle"
:prop="item.field"
>
<template v-if="item.type === 'input' || item.type === 'password'">
<el-input
:placeholder="item.placeholder"
:show-password="item.type === 'password'"
></el-input>
</template>
<template v-else-if="item.type === 'select'">
<el-select :placeholder="item.placeholder">
<el-option
v-for="option in item.options"
:key="option.label"
:label="option.label"
:value="option.value"
></el-option>
</el-select>
</template>
<template v-if="item.type === 'datepicker'">
<el-date-picker v-bind="item.otherOptions"></el-date-picker>
</template>
</el-form-item>
</el-col>
</template>
</el-row>
</el-form>
<div class="footer">
<slot name="footer"></slot>
</div>
</template>
<script setup lang="ts">
import { defineProps, withDefaults } from 'vue'
import { IFormItem } from './type'
interface Prop {
formItems: IFormItem[] // 表单装备项
labelWidth?: string // 每个表单标题宽度
itemStyle?: object // 每个表单款式
itemColLayout?: object // 表单布局
isHidden?: boolean // 该输入框是否躲藏
}
const props = withDefaults(defineProps<Prop>(), {
labelWidth: '120px',
itemColLayout: () => ({
xl: 6, // >=1920px
lg: 8, // >=1200px
md: 12, // >=992px
sm: 24, // >=768px
xs: 24 // <768px
}),
itemStyle: () => ({
padding: '10px 20px'
})
})
</script>
<style scoped>
.el-form-item {
margin-top: 18px;
}
.el-select {
width: 100%;
}
</style>
4.role.vue页面组件
<template>
<div class="role">
<form-test v-bind="searchFormConfig"></form-test>
</div>
</template>
<script setup lang="ts">
import formTest from '@/base-ui/form/form-test.vue'
import { searchFormConfig } from './config/search-config-test'
</script>
<style scoped lang="less"></style>
这时现已开端封装好了,咱们能够运用一下看作用,咱们能够看到款式跟之前完全相同,可是页面的代码量就那么点,要用的话直接用咱们封装好的form组件然后传入装备项就出来了
它的可扩展性也是很强的,比方:
这儿咱们把款式装备项悉数传空值,然后装备项也传一个,它又变成原来最丑的姿态了,证明咱们是能够随意更改它的款式和布局,只需求经过传入装备项更改就能够了,便利
装备项文件
import { IForm } from '@/base-ui/form/type'
export const searchFormConfig: IForm = {
formItems: [
{
field: 'id',
type: 'input',
label: '用户id',
placeholder: '请输入用户id'
}
],
labelWidth: '',
itemColLayout: {},
itemStyle: {}
}
其实到这儿还没结束,由于这时的表单还输入不了东西,由于咱们根本就没给它的输入框绑定值,所以咱们要在装备项传入多一个field字段,它能够作为输入框绑定的值
开端封装③
这儿仅仅是给装备项中增加field字段(留意假如用了ts的还要去type文件里边给咱们界说的IFormItem接口增加一个field字段)
装备项文件
import { IForm } from '@/base-ui/form/type'
export const searchFormConfig: IForm = {
formItems: [
{
field: 'id',
type: 'input',
label: '用户id',
placeholder: '请输入用户id'
},
{
field: 'name',
type: 'input',
label: '用户名',
placeholder: '请输入用户名'
},
{
field: 'realname',
type: 'input',
label: '实在名字',
placeholder: '请输入实在名字'
},
{
field: 'cellphone',
type: 'input',
label: '电话号码',
placeholder: '请输入电话号码'
},
{
field: 'enable',
type: 'select',
label: '用户状况',
placeholder: '请挑选用户状况',
options: [
{ label: '启用', value: 1 },
{ label: '禁用', value: 0 }
]
},
{
field: 'createAt',
type: 'datepicker',
label: '创立时刻',
otherOptions: {
startPlaceholder: '开端时刻',
endPlaceholder: '结束时刻',
type: 'daterange'
}
}
],
labelWidth: '120px',
itemColLayout: {
span: 8
},
itemStyle: {
padding: '10px 20px'
}
}
由于传入了fied字段,所以咱们要搜集一切的field字段,组成formData数据,传入表单组件,formData里边的每个子项分别作为每个输入框绑定的值
留意:这儿有两个难点
难点一:
咱们传进去的数据在里边是要做修正传出来的,而vue的准则是单项数据流传输,咱们不能直接将数据传进去(其实事实能够这样做,可是违背了单向数据流传输准则,咱们尽量不违背哈),所以咱们采用v-model的办法将formData传入form组件,这样做的话便是双向断定了,不算违背嘿嘿
难点二:由于咱们传进去的formData的数据,并不是在form组件里边用的,而是要绑定到form组件里边的element puls的输入框里边的,所以咱们在form组件里边接纳到formData数据,然后在把formData它的各个子项v-model绑定到输入框里边,可是这样会报错,不能直接用v-model,这儿就需求知道v-model是怎样实现的了,咱们在这儿是直接把接纳到的formData数据绑定到输入框里边的,在form组件并没有界说formData这个变量,所以不能直接用v-model的办法,这了可能有点懵,举个例子
(比方你将一个值test用v-model传入一个input的框,你输入框输入数据,你的test是会同步改动,也便是说,v-model会把你修正后的值传出来赋值给你的test,而在这儿,咱们将formData用v-model绑定到输入框,输入框值改动,正常来说它会将修正后的值赋值给咱们传进去的formData,可是咱们不能让它直接赋值给咱们的formData,由于咱们的formData也是从其他组件传进来的,所以咱们要把修正后的值再次传出去到传进来formData数据的那个组件中,而不是直接就赋值,这时咱们就要用到v-model的原始写法了,其实v-model是个语法糖来的)

let formDataInit = {}

这时咱们发现它能够拿到数据了,很nice,其实这差不多现已算封装好了,能够经过装备项修正里边的东西了,一起也能够拿到数据,可是我这个项目不止于此,我这其实要做表单的查询的,所以我要改装一下变成这样
其实便是加了两个插槽和两个办法,我这儿要实现功用便是点击重置按钮,它会重置表单数据,点击查找按钮就能够拿到表单数据,这样咱们就能够用咱们拿到的表单数据去进行咱们的操作拉,所以上代码
role.vue组件
该部分咱们传入了两个template,一个是标题:高档检索,一个是两个按钮
这儿要重置按钮重置表单数据,取到表单的ref调用resetFields办法就好了,然后点击查找按钮能够打印出formData数据,然后咱们就能够使用该数据去做咱们想要做的操作了,例如查询列表数据等
<template>
<div class="role">

let queryInfo = { ...formData.value }

queryInfo[item.field] = Number(queryInfo[item.field])
}

resetForm
})
</script>
<style scoped>

</style>
1.该组件要增加表单重置的办法
2.把formData的值绑定到form表单上:model=‘formData’
3.给el-form-item加上prop特点
2,3假如不加上的话,表单内置的重置表单办法会失效
这时咱们现已封装完成了,可是咱们能够发现,咱们的role组件东西有点多了,假如咱们其他组件比方,user组件等,都要用这样类似的布局,咱们这时就又要把这一堆代码给cv一遍,所以咱们有能够把role里边这堆东西再封装一次

作用图
这儿咱们就能够体会到了,相同的作用,role里边的代码是这么的少,只需求传入装备项就能够搞出这个表单,并且还能拿到表单数据,并且重点是,下个页面再用这个布局,直接用page-search组件就能够了,只需求传入不同的装备项,假如不同布局,再封装另一个page-search便是了,可是这是后台耶?搞那么富丽呼哨?不便是查找表单,展现表单么

结语
写了这么多,终于写完了,这儿是归于Form表单部分的封装悉数进程,能写到这其实我挺有成就感的哈哈哈哈,由于我刚学会的时候思路有了,可是敲出来有点困难,不过这个进程是我又捋了一遍,然后自己敲出来的,感觉其实也不难,现已把握了这种封装思路与办法了哈哈,其他组件其实也能够使用这种思路,封装出来,在页面上的运用直接传装备项调用就完事,开发每个类似的页面功率简直是牛逼
Table表格的封装
简述
再来折磨一遍,这儿是table表单的封装,其实跟上面的差不多,有点小差异,会用到增加动态插槽,这儿就不墨迹了,直接上用装备项封装前的正常运用
正常运用
user.vue
<template>
<div class="user">
<el-table style="width: 100%" :data="dataList" border>
<!-- 1.传入showSelectColumn时展现的全选列 -->
<template v-if="contentTableConfig.showSelectColumn">
<el-table-column type="selection" />
</template>
<!-- 2.传入showIndexColumn时展现的序号列 -->
<template v-if="contentTableConfig.showIndexColumn">
<el-table-column type="index" label="序号" />
</template>
<!-- 3.propList里边的一切列 -->
<template v-for="item in contentTableConfig.propList" :key="item.prop">
<el-table-column v-bind="item" show-overflow-tooltip>
<!-- 传有slotName时展现的插槽列 -->
<template #default="scope" v-if="item.slotName">
<template v-if="item.slotName === 'handler'">
<el-button size="small" :icon="Edit" type="text">修改</el-button>
<el-button size="small" :icon="Delete" type="text"
>删去</el-button
>
</template>
<template v-if="item.slotName === 'status'">
<el-button>{{
scope.row.status === 0 ? '禁用' : '启用'
}}</el-button>
</template>
</template>
</el-table-column>
</template>
</el-table>
</div>
</template>
<script setup lang="ts">
import { Delete, Edit } from '@element-plus/icons-vue'
import { useStore } from '@/store'
import { computed } from 'vue'
const store = useStore()
// 这儿是网络恳求数据
const getPageData = () => {
store.dispatch(`main/getPageListAction`, {
queryInfo: {
offset: 0,
size: 10
},
pageName: 'users'
})
}
// 页面加载时第一次调用获取表单数据
getPageData()
const dataList = computed(() => store.getters[`main/pageListData`]('users'))
// 表格装备项
const contentTableConfig = {
// 表格装备
propList: [
{ prop: 'id', label: '用户id', minWidth: '100', align: 'center' },
{ prop: 'name', label: '用户名', minWidth: '100', align: 'center' },
{ prop: 'realname', label: '实在名字', minWidth: '100', align: 'center' },
{ prop: 'cellphone', label: '手机号码', minWidth: '100', align: 'center' },
{
prop: 'enable',
label: '状况',
minWidth: '100',

align: 'center'
}
],
// 表格具有序号列
showIndexColumn: true,
// 表格具有可选列
showSelectColumn: true
}
</script>
<style scoped lang="less"></style>
从上面能够看出,主页面的代码有多冗余,看到就头疼+裂开,所以开端一层封装

const props = withDefaults(defineProps<Props>(), {

能够看到,代码抽出去了,可是咱们能够发现,里边的插槽其实不能给它写死,应该是动态决议的,所以咱们能够这样做
在拥有slotName部分的插槽列部分放入一个签字插槽,再将默许插槽列中的scope.row发回给签字插槽
table.vue(为了可扩展性,我仍旧在里边加了两个插槽,一个顶部一个底部)
<template>
<div class="header">
<slot name="header"> </slot>
</div>
<el-table style="width: 100%" :data="listData" border>
<!-- 1.传入showSelectColumn时展现的全选列 -->
<template v-if="showSelectColumn">
<el-table-column type="selection" />
</template>
<!-- 2.传入showIndexColumn时展现的序号列 -->

<el-table-column type="index" label="序号" />
</template>
<!-- 3.propList里边的一切列 -->
<template v-for="item in propList" :key="item.prop">
<el-table-column v-bind="item" show-overflow-tooltip>
<!-- 传有slotName时展现的插槽列 -->
<template #default="scope" v-if="item.slotName">
<slot :name="item.slotName" :row="scope.row"></slot>
</template>
</el-table-column>
</template>
</el-table>
<div class="footer">
<slot name="footer"> </slot>
</div>
</template>
<script setup lang="ts">
import { defineProps, withDefaults, defineEmits } from 'vue'
import { ITbaleOption } from './type'
interface Props {
listData: any[] //表单数据
propList: ITbaleOption[] //表单装备项
showIndexColumn?: boolean //是否显现索引列
showSelectColumn?: boolean //是否显现全选列

}
const props = withDefaults(defineProps<Props>(), {
showIndexColumn: false,
showSelectColumn: false,
childrenProps: () => ({})
})
</script>
<style scoped></style>
然后在user.vue中放入签字插槽,传进去table组件里,一起传入一些内容到可扩展插槽里边
user.vue
<template>
<div class="user">
<div class="content">
<table-test v-bind="contentTableConfig" :listData="dataList">
<!-- 1.header中的插槽 -->

<div class="header-default">
<!-- 传入标题(坐落左边) -->
<div class="title">用户列表</div>
<!-- 传入处理内容(坐落右侧) -->
<div class="handler">
<el-button type="primary" @click="addUserBtnClick"
>新建用户</el-button
>
</div>
</div>
</template>
<!-- 2.该user页面独有部分 -->
<template #status="scope">
<el-button>{{ scope.row.status === 0 ? '禁用' : '启用' }}</el-button>
</template>
<!-- 3.每个页面都会有的部分 -->
<template #handler="scope">

<!-- 4.footer插槽 -->

显然此刻封装现已满意需求了,可是咱们发现主页面的代码页还是比较冗余,假如不用到插槽的话还好,要用到插槽的话,就要在主页面写入很多插槽,多个页面都这样的话页裂开,所以咱们要像之前相同把这坨代码再封一层

图中能够看出作用其实是相同的,主页面的代码少了,只需求传入装备项和pageName(控制网络恳求数据)就能够生成一个表格,可是咱们能够发现,假如多个页面复用的话,其实操作列的插槽是公有的,可是状况列却是私有的,其他页面不一定有状况页,所以状况列内容插入的位置应该在主页面user里边而不该在封装的组件里边,并且修改新建逻辑也是页面独有,应该在主页面履行
开端封装③
user.vue
<template>
<div class="user">
<div class="content">
<page-table
:contentTableConfig="contentTableConfig"
pageName="users"
@editBtnClick="handleEditClick"
@createBtnClick="handleCreateClick"
>
<template #status="scope">
<el-button>{{ scope.row.status === 0 ? '禁用' : '启用' }}</el-button>
</template>
</page-table>
</div>
</div>

<script setup lang="ts">
// 导入表单装备项
import { contentTableConfig } from './config/table-config'
import pageTable from '@/components/page-table/page-table-test.vue'
const handleEditClick = (row: any, pageNameInChinese: any) => {
console.log('点击了修改按钮,数据为:', row, pageNameInChinese)
}
const handleCreateClick = (pageNameInChinese: any) => {
console.log('点击了新建用户,数据为:', pageNameInChinese)
}
</script>
<style scoped lang="less">
.content {
border-top: 20px solid #dedee1;
padding: 40px;
}
</style>
page-table.vue
<template>
<table-test v-bind="contentTableConfig" :listData="dataList">
<!-- 1.header中的插槽 -->
<template #header>
<div class="header-default">
<!-- 传入标题(坐落左边) -->
<div class="title">{{ pageNameInChinese }}列表</div>
<!-- 传入处理内容(坐落右侧) -->
<div class="handler">
<el-button type="primary" @click="addUserBtnClick"
>新建{{ pageNameInChinese }}</el-button
>

</div>
</template>
<!-- 2.该user页面独有部分 -->
<template
v-for="item in otherPropSlots"
:key="item.prop"
#[item.slotName]="scope"
>
<template v-if="item.slotName">
<slot :name="item.slotName" :row="scope.row"></slot>
</template>
</template>
<!-- 3.每个页面都会有的部分 -->
<template #handler="scope">

>修改</el-button
>
<el-button

<!-- 4.footer插槽 -->
<template #footer>

import tableTest from '@/base-ui/table/table-test.vue'
import type { ITable } from '@/base-ui/table/type'
import { useStore } from '@/store'
import { defineProps, computed, defineEmits } from 'vue'
// 界说特点
interface Props {
contentTableConfig: ITable //表单装备接纳
pageName: string //表单名字接纳
}
const props = defineProps<Props>()
const emit = defineEmits<{
(e: 'createBtnClick', pageNameInChinese: string): void
(e: 'editBtnClick', rowData: any, pageNameInChinese: string): void
}>()
const store = useStore()
// 这儿是网络恳求数据
const getPageData = () => {
store.dispatch(`main/getPageListAction`, {
queryInfo: {
offset: 0,
size: 10
},
pageName: props.pageName
})
}
// 页面加载时第一次调用获取表单数据
getPageData()
const dataList = computed(() =>
store.getters[`main/pageListData`](props.pageName)
)
// 1.获取页面中文名称
const pageNameTransform = (pageName: string): string => {
switch (pageName) {
case 'users':
return '用户'
default:
return ''
}
}
const pageNameInChinese = pageNameTransform(props.pageName)
// 2.归于动态插槽的装备项筛选
const otherPropSlots: any = props.contentTableConfig?.propList.filter(
(item: any) => {
if (item.slotName === 'handler') return false
return item.slotName
}
)
// 点击修改按钮触发事情
const handleEditClick = (row: any) => {
emit('editBtnClick', row, pageNameInChinese)
}
// 点击删去按钮触发事情
const deleteBtnClick = (row: any) => {
console.log('点击了删去按钮,数据为:', row)
}
// 点击新建用户触发事情
const addUserBtnClick = () => {
emit('createBtnClick', pageNameInChinese)
}
</script>
<style scoped lang="less">
.header-default {
display: flex;
justify-content: space-between;
align-items: center;
margin-bottom: 20px;
.title {
font-size: 22px;
font-weight: 700;
}
}
.footer-default {
display: flex;
justify-content: flex-end;
margin-top: 20px;
}
</style>
能够看到,这时咱们现已把独有私有的插槽区别开了,并且修改和新建的逻辑也在主页面中履行,封装结束,下面附上完好代码
