前置要求：

1. vue+element-plus实现前端静态页面

HelloWorld.vue

<template><h2>hello界面</h2><div class="tableList"><!-- 搜索框 --><el-row :gutter="20"><el-col :span="8"><!-- 搜索与添加区域 --><el-input placeholder="请输入内容"v-model="SearchVal" clearable @clear="getUserList" @keyup.enter="enterSearch"><template #append><el-button @click="getUserList"><el-icon><search /></el-icon></el-button></template></el-input></el-col><el-col :span="2"><el-button type="primary" @click="openAdd">add</el-button></el-col><el-col :span="4"><el-button type="danger" @click="onDel">delete</el-button></el-col></el-row><!-- 表单 --><el-table :data="tableData" style="width: 100%"><el-table-column type="selection" width="55" /><el-table-column prop="date" label="Date" width="180" /><el-table-column prop="name" label="Name" width="100" /><el-table-column prop="oder" label="Oder" width="100" /><el-table-column prop="address" label="Address" /><!-- 操作按钮 --><el-table-column label="Operations"><template #default="scope"><el-button size="small" @click="handleEdit(scope.$index, scope.row)">Edit</el-button><el-buttonsize="small"type="danger"@click="handleDelete(scope.$index, scope.row)">Delete</el-button></template></el-table-column></el-table><el-pagination background layout="prev, pager, next" :total="total"  @current-change="handleCurrentChange"/></div>
</template><script lang="ts" setup >
import { ref } from "vue";
const SearchVal=ref("")
const total=ref(100)
const enterSearch=()=>{}
const openAdd=()=>{}
const onDel=()=>{}const handleEdit = (index: number, row: User) => {console.log(index, row)
}
const handleDelete = (index: number, row: User) => {console.log(index, row)
}const handleCurrentChange = (val: number) => {console.log(val)
}const tableData = [{date: '2016-05-03',name: 'Tom',oder:1,address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-02',name: 'Tom',oder:2,address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-04',name: 'Tom',oder:3,address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-01',name: 'Tom',oder:4,address: 'No. 189, Grove St, Los Angeles',},
]
</script><style lang="scss" scoped >
.tableList{margin:  0 500px;
}
.el-pagination{margin-top: 20px;
}
</style>

1.2 创建弹框组件app.vue

<!-- 弹窗组件 -->
<template><el-dialog v-model="dialogFormVisible" title="新增" with="30%"><el-form :model="form"><el-form-item label="时间" prop="date"><el-input v-model="form.data" type="date" placeholder="请选择一个时间" :disabledDate="disabledDate"/></el-form-item><el-form-item label="名称" prop="name"><el-input v-model="form.name"></el-input></el-form-item><el-form-item label="地址" prop="address"><el-input v-model="form.address"/></el-form-item><el-form-item label="排序" prop="order"><el-input v-model="form.oder"/></el-form-item></el-form><template #footer><span class="dialog-footer"><el-button @click="dialogFormVisible = false">Cancel</el-button><el-button type="primary" @click="dialogFormVisible = false">Confirm</el-button></span></template></el-dialog>
</template>
<script setup lang="ts">
import {ref} from "vue"const dialogFormVisible=ref(false)
const form=ref()
const disabledDate=(time:any)=>{//最大时间从今天开始const _maxTime=Date.now()-24*60*60*1000*1return time.getTime()<=_maxTime
}</script><style scoped lang="scss">
.dialog-footer button:first-child {margin-right: 10px;
}
.el-button--text {margin-right: 15px;
}
.el-select {width: 300px;
}
.el-input {width: 300px;
}
.dialog-footer button:first-child {margin-right: 10px;
}
</style>

完善方法组件的代码：组件的引用，组件的传值prop，计算属性，事件监听、子触发父组件的事件

HelloWorld.vue

<template><h2>hello界面</h2><div class="tableList"><!-- 搜索框 --><el-row :gutter="20"><el-col :span="8"><!-- 搜索与添加区域 --><el-input placeholder="请输入内容"v-model="SearchVal" clearable @clear="getUserList" @keyup.enter="enterSearch"><template #append><el-button @click="getUserList"><el-icon><search /></el-icon></el-button></template></el-input></el-col><el-col :span="2"><el-button type="primary" @click="openAdd">add</el-button></el-col><el-col :span="4"><el-button type="danger" @click="onDel">delete</el-button></el-col></el-row><!-- 表单 --><el-table :data="tableData" style="width: 100%"><el-table-column type="selection" width="55" /><el-table-column prop="date" label="Date" width="180" /><el-table-column prop="name" label="Name" width="100" /><el-table-column prop="order" label="Order" width="100" /><el-table-column prop="address" label="Address" /><!-- 操作按钮 --><el-table-column label="Operations"><template #default="scope"><el-button size="small" @click="handleEdit(scope.$index, scope.row)">Edit</el-button><el-buttonsize="small"type="danger"@click="handleDelete(scope.$index, scope.row)">Delete</el-button></template></el-table-column></el-table><el-pagination background layout="prev, pager, next" :total="total"  @current-change="handleCurrentChange"/></div><addVue :isShow="isShow" :info="info" @closeAdd="closeAdd" @success="success"></addVue>
</template><script lang="ts" setup >
import { ref } from "vue";
import User from "../class/User.ts"
import addVue from "../components/add.vue"
const SearchVal=ref("")
const total=ref(100)const isShow=ref(false)
//定义info
const info=ref<User>(new User())const enterSearch=()=>{}
const openAdd=()=>{isShow.value=true
}
const onDel=()=>{}const handleEdit = (index: number, row: User) => {console.log(index, row)info.value=rowisShow.value=true
}
const handleDelete = (index: number, row: User) => {console.log(index, row)
}const handleCurrentChange = (val: number) => {console.log(val)
}
const closeAdd=()=>{isShow.value=falseinfo.value=new User()
}
const success=()=>{isShow.value=falseinfo.value=new User()EIMessage.success(message)
}const tableData = [{date: '2016-05-03',name: 'Tom',order:1,address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-02',name: 'Tom',order:2,address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-04',name: 'Tom',order:3,address: 'No. 189, Grove St, Los Angeles',},{date: '2016-05-01',name: 'Tom',order:4,address: 'No. 189, Grove St, Los Angeles',},
]
</script><style lang="scss" scoped >
.tableList{margin:  0 500px;
}
.el-pagination{margin-top: 20px;
}
</style>

app.vue

作用：利用三元表达式，使用同一个组件展示不同的弹框内容

<!-- 弹窗组件 -->
<template><el-dialog v-model="dialogFormVisible" :title="info?.name?'修改':'新增'" with="30%" @close="$emit('closeAdd')" draggable="true"><!-- 使用三元表达式控制标题展示 --><el-form :model="form"><el-form-item label="时间" prop="date"><el-input v-model="form.date" type="date" placeholder="请选择一个时间" :disabledDate="disabledDate"/></el-form-item><el-form-item label="名称" prop="name"><el-input v-model="form.name"></el-input></el-form-item><el-form-item label="地址" prop="address"><el-input v-model="form.address"/></el-form-item><el-form-item label="排序" prop="order"><el-input v-model="form.order"/></el-form-item></el-form><template #footer><span class="dialog-footer"><el-button @click="closeAdd()">取消</el-button><el-button type="primary" @click="save()">确认</el-button></span></template></el-dialog>
</template>
<script setup lang="ts">
import {ref,Ref,computed,watch} from "vue"
import User from "../class/User"
const prop=defineProps({//内置的传参工具  接收使用prop传递过来的数据isShow:Boolean,//对于接收的类型进行控制info:User
})const disabledDate=(time:any)=>{//最大时间从今天开始const _maxTime=Date.now()-24*60*60*1000*1return time.getTime()<=_maxTime
}
const dialogFormVisible=computed(()=>prop.isShow)//表单的展示与隐藏绑定在isShow上
const form:Ref<User>=ref<User>({//声明使用User类id:"",date:"",name:"",address:"",order:0
})
watch(()=>prop.info,(newInfo)=>{if(newInfo){form.value={id:newInfo.id,date:newInfo.date,name:newInfo.name,address:newInfo.address,order:newInfo.order }}
})
const emits=defineEmits(["closeAdd","success"])
const closeAdd=()=>{emits("closeAdd")
}
const save=()=>{emits("success")
}</script><style scoped lang="scss">
.dialog-footer button:first-child {margin-right: 10px;
}
.el-button--text {margin-right: 15px;
}
.el-select {width: 300px;
}
.el-input {width: 300px;
