vue3 element-plus后台管理系统
搬砖狗-小强 人气:0菜单管理是一套系统中最常见最核心的系统管理模块之一,我把菜单管理分成了2个部分,左边可以管理维护菜单,在菜单的最右侧可以维护每个菜单按钮权限配置
使用element-plus el-tree组件快速开发树形菜单结构,el-tree组件中filter-node-method事件便可以实现树形菜单筛选过滤功能
<template> <div class="common-tree"> <el-tree :ref="treeRef" :data="treeData" :check-strictly="checkStrictly" show-checkbox :accordion="false" node-key="id" default-expand-all :highlight-current="true" :expand-on-click-node="false" @node-click="nodeClick" :filter-node-method="filterNode" empty-text="暂无数据" > <template #default="{ node, data }"> <span class="custom-tree-node"> <span style="margin-right: 15px;">{{ data.name }}</span> <slot :data="data" :node="node" /> </span> </template> </el-tree> </div> </template> <script> import { ref, reactive } from 'vue' import { returnStatement } from '@babel/types'; export default { name: 'CommonTree', props: { treeRef: { type: String, default: "treeRef" }, treeData: { type: Array, required: true, default () { return [] } }, checkStrictly: { type: Boolean, default () { return true } } }, setup(props, { emit }) { const nodeClick = (data, node, tree) => { emit('nodeClick', data, node, tree) } const filterNode = (value, data) => { if (!value) return true return data.label.includes(value) } return { nodeClick, filterNode } } } </script>
使用element-plus el-dialog、el-icon、el-form组件实现菜单新增编辑
el-dialog组件实现弹窗,选择图标功能,父组件通过v-model绑定变量,子组件通过emit('update语法糖实现父子组件属性快速传递
子组件代码:
<template> <el-dialog width="800px" v-model="visible" title="图标" :before-close="handleClose" > <ul class="iconUl"> <li v-for="icon in iconList" :key="icon"> <span :class="{'active':choosedIcon === icon}" @click="chooseIcon(icon)" @dblclick="confirm(icon)" > <el-icon style="width:48px;height: 48px;"><component class="icon" :is="icon" /></el-icon> </span> <p>{{ icon }}</p> </li> </ul> <template #footer> <span class="dialog-footer"> <el-button type="primary" @click="confirm(choosedIcon)">确认</el-button> <el-button @click="this.$emit('update:visible', false)">取消</el-button> </span> </template> </el-dialog> </template> <script> import { ref, reactive } from 'vue' import * as IconsModule from '@element-plus/icons-vue' export default { name: 'Icons', props: { visible: { type: Boolean, default: false } }, setup(props, { emit }) { const iconList = ref([]) const choosedIcon = ref(null) for (var key in IconsModule) { iconList.value.push(IconsModule[key].name) } const chooseIcon = (icon) => { choosedIcon.value = icon } const confirm = (icon) => { emit('update:icon', icon) emit('update:visible', false) } const handleClose = (done) => { emit('update:visible', false) } return { iconList, choosedIcon, chooseIcon, confirm, handleClose } } }
父组件代码:
<icons v-model:visible="dialogIconVisible" v-model:icon="menu.icon" />
使用element-plus el-table组件实现菜单按钮权限配置
菜单按钮权限配置表格部分代码:
<el-table ref="resourceTableKey" :data="resource.tableData.records" stripe empty-text="暂无数据" :header-cell-style="{background:'#FCFBFF',border:'0'}" style="width: 100%" @selection-change="resourceSelectChange" > <el-table-column type="selection" width="40" /> <el-table-column label="编码" width="80" show-overflow-tooltip> <template #default="scope">{{ scope.row.code }}</template> </el-table-column> <el-table-column label="名称" width="80" show-overflow-tooltip> <template #default="scope">{{ scope.row.name }}</template> </el-table-column> <el-table-column label="请求方式" width="80" show-overflow-tooltip> <template #default="scope">{{ scope.row.method }}</template> </el-table-column> <el-table-column label="请求地址" width="80" show-overflow-tooltip> <template #default="scope">{{ scope.row.url }}</template> </el-table-column> <el-table-column label="操作" width="140"> <template #default="scope"> <el-button type="primary" size="small" @click="resourceEdit(scope.$index, scope.row)" >修改</el-button > <el-button type="danger" size="small" @click="resourceSingleDelete(scope.$index, scope.row)" >删除</el-button > </template> </el-table-column> </el-table> // ----------------------编辑菜单按钮权限配置---------------------------- <script> const resourceTableKey = ref(null) const resource = reactive({ queryParams: { code: null, name: null, menuId: null }, tableData: { total: 2, records: [] }, pagination: { size: 10, current: 1 }, formData: {}, selection: [] }) const resourceSearch = () => { getResourceList().then(data => { resource.tableData.records = data.data }) } const resourceAdd = () => { dialogEditVisible.value = true resource.formData = {} } const resourceEdit = (index, row) => { dialogEditVisible.value = true resource.formData = row } const resourceSingleDelete = (index, row) => { ElMessageBox.confirm('确认删除?', '确认删除', { confirmButtonText: '确认', cancelButtonText: '取消', confirmButtonClass: 'confirmButton', type: 'warning', }) .then(() => { resource.tableData.records.splice(index, 1) }) .catch(() => { }) } const resourceSelectChange = (selection) => { resource.selection = selection } const resourceBatchDelete = () => { if (!resource.selection.length) { ElMessageBox.alert('请选择要删除项!', '提示', { confirmButtonText: '确认', type: 'warning' }) return } ElMessageBox.confirm('确认删除?', '确认删除', { confirmButtonText: '确认', cancelButtonText: '取消', type: 'warning', }) .then(() => { resource.tableData.records = resource.tableData.records.filter(function(items){ return (resource.selection.filter(function(selectionItems){ return selectionItems.id == items.id })).length == 0 }) }) .catch(() => { }) } const resourceReturn = { resourceTableKey, resource, resourceEdit, resourceAdd, resourceSingleDelete, resourceSelectChange, resourceBatchDelete } </script> // ----------------------编辑菜单按钮权限配置----------------------------
菜单按钮权限配置表单部分代码:
<template> <el-dialog width="800px" v-model="visible" title="修改" :before-close="handleClose" > <el-form ref="form" :model="fromData" label-position="right" label-width="100px"> <el-form-item label="编码" prop="code"> <el-input v-model="fromData.code" /> <p class="note">建议使用:作为分隔符,并以view、add、update、delete、export、import、download、upload等关键词结尾</p> <p class="note">如:menu:add、 resource:view、 file:upload</p> </el-form-item> <el-form-item label="名称" prop="name"> <el-input v-model="fromData.name" /> </el-form-item> <el-form-item label="请求方式" prop="describe" > <el-input v-model="fromData.method" /> </el-form-item> <el-form-item label="请求地址" prop="describe" > <el-input v-model="fromData.url" /> </el-form-item> <el-form-item label="描述" prop="describe" > <el-input v-model="fromData.describe" /> </el-form-item> </el-form> <template #footer> <span class="dialog-footer"> <el-button type="primary" @click="confirm()">确认</el-button> <el-button @click="this.$emit('update:visible', false)" >取消</el-button> </span> </template> </el-dialog> </template> <script> import { ref, reactive, watch } from 'vue' import { returnStatement } from '@babel/types'; export default { name: 'edit', props: { visible: { type: Boolean, default: false }, resource: { type: Object, default: () => ({}) } }, setup(props, { emit }) { const fromData = reactive({}) watch(() => props.resource, (newResource) => { for (const key in fromData) { fromData[key] = '' } for (const key in newResource) { fromData[key] = newResource[key] } }, { immediate: true }) const confirm = () => { for (const key in fromData) { props.resource[key] = fromData[key] } emit('update:visible', false) } const handleClose = (done) => { emit('update:visible', false) } return { confirm, handleClose, fromData } } } </script>
