菜单功能实现
菜单接口封装
菜单管理是一个对菜单树结构的增删改查操作。
提供一个菜单查询接口,查询整颗菜单树形结构。
http/modules/menu.js 添加findMenuTree 接口。
import axios from '../axios' /* * 菜单管理模块 */ // 保存 export const save = (data) => { return axios({ url: '/menu/save', method: 'post', data }) } // 删除 export const batchDelete = (data) => { url: '/menu/delete', // 查找导航菜单树 export const findNavTree = (params) => { url: '/menu/findNavTree', method: 'get', params export const findMenuTree = () => { url: '/menu/findMenuTree', method: 'get'
菜单管理界面
菜单管理界面是使用封装的表格树组件显示菜单结构,并提供增删改查的功能。
Menu.vue
<template> <div class="container" style="width:99%;margin-top:-25px;"> <!--工具栏--> <div class="toolbar" style="float:left;padding-top:10px;padding-left:15px;"> <el-form :inline="true" :model="filters" :size="size"> <el-form-item> <el-input v-model="filters.name" placeholder="名称"></el-input> </el-form-item> <el-form-item> <kt-button label="查询" perms="sys:menu:view" type="primary" @click="findTreeData(null)"/> </el-form-item> <el-form-item> <kt-button label="新增" perms="sys:menu:add" type="primary" @click="handleAdd"/> </el-form-item> </el-form> </div> <!--表格树内容栏--> <el-table :data="tableTreeDdata" stripe size="mini" style="width: 100%;" v-loading="loading" element-loading-text="拼命加载中"> <el-table-column prop="id" header-align="center" align="center" width="80" label="ID"> </el-table-column> <table-tree-column prop="name" header-align="center" treeKey="id" width="150" label="名称"> </table-tree-column> <el-table-column header-align="center" align="center" label="图标"> <template slot-scope="scope"> <i :class="scope.row.icon || ''"></i> </template> </el-table-column> <el-table-column prop="type" header-align="center" align="center" label="类型"> <template slot-scope="scope"> <el-tag v-if="scope.row.type === 0" size="small">目录</el-tag> <el-tag v-else-if="scope.row.type === 1" size="small" type="success">菜单</el-tag> <el-tag v-else-if="scope.row.type === 2" size="small" type="info">按钮</el-tag> </template> </el-table-column> <el-table-column prop="parentName" header-align="center" align="center" width="120" label="上级菜单"> </el-table-column> <el-table-column prop="url" header-align="center" align="center" width="150" :show-overflow-tooltip="true" label="菜单URL"> </el-table-column> <el-table-column prop="perms" header-align="center" align="center" width="150" :show-overflow-tooltip="true" label="授权标识"> </el-table-column> <el-table-column prop="orderNum" header-align="center" align="center" label="排序"> </el-table-column> <el-table-column fixed="right" header-align="center" align="center" width="150" label="操作"> <template slot-scope="scope"> <kt-button label="修改" perms="sys:menu:edit" @click="handleEdit(scope.row)"/> <kt-button label="删除" perms="sys:menu:delete" type="danger" @click="handleDelete(scope.row)"/> </template> </el-table-column> </el-table> <!-- 新增修改界面 --> <el-dialog :title="!dataForm.id ?

}, // 删除 handleDelete (row) { this.$confirm('确认删除选中记录吗?', '提示', { type: 'warning' }).then(() => { let params = this.getDeleteIds([], row) this.$api.menu.batchDelete(params).then( res => { this.findTreeData() this.$message({message: '删除成功', type: 'success'}) }) }) }, // 获取删除的包含子菜单的id列表 getDeleteIds (ids, row) { ids.push({id:row.id}) if(row.children != null) { for(let i=0, len=row.children.length; i<len; i++) { this.getDeleteIds(ids, row.children[i]) } } return ids }, // 菜单树选中 handleTreeSelectChange (data, node) { this.dataForm.parentId = data.id this.dataForm.parentName = data.name }, // 图标选中 iconActiveHandle (iconName) { this.dataForm.icon = iconName }, // 表单提交 submitForm () { this.$refs['dataForm'].validate((valid) => { if (valid) { this.$confirm('确认提交吗?', '提示', {}).then(() => { this.editLoading = true let params = Object.assign({}, this.dataForm) this.$api.menu.save(params).then((res) => { if(res.code == 200) { this.$message({ message: '操作成功', type: 'success' }) } else { this.$message({message: '操作失败, ' + res.msg, type: 'error'}) } this.editLoading = false this.$refs['dataForm'].resetFields() this.dialogVisible = false this.findTreeData() }) }) } }) } }, mounted() { this.findTreeData() } } </script> <style scoped> </style>
其中对表格树组件进行了简单的封装。
views/Core/TableTreeColumn.vue
<template> <el-table-column :prop="prop" v-bind="$attrs"> <template slot-scope="scope"> <span @click.prevent="toggleHandle(scope.$index, scope.row)" :style="childStyles(scope.row)"> <i :class="iconClasses(scope.row)" :style="iconStyles(scope.row)"></i> {{ scope.row[prop] }} </span> </template> </el-table-column> </template> <script> import isArray from 'lodash/isArray' export default { name: 'table-tree-column', props: { prop: { type: String }, treeKey: { type: String, default: 'id' }, parentKey: { type: String, default: 'parentId' }, levelKey: { type: String, default: 'level' }, childKey: { type: String, default: 'children' } }, methods: { childStyles (row) { return { 'padding-left': (row[this.levelKey] * 25) + 'px' } }, iconClasses (row) { return [ !row._expanded ? 'el-icon-caret-right' : 'el-icon-caret-bottom' ] }, iconStyles (row) { return { 'visibility': this.hasChild(row) ? 'visible' : 'hidden' } }, hasChild (row) { return (isArray(row[this.childKey]) && row[this.childKey].length >= 1) || false }, // 切换处理 toggleHandle (index, row) { if (this.hasChild(row)) { var data = this.$parent.store.states.data.slice(0) data[index]._expanded = !data[index]._expanded if (data[index]._expanded) { data = data.splice(0, index + 1).concat(row[this.childKey]).concat(data) } else { data = this.removeChildNode(data, row[this.treeKey]) } this.$parent.store.commit('setData', data) this.$nextTick(() => { this.$parent.doLayout() }) } }, // 移除子节点 removeChildNode (data, parentId) { var parentIds = isArray(parentId) ? parentId : [parentId] if (parentId.length <= 0) { return data } var ids = [] for (var i = 0; i < data.length; i++) { if (parentIds.indexOf(data[i][this.parentKey]) !== -1 && parentIds.indexOf(data[i][this.treeKey]) === -1) { ids.push(data.splice(i, 1)[0][this.treeKey]) i-- } } return this.removeChildNode(data, ids) } } } </script>
测试效果
最终测试效果下图所示。
