Vue + Element UI 前端篇（十二）：用户管理模块

Vue + Element UI 实现权限管理系统 前端篇（十二）：用户管理模块 

用户管理模块

添加接口

在 http/moduls/user.js 中添加用户管理相关接口。

import axios from '../axios'

/* 
 * 用户管理模块
 */

// 保存
export const save = (params) => {
    return axios({
        url: '/user/save',
        method: 'post',
        params
    })
}// 删除
export const del = (params) => {
    return axios({
        url: '/user/delete',
        method: 'post',
        params
    })
}
// 分页查询
export const findPage = (params) => {
    return axios({
        url: '/user/findPage',
        method: 'post',
        params
    })
}

模拟数据

在 mock/moduls/user.js 中添加用户管理相关mock接口。

/* 
 * 用户管理模块
 */

// 保存
export function save() {
  return {
    url: 'http://localhost:8080/user/save',
    type: 'post',
    data: {
      "code": 200,
      "msg": null,
      "data": 1
    }
  }
}// 删除
export function del() {
  return {
    url: 'http://localhost:8080/user/delete',
    type: 'post',
    data: {
      "code": 200,
      "msg": null,
      "data": 1
    }
  }
}
// 分页查询
export function findPage() {
  return {
    url: 'http://localhost:8080/user/findPage',
    type: 'post',
    data: findPageData
  }
}

提取根路径

为了可以统一控制mock的开启与关闭，把mock的根路径提取出来。

 而具体的Mock接口，把根路径移除，因为在生成Mock的时候会自动把根路径加上去。

用户界面

用户管理界面主要是用户信息的表格展示，并提供基础的增删改查功能。

User.vue

<template>
  <div class="container" style="width:100%;">
    <!--工具栏-->
    <div class="toolbar" style="float:left; padding:18px;">

表格组件封装

为了可以实现表格的代码复用，封装表格组件。

src/views/Core/KtTable.vue

<template>
  <div>
    <!--表格栏-->
    <el-table :data="data.content" stripe highlight-current-row @selection-change="selectionChange" 
      :v-loading="loading" :max-height="maxHeight" :size="size" :align="align" style="width:100%;" >
      <el-table-column type="selection" width="40"></el-table-column>
      <el-table-column v-for="column in columns" 
        :prop="column.prop" :label="column.label" :width="column.width" :min-width="column.minWidth" 
        :sortable="column.sortable" :fixed="column.fixed" :key="column.prop" :type="column.type">
      </el-table-column>
      <el-table-column label="操作" width="150" fixed="right">
        <template slot-scope="scope">
          <kt-button label="编辑" :perms="permsEdit" :size="size" @click="handleEdit(scope.$index, scope.row)" />
          <kt-button label="删除" :perms="permsDelete" :size="size" type="danger" @click="handleDelete(scope.$index, scope.row)" />
        </template>
      </el-table-column>
    </el-table>
    <!--分页栏-->
    <div class="toolbar" style="padding:10px;">
      <kt-button label="批量删除" :perms="permsDelete" :size="size" type="danger" @click="handleBatchDelete()" 
        :disabled="this.selections.length===0" style="float:left;"/>
      <el-pagination layout="total, prev, pager, next, jumper" @current-change="refreshPageRequest" 
        :current-page="pageRequest.pageNum" :page-size="pageRequest.pageSize" :total="data.totalSize" style="float:right;">
      </el-pagination>
    </div>
  </div>
</template>

<script>
import KtButton from "@/views/Core/KtButton"
export default {
  name: 'KtTable',
  components:{
            KtButton
    },
  props: {
    columns: Array, // 表格列配置
    data: Object, // 表格分页数据
    permsEdit: String,  // 编辑权限标识
    permsDelete: String,  // 删除权限标识
    size: { // 尺寸样式
      type: String,
      default: 'mini'
    },
    align: {  // 文本对齐方式
      type: String,
      default: 'left'
    },
    maxHeight: {  // 表格最大高度
      type: Number,
      default: 420
    }
  },
  data() {
    return {
      // 分页信息
            pageRequest: {
                pageNum: 1,
        pageSize: 8
      },
      loading: false,  // 加载标识
      selections: []  // 列表选中列
    }
  },
  methods: {
    // 分页查询
    findPage: function () {
      this.$emit('findPage', {pageRequest:this.pageRequest})
    },
    // 选择切换
    selectionChange: function (selections) {
            this.selections = selections
    },
    // 换页刷新
        refreshPageRequest: function (pageNum) {
      this.pageRequest.pageNum = pageNum
      this.findPage()
    },
    // 编辑
        handleEdit: function (index, row) {
      this.$emit('handleEdit', {index:index, row:row})
        },
    // 删除
        handleDelete: function (index, row) {
            this.delete(row.id)
        },
        // 批量删除
        handleBatchDelete: function () {
            let ids = this.selections.map(item => item.id).toString()
            this.delete(ids)
        },
        // 删除操作
        delete: function (ids) {
            this.$confirm('确认删除选中记录吗？', '提示', {
                type: 'warning'
            }).then(() => {
                let params = []
                let idArray = (ids+'').split(',')
                for(var i=0; i<idArray.length; i++) {
                    params.push({'id':idArray[i]})
        }
        let callback = res => {
          this.$message({message: '删除成功', type: 'success'})
          this.findPage()
        }
        this.$emit('handleDelete', {params:params, callback:callback})
            }).catch(() => {
            })
        }
  },
  mounted() {
    this.refreshPageRequest(1)
  }
}
</script>

<style scoped>

</style>

权限按钮封装

为了可以实现对表格数据进行新增、编辑、删除操作按钮的权限控制，封装权限按钮组件。

src/views/Core/KtButton.vue

<template>
  <el-button :size="size" :type="type" 
    :loading="loading" :disabled="!hasPerms(perms)" @click="handleClick">
    {{label}}
  </el-button>
</template>

<script>
import { hasPermission } from '@/permission/index.js'
export default {
  name: 'KtButton',
  props: {
    label: {
      type: String,
      default: 'Button'
    },
    size: {
      type: String,
      default: 'mini'
    },
    type: {
      type: String,
      default: null
    },
    loading: {
      type: Boolean,
      default: false
    },
    disabled: {
      type: Boolean,
      default: false
    },
    perms: {
      type: String,
      default: null
    }
  },
  data() {
    return {
    }
  },
  methods: {
    handleClick: function () {
       this.$emit('click', {})
    }, 
    hasPerms: function (perms) {
       return hasPermission(perms) & !this.disabled
    }
  },
  mounted() {
  }
}
</script>

<style scoped>

</style>

测试效果

测试效果如下，增删改功能，mock不能实际操作数据库，可以结合本教程的后端代码一起测试。
