[JavaScript知识库]Spa项目开发（动态树&数据表格&分页）

一、动态树

LeftNav.vue

<el-menu router :default-active="$route.path"? default-active="2" class="el-menu-vertical-demo" background-color="#334157" text-color="#fff"
??? active-text-color="#ffd04b" :collapse="collapsed">
??? <!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->
??? <div class="logobox">
????? <img class="logoimg" src="../assets/img/logo.png" alt="">
??? </div>
??? <el-submenu :key="'id_'+m.treeNodeId" :index="m.treeNodeId" v-for="m in menus">
????? <template slot="title">
??????? <i :class="m.icon"></i>
??????? <span>{{m.treeNodeName}}</span>
????? </template>
????? <!-- index里面填写的是路由跳转路劲 -->
????? <el-menu-item :key="'id_'+m2.treeNodeId" :index="m2.url" v-for="m2 in m.children">
??????? <i :class="m2.icon"></i>
??????? <span>{{m2.treeNodeName}}</span>
????? </el-menu-item>
??? </el-submenu>
? </el-menu>

<script>
? export default {
??? data() {
????? return {
??????? collapsed: false,
??????? //存放所有的一级菜单
??????? menus:[]
????? }
??? },
??? created() {
????? let url = this.axios.urls.SYSTEM_MENU_TREE;
????? this.axios.post(url, {}).then(res => { //代表成功?? 箭头函数 jdk8的语法
??????? console.log(res);
??????? this.menus=res.data.result;
????? }).catch(function(error) { //代表失败
??????? console.log(error);
????? });
????? //从总线上取出this.collapsed
????? this.$root.Bus.$on("collapsed-side", v => {
??????? this.collapsed = v;
????? });
??? }
? }
</script>

二、数据表格

在项目的src中创建views/sys目录，在此目录下创建Articles.vue文件

文件里添加如下代码

Articles.vue

<template>
  <div>
    <!--列表-->
    <el-table size="small" :data="listData" highlight-current-row v-loading="loading" border
      element-loading-text="拼命加载中" style="width: 100%;">
      <el-table-column align="center" type="selection" width="60">
      </el-table-column>
      <el-table-column sortable prop="id" label="编号" width="100">
      </el-table-column>
      <el-table-column sortable prop="title" label="文章标题" width="100">
      </el-table-column>
      <el-table-column sortable prop="body" label="文章内容" width="300">
      </el-table-column>
      <el-table-column align="center" label="操作" min-width="100">
        <template slot-scope="scope">
          <el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
          <el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>
  </div>
</template>

<script>
  export default {
    name: 'Articles',
    data() {
      return {
        listData: {}   
      }
    },
    created() {
     let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
     this.axios.post(url, param).then(res => {
       console.log(res);
       this.listData = res.data.result;
       this.formInline.total = res.data.pageBean.total;
     }).catch(function(error) {
       console.log(error);
     });
    }
  }
</script>

router/index.js

import Articles from '@/views/sys/Articles'

{
      path: '/AppMain',
      name: 'AppMain',
      component: AppMain,
      children: [{
          path: '/LeftNav',
          name: 'LeftNav',
          component: LeftNav
        },
        {
          path: '/TopNav',
          name: 'TopNav',
          component: TopNav
        },
        {
          path: '/sys/Articles',
          name: 'Articles',
          component: Articles
        }
      ]
    }

?运行后

三、分页

Articles.vue

<template>
  <div>
    <!-- 搜索筛选 -->
    <el-form :inline="true" :model="formInline" class="user-search">
      <el-form-item label="搜索：">
        <el-input size="small" v-model="formInline.title" placeholder="输入文章标题"></el-input>
      </el-form-item>
      <el-form-item>
        <el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
        <el-button size="small" type="primary" icon="el-icon-plus" @click="handleEdit()">添加</el-button>
      </el-form-item>
    </el-form>
    <!--列表-->
    <el-table size="small" :data="listData" highlight-current-row v-loading="loading" border
      element-loading-text="拼命加载中" style="width: 100%;">
     <!-- <el-table-column align="center" type="selection" width="60">
      </el-table-column> -->
      <el-table-column align="center" sortable prop="id" label="编号" width="100">
      </el-table-column>
      <el-table-column sortable prop="title" label="文章标题" width="100">
      </el-table-column>
      <el-table-column sortable prop="body" label="文章内容" width="300">
      </el-table-column>
      <el-table-column align="center" label="操作" min-width="100">
        <template slot-scope="scope">
          <el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
          <el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>
    <!-- 分页条 -->
    <el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
      :current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="100"
      layout="total, sizes, prev, pager, next, jumper" :total="formInline.total">
    </el-pagination>
  </div>
</template>

<script>
  export default {
    name: 'Articles',
    data() {
      return {
        listData: {},
        formInline: {
          page: 1,
          rows: 10,
          total: 0,
          title: ''
        }
      }
    },
    created() {
      this.dosearch({});
    },
    methods: {
      handleSizeChange(rows) {
        console.log("当前页查询数量为：" + rows);
        this.formInline.page = 1;
        this.formInline.rows = rows;
        this.search();
      },
      handleCurrentChange(page) {
        console.log("当前页为：" + page);
        this.formInline.page = page;
        this.search();
      },
      dosearch(param) {
        let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
        this.axios.post(url, param).then(res => {
          console.log(res);
          this.listData = res.data.result;
          this.formInline.total = res.data.pageBean.total;
        }).catch(function(error) {
          console.log(error);
        });
      },
      search() {
        this.dosearch(this.formInline);
      }
    }

  }
</script>

<style>
</style>
