SPA项目开发之动态树+数据表格+分页

一、动态树功能实现

1、要确定静态树形菜单节点的样式排版

2、要获取树形节点的数据

一、动态树功能实现

1、要确定静态树形菜单节点的样式排版

  <el-submenu index="1-4">
      <template slot="title">
        <i class="el-icon-location"></i>
        <span>一级菜单</span>
      </template>
      <el-menu-item index="1-4-1">
        <i class="el-icon-location"></i>
        <span>二级菜单</span>
      </el-menu-item>
    </el-submenu>

2、要获取树形节点的数据

LeftNav.vue

<template>
  <el-menu 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="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->
    <div class="logobox">
      <img class="logoimg" src="../assets/img/logo.png" alt="">
    </div>
    <el-submenu index="1-4">
      <template slot="title">
        <i class="el-icon-location"></i>
        <span>一级菜单</span>
      </template>
      <el-menu-item index="1-4-1">
        <i class="el-icon-location"></i>
        <span>二级菜单</span>
      </el-menu-item>
    </el-submenu>
  </el-menu>
</template>
<script>
  export default {
    data() {
      return {
        collapsed: false
      }
    },
    created() {
      //从总线上取出 this.collapsed 变量
      this.$root.Bus.$on("collapsed-side", v => {
        this.collapsed = v;
      });

      //获取树形节点的数据
      let url = this.axios.urls.SYSTEM_MENU_TREE;

      //this.指的是vue实例
      this.axios.post(url,{})
      .then(resp => {//代表成功  箭头函数 jdk8 的lambda
        console.log(resp);

        }).catch(function(){//代表失败

        });
    }
  }
</script>
<style>
  .el-menu-vertical-demo:not(.el-menu--collapse) {
    width: 240px;
    min-height: 400px;
  }

  .el-menu-vertical-demo:not(.el-menu--collapse) {
    border: none;
    text-align: left;
  }

  .el-menu-item-group__title {
    padding: 0px;
  }

  .el-menu-bg {
    background-color: #1f2d3d !important;
  }

  .el-menu {
    border: none;
  }

  .logobox {
    height: 40px;
    line-height: 40px;
    color: #9d9d9d;
    font-size: 20px;
    text-align: center;
    padding: 20px 0px;
  }

  .logoimg {
    height: 40px;
  }
</style>

获取数据

<script>
  export default {
    data() {
      return {
        collapsed: false
      }
    },
    created() {
      //从总线上取出 this.collapsed 变量
      this.$root.Bus.$on("collapsed-side", v => {
        this.collapsed = v;
      });

      //获取树形节点的数据
      let url = this.axios.urls.SYSTEM_MENU_TREE;

      //this.指的是vue实例
      this.axios.post(url,{})
      .then(resp => {//代表成功  箭头函数 jdk8 的lambda
        console.log(resp);

        }).catch(function(){//代表失败

        });
    }
  }
</script>

3、通过拿到的数据，渲染树形节点

<template>
  <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 v-for="m in menus" :index="'id_'+m.treeNodeId">
      <template slot="title">
        <i :class="m.icon"></i>
        <span>{{m.treeNodeName}}</span>
      </template>
      <el-menu-item  v-for="m2 in m.children" :key="'id_'+m2.treeNodeId" :index="m2.url">
        <i :class="m2.icon"></i>
        <span>{{m2.treeNodeName}}</span>
      </el-menu-item>
    </el-submenu>
  </el-menu>
</template>

4、创建文章管理

Articles.vue

<template>
  <div>
    文章管理组件
  </div>
</template>
 
<script>
  export default {
    name:'Articles',
    data() {
      return {
        asideClass: 'main-aside'
      }
    }
  };
</script>
 
<style>
</style>

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from "@/components/HelloWorld";
import AppMain from "@/components/AppMain";
import LeftNav from "@/components/LeftNav";
import TopNav from "@/components/TopNav";
import Login from "@/views/Login";
import Reg from "@/views/Reg";
import Articles from "@/views/sys/Articles";

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'Login',
      component: Login
    },
    {
      path: '/Login',
      name: 'Login',
      component: Login
    },
    {
      path: '/Reg',
      name: 'Reg',
      component: Reg
    },
    {
      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
        }
      ]
    }
  ]
})

二、右侧文章的分页查询功能

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 style="width: 100%;">
    <el-table-column align="center" type="selection" min-width="60">
    </el-table-column>
    <el-table-column sortable prop="id" label="文章ID" min-width="300">
    </el-table-column>
    <el-table-column sortable prop="title" label="文章标题" min-width="300">
    </el-table-column>
    <el-table-column sortable prop="body" label="文章内容" min-width="300">
    </el-table-column>
    <el-table-column align="center" label="操作" min-width="300">
      <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,
        total:10,
        title:''
      }
    }
  },
  methods:{
    handleSizeChange(rows) {
      this.formInline.page = 1;
      this.formInline.rows = rows;
      this.search();
    },
    handleCurrentChange(page) {
      this.formInline.page = page;
      this.search();
    },
    //是为了代码复用
    doSearch(param){
      // 获取树形节点的数据
      let url = this.axios.urls.SYSTEM_ARTICLE_LIST;

      //this指的是vue实例
      this.axios.post(url,param)
        .then(resp => {//代表成功 箭头函数 jdk8的语法
          console.log(resp);
          this.listData=resp.data.result;
          this.formInline=resp.data.pageBean;
        }).catch(function (){//代表失败

      });
    },
    search(){
    //  按照条件进行查询
      this.doSearch(this.formInline);
    }

  },
  created() {
      this.doSearch({});
  }
}
</script>
