SPA项目开发之动态树+数据表格+分页

作者:互联网

一、动态树

1.数据库表

左侧树形菜单数据 

2.在create方法中通过Ajax进行数据读取

 let url = this.axios.urls.SYSTEM_MENU_TREE;
      this.axios.post(url, {}).then((resp) => {
        console.log(resp);
        this.menus=resp.data.result
      }).catch(function(error) {
        console.log(error);
      });

3.遍历menus数组,将数据渲染到页面中

<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="'id_'+i.treeNodeId" v-for="i in menus">
      <template slot="title">
        <i :class="i.icon"></i>
        <span>{{i.treeNodeName}}</span>
      </template>
      <el-menu-item :key="'id_'+i2.treeNodeId" :index="i2.url" v-for="i2 in i.children">
        <i :class="i2.icon"></i>
        <span>{{i2.treeNodeName}}</span>
      </el-menu-item>
    </el-submenu>
  </el-menu>
</template>

 index为跳转路径  key相当于标识列,唯一

4.页面展示

5.定义跳转控件

 5.1 引入element代码

5.2 定义锚点

 

5.3 根据数据库构造页面位置 

在view目录下建立sys目录,然后建立Articles控件

 

5.4 Articles代码

 

5.5 点击文件管理时右边跳转Articles界面

二、数据表格

1.表格框架

<template>
  <el-table size="small" :data="result" border element-loading-text="拼命加载中" style="width: 100%;">
    <el-table-column align="center" type="selection" min-width="1">
    </el-table-column>
    <el-table-column sortable prop="id" label="文章id" min-width="1">
    </el-table-column>
    <el-table-column sortable prop="title" label="文章标题" min-width="3">
    </el-table-column>
    <el-table-column sortable prop="body" label="文章内容" min-width="5">
    </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>

</template>

2.数据读取

  export default {
    name: 'Articles',
    data() {
      return {
        result: [],


      }
    },
    created() {
      let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
      this.axios.post(url, this.ruleForm).then((resp) => {
        console.log(resp);
        this.result = resp.data.result;
      }).catch(function(error) {
        console.log(error);
      });
    }
  }

三、分页和查询

1.从element官网中找到分页组件复制到表格下面

 <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>

 2.定义组件中的数据和方法

  export default {
    name: 'Articles',
    data() {
      return {
        result: [],
        formInline: {
          page: 1,
          total: 0,
          rows: 12,
        }
      }
    },
    methods: {
      handleSizeChange(rows) {
        console.log(rows)
        this.formInline.page = 1;
        this.formInline.rows = rows;
        this.search();
      },
      handleCurrentChange(page) {
        console.log(page)
        this.formInline.page = page;
        this.search();
      }
    },
    created() {
      let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
      this.axios.post(url, this.ruleForm).then((resp) => {
        console.log(resp);
        this.result = resp.data.result;
        this.formInline.total=resp.data.pageBean.total;
      }).catch(function(error) {
        console.log(error);
      });
    }
  }

修改total值

 this.formInline.total=resp.data.pageBean.total;

 

handleSizeChange方法表示 每页多少条数据

handleCurrentChange 方法表示当前 第几页

3.效果展示

目录

一、动态树

二、数据表格

三、分页和查询


 <el-form :inline="true" :model="formInline" class="user-search">
      <el-form-item label="搜索:">
        <el-input size="small" v-model="formInline.title" placeholder="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>

5.定义doSearch方法

doSearch(param){
        let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
        this.axios.post(url, param).then((resp) => {
          console.log(resp);
          this.result = resp.data.result;
          this.formInline.total=resp.data.pageBean.total;
        }).catch(function(error) {
          console.log(error);
        });
        this.$root.Bus.$on("zd", (v) => {
          this.collapsed = v
        })
      },

为了方便的处理传参和不传参问题,将create中的代码挪到doSearch中,成为公共方法

让create调用doSearch方法,这里不需要传参

created() {
      this.doSearch({})

    }

6.定义search方法,这里需要将关键字传进来进行查询

 search(){
        this.doSearch(this.formInline)
      }

7.最终效果展示
