SPA项目开发之动态树+数据表格+分页

**动态生成NavMenu导航菜单(只支持2级菜单)**  
**1 结构 ：**

<el-menu key="" index="">
    <el-submenu>
    <template slot="title">
    <i class="el-icon-location"></i>
    <span>导航一</span>
    </template>
    <template slot="title">分组一</template>
    <el-menu-item route="">

**2 vue+element的el-menu组件实现路由跳转及当前项的设置**

<el-menu router :default-active="$route.path">

注1：要实现路由跳转，先要在el-menu标签上添加router属性，然后只要在每个el-menu-item标签内  
 的index属性设置一下url即可实现点击el-menu-item实现路由跳转。  
 注2：导航当前项，在el-menu标签中绑定 :default-active="$route.path",注意是绑定属性，  
 不要忘了加“:”,当$route.path等于el-menu-item标签中的index属性值时则该item为当前项。

注3：后台t\_tree\_node表有几个节点的url为空，则会导致几个节点样式会一致

**(动态树)leftNav.vue:**

<template>
      <el-menu router :default-active="$route.path"  class="el-menu-vertical-demo" background-color="#334157" text-color="#fff"
        active-text-color="#ffd04b" :collapse="collapsed">
        
        <div class="logobox">
          <img class="logoimg" src="../assets/img/logo.png" alt="">
        </div>
        
        <el-submenu :index="'id_'+m.treeNodeId" v-for="m in menus">
          <template slot="title">
            <i :class="m.icon"></i>
            <span>{
         {m.treeNodeName}}</span>
          </template>
          <el-menu-item :key="'id_'+m2.treeNodeId" :index="m2.url" v-for="m2 in m.children"> <template slot="title">
            <i :class="m2.icon"></i>
            <span>{
         {m2.treeNodeName}}</span>
          </template></el-menu-item>
        </el-submenu>
      </el-menu>

        },
        created() {
          this.$root.Bus.$on("collaspsed-side", (v) => {
            this.collapsed = v;
          });
          let url = this.axios.urls.SYSTEM_MENU_TREE;
          this.axios.post(url,{}).then((response) => {
            console.log(response);
            this.menus=response.data.result
          }).catch((response) => {
            console.log(response);
    
          });
        }
      }
    </script>
    <style>
      .el-menu-vertical-demo:not(.el-menu--collapse) {

      }
    
      .el-menu-vertical-demo:not(.el-menu--collapse) {

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

**数据表格：**

**结构：**

<el-table :data="listData" stripe style="width: 100%">
          <el-table-column prop="id" label="ID" width="430">
          </el-table-column>
          <el-table-column prop="title" label="文章标题" width="430">
          </el-table-column>
          <el-table-column prop="body" label="文章内容" width="430">
          </el-table-column>
        </el-table>

**分页：**

<el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
    		:current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="formInline.rows" layout="total, sizes, prev, pager, next, jumper"
    		:total="pageBean.total">
    		</el-pagination>

**　分页js:**

handleSizeChange(rows) {
            console.log('页码大小发生改变'+rows);
    				this.formInline.page = 1;
    				this.formInline.rows = rows;
    				this.search();
    			},
    			handleCurrentChange(page) {
            console.log('当前页码发生改变'+page);
    				this.formInline.page = page;
    				this.search();
    			}

**　数据表格+分页Articles.vue组件：**

<template>

          <el-form-item label="搜索:">
