SPA项目开发之动态树+数据表格+分页

今天让我们使用SPA开发动态树+数据表格+分页

1.后台数据
t_vue_user
t_vue_tree_node
t_vue_articles
2.动态生成NavMenu导航菜单(只支持2级菜单)
2.1 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="">

2.2 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">
        <el-menu-item index="/company/userManager">用户管理</el-menu-item>

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",注意是绑定属性，不要忘了加“:”,当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

2.3 数据表格

<el-table :data="result" style="width: 100%;" :border="true" max-height="550">
      <el-table-column prop="id" label="ID"  min-width="10" align="center"></el-table-column>
      <el-table-column prop="title" label="标题" min-width="20"></el-table-column>
      <el-table-column prop="body" label="内容" min-width="70"></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>

handleSizeChange(rows) {
				this.formInline.page = 1;
				this.formInline.rows = rows;
				this.search();
			},
			handleCurrentChange(page) {
				this.formInline.page = page;
				this.search();
			}

代码如下：

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-form-item>
		</el-form>
		<!--列表-->
		<el-table size="small" :data="listData" border element-loading-text="拼命加载中" style="width: 100%;">
			</el-table-column>
			<el-table-column sortable prop="id" label="ID" width="300">
			</el-table-column>
			<el-table-column sortable prop="title" label="文章标题" width="300">
			</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="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="formInline.rows" layout="total, sizes, prev, pager, next, jumper"
		 :total="total">
		</el-pagination>
	</div>
</template>

<script>
	export default {
		data() {
			return {
				listData: [],
				formInline: {
					title: '',
					total:0,
					page:1,
					rows:10,
					total:0
				}
			};
		},
		methods: {
			search() {
				this.doSearch(this.formInline);
			},
			doSearch(params) {
				let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
				this.axios.post(url, params).then((response) => {
					console.log(response);
					this.listData = response.data.result;
					this.total = response.data.pageBean.total;
				}).catch((response) => {
					console.log(response);
				});
			},
			handleSizeChange(rows) {
				this.formInline.page = 1;
				this.formInline.rows = rows;
				this.search();
			},
			handleCurrentChange(page) {
				this.formInline.page = page;

			}
		},
		created() {
			this.doSearch({});
		}
	}
