SPA项目开发之动态树+数据表格+分页
1. 动态生成NavMenu导航菜单(只支持2级菜单)
1.1 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="$route.path">
注1：要实现路由跳转，先要在el-menu标签上添加router属性，然后只要在每个el-menu-item标签内
的index属性设置一下url即可实现点击el-menu-item实现路由跳转。
注2：导航当前项，在el-menu标签中绑定 :default-active="$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

<template> <el-menu router :default-active="$route.path" class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b" :collapse="collapsed"> <!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$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> <!-- 注意：index是必填的属性 1.index可以看成ID，也就是说它是惟一的 2.它代表着路由的跳转路径--> <el-submenu :key="'id_'+m.treeNodeId" :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> </template> <script> export default { data() { return { collapsed: false, menus: [] } }, created() { this.$root.Bus.$on("collapsed-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(function(error) { console.log(error); }); } } </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>

2.3 数据表格
<el-table size="small" :data="listData" style="width: 100%;" border max-height="550" element-loading-text="拼命加载中"> <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>
2.4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="pageBean.total"> </el-pagination>
数据表格+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-form-item>
</el-form>
<!-- 列表-->
<el-table size="small" :data="listData" style="width: 100%;" border max-height="550" element-loading-text="拼命加载中">
<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>
<!-- 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="pageBean.total">
</el-pagination>
</div>
</template>
<script>
export default {
data() {
return {
listData: [],
pageBean: {
total: 0
},
formInline: {
title: '',
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.pageBean = response.data.pageBean;
}).catch(function(error) {
console.log(error);
});
},
handleSizeChange(rows) {
console.log('页码大小发生改变的时候触发！！！' + rows)
this.formInline.page = 1;
this.formInline.rows = rows;
this.search();
},
handleCurrentChange(page) {
console.log('当前页页码发生改变的时候触发！！！' + page)
this.formInline.page = page;
this.search();
}
},
created() {
this.doSearch({});
}
}
</script>
