Container component used for layout, convenient for quickly building the basic structure of the page:
<el-container>: outer container . When the child elements contain <el-header> or <el-footer>, all child elements will be arranged vertically up and down, otherwise they will be arranged horizontally left and right
<el-header>：Top bar container
<el-aside>：Side bar container
< ;el-main>：Main area container
<el-footer>：Bottom column container
<body>
<div id="app">
<el-container>
<el-header>Header</el-header>
<el-container>
<el-aside width="200px">Aside</el-aside>
<el-container>
<el-main>Main</el-main>
<el-footer>Footer</el-footer>
</el-container>
</el-container>
</el-container>
</div>
<style>
.el-header, .el-footer {
background-color: #B3C0D1;
color: #333;
text-align: left;
line-height: 60px;
}
.el-aside {
background-color: #D3DCE6;

}
.el-main {
background-color: #E9EEF3;

<el-dropdown split-button size="small" trigger="click"> 个人中心 <el-dropdown-menu> <el-dropdown-item >退出系统</el-dropdown-item> <el-dropdown-item divided>修改密码</el-dropdown-item> <el-dropdown-item divided>联系管理员</el-dropdown-item> </el-dropdown-menu> </el-dropdown>
A menu that provides navigation functions for the website.
<el-menu> <el-submenu index="1"> <template slot="title"> <i class="el-icon-location"></i> <span slot="title">导航一</span> </template> <el-menu-item>选项1</el-menu-item> <el-menu-item>选项2</el-menu-item> <el-menu-item>选项3</el-menu-item> </el-submenu> <el-submenu index="2"> <template slot="title"> <i class="el-icon-menu"></i> <span slot="title">导航二</span> </template> <el-menu-item>选项1</el-menu-item> <el-menu-item>选项2</el-menu-item> <el-menu-item>选项3</el-menu-item> </el-submenu> </el-menu>
is used to display multiple pieces of data with similar structure. The data can be sorted, filtered, compared or other customized operations.
<el-table :data="tableData" stripe>
<el-table-column prop="date" label="日期"></el-table-column>
<el-table-column prop="name" label="姓名"></el-table-column>
<el-table-column prop="address" label="地址"></el-table-column>
<el-table-column label="操作" align="center">
<!--
slot-scope：作用域插槽，可以获取表格数据
scope：代表表格数据，可以通过scope.row来获取表格当前行数据，scope不是固定写法
-->
<template slot-scope="scope">
<el-button type="primary" size="mini" @click="handleUpdate(scope.row)">编辑</el-button>
<el-button type="danger" size="mini" @click="handleDelete(scope.row)">删除</el-button>
</template>
</el-table-column>
</el-table>
<script>
new Vue({
el:'#app',
data:{
tableData: [{
date: '2016-05-02',
name: '王小虎',
address: '上海市普陀区金沙江路 1518 弄'
}, {
date: '2016-05-04',
name: '王小虎',
address: '上海市普陀区金沙江路 1517 弄'
}, {
date: '2016-05-01',
name: '王小虎',
address: '上海市普陀区金沙江路 1519 弄'
}]
},
methods:{
handleUpdate(row){
alert(row.date);
},
handleDelete(row){
alert(row.date);
}
}
});
</script>When the amount of data is too large, use paging to break down the data.
<!--
current-change：内置的事件，当前页码改变时会触发，可以获取到改变之后的页码
-->
<el-pagination
@current-change="handleCurrentChange"
current-page="5"
page-size="10"
layout="total, prev, pager, next, jumper"
:total="305">
</el-pagination>
<script>
new Vue({
el:'#app',
methods:{
handleCurrentChange(page){
alert(page);
}
}
});
</script>is often used as a feedback prompt after active operations.
<el-button :plain="true" @click="open1">消息</el-button>
<el-button :plain="true" @click="open2">成功</el-button>
<el-button :plain="true" @click="open3">警告</el-button>
<el-button :plain="true" @click="open4">错误</el-button>
<script>
new Vue({
el: '#app',
methods: {
open1() {
this.$message('这是一条消息提示');
},
open2() {
this.$message({
message: '恭喜你，这是一条成功消息',
type: 'success'
});
},
open3() {
this.$message({
message: '警告哦，这是一条警告消息',
type: 'warning'
});
},
open4() {
this.$message.error('错了哦，这是一条错误消息');
}
}
})
</script>Separate data collections that are related in content but belong to different categories.
