要将“展开”和“收起”功能替换为点击图标(<el-icon><Fold /></el-icon>
和 <el-icon><Expand /></el-icon>
),您需要对现有的代码进行一些小的修改。具体步骤如下:
- 导入所需的图标组件。
- 将原有的
<el-radio-group>
部分替换为包含图标的按钮,并添加事件处理函数。
下面是更新后的代码示例:
<template>
<el-container style="height: 500px; border: 1px solid #eee">
<el-menu default-active="1-4-1" class="el-menu-vertical-demo" @open="handleOpen" @close="handleClose"
:collapse="isCollapse">
<el-submenu index="1">
<template slot="title">
<i class="el-icon-location"></i>
<span slot="title">导航一</span>
</template>
<el-menu-item-group>
<span slot="title">分组一</span>
<el-menu-item index="1-1">选项1</el-menu-item>
<el-menu-item index="1-2">选项2</el-menu-item>
</el-menu-item-group>
<el-menu-item-group title="分组2">
<el-menu-item index="1-3">选项3</el-menu-item>
</el-menu-item-group>
<el-submenu index="1-4">
<span slot="title">选项4</span>
<el-menu-item index="1-4-1">选项1</el-menu-item>
</el-submenu>
</el-submenu>
<el-menu-item index="2">
<i class="el-icon-menu"></i>
<span slot="title">导航二</span>
</el-menu-item>
<el-menu-item index="3" disabled>
<i class=" el-icon-document"></i>
<span slot="title">导航三</span>
</el-menu-item>
<el-menu-item index="4">
<i class=" el-icon-setting"></i>
<span slot="title">导航四</span></li>
</elmenuitem >
</elm menu >
<!-- 控制图标 -->
<!-- 改成点击图标来实现展开和收起 -->
<
el container >
<
el header style = "text-align: right; font-size: 12px" >
<
span style = "float: left; margin-top: 10px; cursor: pointer;" @click = "change" >
<
el - icon v-if = "!isCollapse" > <
Fold / > <
/ el - icon > <
el - icon v-if = "isCollapse" > <
Expand / > <
/ el - icon >
</ span >
<!-- 下拉菜单和用户名显示 -->
...
<
/ el header >
<
el main >
...
<
/ el main >
</
el container >
</
el container >
</>
);
<style scoped>
.el menu vertical demo:not(.El menu--collapse) {
width: 200px;
min-height: 400px;
}
.el header {
background-color: #B3C0D1;
color: #333;
line-height: 60px;
}
.el aside {
color: #333;
}
</style>
<script>
export default {
name: 'layoutPage',
data() {
const item = { date:'2016-05-02', name:'王小虎', address:'上海市普陀区金沙江路1518弄' };
return { tableData:Array(20).fill(item), isCollapse:true } } ,
methods:{ change() { this.isCollapse=!this.isCollapse }, handleOpen(key,keyPath){ console.log(key,keyPath); }, handleClose(key,keyPath){ console.log(key,keyPath); }}
};
</script>
在这个示例中,已将<ul radio group>
替换为使用图标(折叠和展开)来切换侧边栏的状态。点击这些图标会调用 change()
方法,切换 isCollapse
的值,从而实现展开和收起功能。
