Vue3+Element Plus实现动态标签页以及右键菜单功能
作者：日进斗识
这篇文章主要给大家介绍了关于Vue3+Element Plus实现动态标签页以及右键菜单功能的相关资料,Vue 3和Element Plus提供了一种简单的方法来实现侧边菜单栏与标签页之间的联动,文中通过代码介绍的非常详细,需要的朋友可以参考下
先上图
只有首页的情况
多个tab页的情况
使用el-dropdown绑定右键菜单，为每个tab页绑定一个右键
<el-tabs v-model="activeTab" @tab-click="clickTab" type="border-card" class="demo-tabs" closable @edit="removeTab">
<el-tab-pane v-for="(item, index) in tabs" :key="item.path" :label="item.name" :name="item.path">
<template #label>
<el-dropdown :trigger="['contextmenu']" ref="dropdownRef" :id="item.name"
@visible-change="handleChange($event, item.name)">
{{ item.name }}
<template #dropdown>
<el-dropdown-menu>
<el-dropdown-item @click="reload(item)" :disabled="handDisabled('reload', item, index)">
<el-icon>
<Refresh />
</el-icon>重新刷新
</el-dropdown-item>
<el-dropdown-item v-if="item.path != '/welcome'" @click="closeMy(item)"
:disabled="handDisabled('closeMy', item, index)">
<el-icon>
<Close />
</el-icon>关闭当前</el-dropdown-item>
<el-dropdown-item v-if="tabs.length > 1" @click="closeOther(item)"
:disabled="handDisabled('closeOther', item, index)">
<el-icon>
<Remove />
</el-icon>关闭其他</el-dropdown-item>
<el-dropdown-item v-if="tabs.length > 1" @click="closeAll(item)"
:disabled="handDisabled('closeAll', item, index)">
<el-icon>
<Minus />
</el-icon>关闭全部</el-dropdown-item>
</el-dropdown-menu>
</template>
</el-dropdown>
</template>
</el-tab-pane>
<!--路由占位符-->
<router-view></router-view>
</el-tabs>右键菜单生效后控制每个下拉项的禁用与显示(每一项代表一个功能)
const handDisabled = (action: string, data: any, index: any) => {
if (action == 'reload') {
return route.path != data.path
}
if (action == 'closeMy') {
return route.path != data.path
}
if (action == 'closeOther') {
return route.path != data.path
}
return false
}每个右键项对应的功能
const reload = (item: any) => {
router.go(0)
}
const closeMy = (item: any) => {
removeTab(item.path)
}
const closeOther = (item: any) => {
const welcome = { name: "欢迎界面", path: "/welcome" }
console.info(item)
tabsSt.setTabs([welcome])
const { name, path } = item
let oldTabs: any = []
tabs.value.forEach((element: any) => {
oldTabs.push(element.path)
});
if (!oldTabs.includes(path)) {
tabs.value.push({ name: name as any, path })
}
}
const closeAll = (item: any) => {
const welcome = { name: "欢迎界面", path: "/welcome", }
tabsSt.setTabs([welcome])
router.push('/welcome')
}控制每次只显示一个右键
const dropdownRef = ref()
const handleChange = (visible: boolean, name: string) => {
if (!visible) return
dropdownRef.value.forEach((item: { id: string; handleClose: () => void }) => {
if (item.id === name) return
item.handleClose()
})
}完整代码
