這篇文章主要給大家介紹了關(guān)于Vue3+Element?Plus實(shí)現(xiàn)動(dòng)態(tài)標(biāo)簽頁(yè)以及右鍵菜單功能的相關(guān)資料,Vue?3和Element?Plus提供了一種簡(jiǎn)單的方法來(lái)實(shí)現(xiàn)側(cè)邊菜單欄與標(biāo)簽頁(yè)之間的聯(lián)動(dòng),文中通過(guò)代碼介紹的非常詳細(xì),需要的朋友可以參考下

先上圖
使用el-dropdown綁定右鍵菜單，為每個(gè)tab頁(yè)綁定一個(gè)右鍵
右鍵菜單生效后控制每個(gè)下拉項(xiàng)的禁用與顯示(每一項(xiàng)代表一個(gè)功能)
每個(gè)右鍵項(xiàng)對(duì)應(yīng)的功能
控制每次只顯示一個(gè)右鍵

只有首頁(yè)的情況

多個(gè)tab頁(yè)的情況

使用el-dropdown綁定右鍵菜單，為每個(gè)tab頁(yè)綁定一個(gè)右鍵

<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>關(guān)閉當(dāng)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>關(guān)閉其他</el-dropdown-item>
                            <el-dropdown-item v-if="tabs.length > 1" @click="closeAll(item)"
                                :disabled="handDisabled('closeAll', item, index)">
                                <el-icon>
                                    <Minus />
                                </el-icon>關(guān)閉全部</el-dropdown-item>
                        </el-dropdown-menu>
                    </template>
                </el-dropdown>
            </template>
        </el-tab-pane>
        <!--路由占位符-->
        <router-view></router-view>
    </el-tabs>

右鍵菜單生效后控制每個(gè)下拉項(xiàng)的禁用與顯示(每一項(xiàng)代表一個(gè)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
}

每個(gè)右鍵項(xiàng)對(duì)應(yīng)的功能

const reload = (item: any) => {
    router.go(0)
}
const closeMy = (item: any) => {
    removeTab(item.path)
}
const closeOther = (item: any) => {
    const welcome = { name: "歡迎界面", 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: "歡迎界面", path: "/welcome", }
    tabsSt.setTabs([welcome])
    router.push('/welcome')
}

控制每次只顯示一個(gè)右鍵

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()
    })
}
