關於tag標籤元件
阿新 • • 發佈：2022-04-18
在專案中遇到這麼一個需求，點選側邊欄時會彈出標籤，點選頁面的表格時也會彈出標籤，在網上找的資料只有在側邊欄點選的時候彈標籤，沒有表格內的內容點選時彈標籤，所以自己將tag元件改了一下，還好，完美適合需求
在網上百度的tagView多頁籤的程式碼

import TagsView from './TagsView'
Vue.component('TagsView', TagsView)
並在store中引入該模組
import tagsView from './modules/tagsView' const store = new Vuex.Store({ modules: { app, settings, user, permission, tagsView }, getters })
<template>
<div :class="classObj" class="app-wrapper">
<div v-if="device==='mobile'&&sidebar.opened" class="drawer-bg" @click="handleClickOutside" />
<sidebar class="sidebar-container" />
<div class="main-container">
<div :class="{'fixed-header':fixedHeader}">
<navbar />
<!-- 放置tabsview -->
<tags-view />
</div>
<app-main />
</div>
</div>
</template>
將以上程式碼複製到自己的專案中然後根據自己的需要相對應的更改（以上程式碼只能實現側邊欄點選增加tag標籤）
我的專案需求中因為牽扯到側邊欄點選新增tag標籤和側邊欄點擊出來的表格中點選表格項也要新增相應的標籤，所以對上面的程式碼進行修改
主要的思路是根據fullPath進行判斷，因為每個頁面的path可能一樣，但是fullPath一定不同
