這篇文章主要介紹了Vue實(shí)現(xiàn)Tab標(biāo)簽路由效果，并用Animate.css做轉(zhuǎn)場動(dòng)畫效果，本文通過實(shí)例代碼給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

// 設(shè)置pageList，這里清除其他，也就是保留自己 this.activePage = page.fullPath this.$router.push(this.activePage).catch(e => e) }

緩存控制

這部分邏輯比較簡單，結(jié)合注釋可以看懂

methods: {
 clearCache (route) {
 const componentName = last(route.matched).components.default.name // last方法來自lodash，獲取數(shù)組最后一個(gè)元素
 this.dustbin.push(componentName) // 清除
 },
 putCache (route) {
 const componentName = last(route.matched).components.default.name
 if (this.dustbin.includes(componentName)) {
  this.dustbin = this.dustbin.filter(item => item !== componentName) // 從dustbin中刪除當(dāng)前組件名，恢復(fù)其緩存機(jī)制
 }
 }
}

這樣，主要邏輯就做完了，下面簡單說說轉(zhuǎn)場動(dòng)畫的實(shí)現(xiàn)

轉(zhuǎn)場動(dòng)畫實(shí)現(xiàn)

轉(zhuǎn)場動(dòng)畫主要是用到 Animate.css 配合Vue的 transition 組件實(shí)現(xiàn)，組件完整代碼如下，極其簡單：

<template>
 <transition :enter-active-class="`animate__animated animate__${name}`">
 <slot />
 </transition>
</template>

<script>
export default {
 name: 'PageToggleTransition',
 props: {
 name: String
 }
}
</script>

具體參考官方文檔關(guān)于transition組件的說明

最后借鑒自 vue-antd-admin github.com/1446445040/…
