使用vue怎么實(shí)現(xiàn)一個(gè)視頻上傳功能

本篇文章為大家展示了使用vue怎么實(shí)現(xiàn)一個(gè)視頻上傳功能，內(nèi)容簡(jiǎn)明扼要并且容易理解，絕對(duì)能使你眼前一亮，通過(guò)這篇文章的詳細(xì)介紹希望你能有所收獲。

Vue的優(yōu)點(diǎn)

Vue具體輕量級(jí)框架、簡(jiǎn)單易學(xué)、雙向數(shù)據(jù)綁定、組件化、數(shù)據(jù)和結(jié)構(gòu)的分離、虛擬DOM、運(yùn)行速度快等優(yōu)勢(shì)，Vue中頁(yè)面使用的是局部刷新，不用每次跳轉(zhuǎn)頁(yè)面都要請(qǐng)求所有數(shù)據(jù)和dom，可以大大提升訪問(wèn)速度和用戶體驗(yàn)。
