vue2.0在table中實(shí)現(xiàn)全選和反選的示例代碼

更新時(shí)間：2017年11月04日 09:07:47 作者：愛喝酸奶的吃貨

這篇文章主要介紹了vue2.0在table中實(shí)現(xiàn)全選和反選的示例代碼，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

其實(shí)在去年小穎已經(jīng)寫過一篇：Vue.js實(shí)現(xiàn)checkbox的全選和反選

小穎今天在跟著慕課網(wǎng)學(xué)習(xí)vue的過程中，順便試試如何在table中實(shí)現(xiàn)全選和反選，頁面的css樣式是直接參考慕課網(wǎng)的樣式寫的，js是小穎自己寫噠，歡迎大家吐槽和點(diǎn)贊，嘻嘻

demo的 git 地址：ShoppingCart

頁面效果：

具體怎么實(shí)現(xiàn)的呢？

使用localstorage來存儲頁面信息中已經(jīng)有寫項(xiàng)目是怎么創(chuàng)建的所以小穎在這里就不重復(fù)了，其實(shí)只是在上篇文章的基礎(chǔ)上稍微做了改動：
