基于Vuejs框架實(shí)現(xiàn)翻頁組件

更新時(shí)間：2020年06月29日 09:44:53 作者：lemon678

這篇文章主要為大家詳細(xì)介紹了基于VueJs框架的翻頁組件，小巧精致，性能優(yōu)異的MVVM框架實(shí)現(xiàn)翻頁組件，也適用于angular，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

翻頁功能對前端后端都是個(gè)難題??！今天終于給踩了！哈哈！整理下方法，我是基于vueJs寫的，同樣適用于angular哈！

效果截圖：

整體實(shí)現(xiàn)邏輯，當(dāng)用戶點(diǎn)擊頁碼時(shí)，ajax從后端獲取數(shù)據(jù)，包括：records（當(dāng)前頁查詢到的記錄），totalRecords: 121（所有記錄），currentPage（當(dāng)前頁碼），totalPage（總頁碼），size（當(dāng)前頁顯示數(shù)量），之后用我封裝的算法assemblePageTurnerParams，算出頁面展示哪些頁碼。

不得不說，我考慮的很全面的哈！！頁碼多的時(shí)候顯示省略號，頁碼少的時(shí)候，則顯示的少！

源碼如下：
