這篇文章主要介紹“怎么用js和ajax實(shí)現(xiàn)加載時(shí)的進(jìn)度條”,在日常操作中,相信很多人在怎么用js和ajax實(shí)現(xiàn)加載時(shí)的進(jìn)度條問題上存在疑惑,小編查閱了各式資料,整理出簡單好用的操作方法,希望對(duì)大家解答”怎么用js和ajax實(shí)現(xiàn)加載時(shí)的進(jìn)度條”的疑惑有所幫助!接下來,請(qǐng)跟著小編一起來學(xué)習(xí)吧!

最終效果如下圖所示,pc和移動(dòng)端都可以展示的,調(diào)用方法也很簡單,開始調(diào)用:loading.baosight.showPageLoadingMsg(false),alse代表不現(xiàn)實(shí)加載說明,true展示加載說明.調(diào)用完成后調(diào)用:loading.baosight.hidePageLoadingMsg(),在整個(gè)代碼里有兩個(gè)文件,一個(gè)是js文件,一個(gè)是css文件。切記不要忘記引入jquery.js
