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(wèn)題上存在疑惑，小編查閱了各式資料，整理出簡(jiǎn)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(lái)，請(qǐng)跟著小編一起來(lái)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(jiǎn)單，開始調(diào)用：loading.baosight.showPageLoadingMsg(false),alse代表不現(xiàn)實(shí)加載說(shuō)明,true展示加載說(shuō)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
