本篇內(nèi)容介紹了“原生JavaScript怎么實(shí)現(xiàn)模態(tài)框”的有關(guān)知識(shí),在實(shí)際案例的操作過程中,不少人都會(huì)遇到這樣的困境,接下來就讓小編帶領(lǐng)大家學(xué)習(xí)一下如何處理這些情況吧!希望大家仔細(xì)閱讀,能夠?qū)W有所成!
最近需要一個(gè)模態(tài)框,然后一種是提示類的,一種是確認(rèn)類型,我就想著再網(wǎng)上找一個(gè)然后修改一下,結(jié)果找到了,但是不深特別合適,我再次基礎(chǔ)上在做了修改,對(duì)功能有所增強(qiáng),純?cè)鷮懙?,沒有任何依賴性,適應(yīng)性比較強(qiáng),值copy即可使用。
配置:可以在實(shí)例化時(shí)對(duì)options進(jìn)行參數(shù)設(shè)置,達(dá)到自己想要的效果
