html中車牌號(hào)省份簡(jiǎn)稱輸入鍵盤的示例代碼

 2020-11-17 13:42  來(lái)源： 腳本之家   我來(lái)投稿 撤稿糾錯(cuò)

　 域名預(yù)訂/競(jìng)價(jià)，好“米”不錯(cuò)過(guò)

這篇文章主要介紹了html中車牌號(hào)省份簡(jiǎn)稱輸入鍵盤的示例代碼，文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

原理是先寫出一個(gè)按鍵的div,然后再根據(jù)屏幕的大小去自動(dòng)適應(yīng)生成鍵盤，效果如下圖：

具體實(shí)現(xiàn)代碼如下，就不細(xì)說(shuō)了。
