H5页面随机数字键盘支付页面
生活随笔
收集整理的這篇文章主要介紹了
H5页面随机数字键盘支付页面
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
H5頁(yè)面隨機(jī)數(shù)字鍵盤支付頁(yè)面
有個(gè)H5支付的業(yè)務(wù)需要隨機(jī)數(shù)字的鍵盤
參考了下文：https://blog.csdn.net/Mr_Smile2014/article/details/52473351
做了一些小修改：
在原有的基礎(chǔ)上，增加了一些按鍵反饋的效果。
每個(gè)按鍵加上邊框。
最終效果：
下面是所有代碼：
1.HTML頁(yè)面+JS
