一、页面样式
使用jQuery实现登录与注册页面滑动显示,登录与修改密码页面淡入淡出显示,简单的表单验证,注册数据采用localStorage本地储存。
二、实现功能
-
jQuery实现页面切换滑动动画
-
三大模块:登录模块、注册模块、修改密码模块
登录:
注册:
修改密码:
-
注册模块用户username与password采用localStorage本地浏览器储存
4.基本的表单输入用户名密码的格式与字符串类型、字符个数验证,采用正则表达式来验证
javascript"> // 数字与字母的正则表达式
let zg = /^[0-9a-zA-Z]*$/;
// 汉字正则表达式
let reg = /^[^\u4e00-\u9fa5]+$/;
三、不足之处
- js代码有点杂乱,不过相应的注释都有,对应的模块都有,只是需要封装一下重复代码。
