超市會員管理系統要求
·系統菜單分爲兩級
一級菜單：登陸、開卡、退出系統
二級菜單(登陸以後)：積分累積、積分兌換、積分查詢、修改密碼、退出登陸dom
·開卡的帳號不能重複ui
·驗證用戶名
用戶名不能以數字開頭，不能有特殊符號，用戶名長度必須是3-6位之間
·驗證密碼
密碼長度必須是6-16位之間，不能有中文、空格，驗證密碼強度：
純數字、純英文是低，數字+英文是中，數字+英文+特殊字符是高
·開卡時須要輸入驗證碼，驗證碼不區分大小寫this
·輸入積分、消費金額時，必須是數字，若不是數字從新輸入spa
·修改密碼若是是舊密碼則提示修改失敗，若是是新密碼也要驗證密碼，而且修改爲功後須要退出從新登陸code
·登陸時，若是密碼連續輸入五次失敗，則凍結當前帳戶blog
·登陸時，有忘記密碼提示，因此要求要實現密保問題驗證，在忘記密碼時可以找回密碼get
