當初我覺得一個網(wǎng)站上注冊和登錄這兩個功能很神奇,后來自己研究一下發(fā)現(xiàn)其實道理很簡單,接下來看一下怎么實現(xiàn)的吧。。。。
我在我的電腦上建了幾個文件:
login.html (登錄頁面)
register.html(注冊頁面)
success.html(登錄成功跳轉頁面)
return.html(注冊成功頁面)
login.php
register.php
登錄界面和注冊界面以及success.html并沒有
什么都是些html標記如下:

return.html是注冊成功之后呈現(xiàn)的頁面,里面有一段js代碼是用來定時返回登錄界面的

register.php這是與注冊頁面相對應后臺頁面
