端口号不是问题。 否则,你将在Tomcat的启动日志中得到一个exception,并且浏览器将显示一个特定于浏览器的“连接超时”错误页面(因此,当Tomcat未启动并运行时,不会出现Tomcat特定的错误页面。

getElementById() 用来获取表上的控件ID。如果存在返回 ID,不存在返回undefind

if(isSame("txt_user_pass").value,"txt_user_pass_confirm").value),这句话可能有问题,大括号缺少一个,自己仔细检查下。

<form action="" onsubmit="return check_submit()">form代表表单,action我也不晓得是干毛的。onsubmit代表提交整个表单时触发某一个事件,存储过程。运行没反应参见上面那句IF判断。

input默认的控件就是 text类型,可以省略不写。其他类型,如BUTTON,RADIO,SELECT就必须写上TYPE=‘BUTTON’。

id='txt_user_name' 是控件的ID,在FORM表单里表是唯一存在的。不信你多写几个试试,肯定报错。规则的命名方法是 控件类型缩写+英文识别单词。txt代表文本框控件,user_name代表这个文本框是用来显示或者存储用户姓名的。
