JSP基本语法集锦

1.servlet跳转到相应jsp页面

request.setAttribute("param_id", user.getUserID());    //传到参数
request.setAttribute("param_user",user.getUserName()); 
request.setAttribute("param_pwd",user.getPassword());
request.getRequestDispatcher("/mainPage.jsp").forward(request, response); //页面跳转

 

2.当文本框内容改变,并且将焦点移开,如鼠标点击其他位置,f( )会被执行

<form name="form1" method="post" action="regist.jsp">
<input type="text" name="cloze" onchange="f()" />

</form>
