JSP基本语法集锦

1.servlet跳转到相应jsp页面

代码

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>
