JSP Learning Notes (iv)-----The use of JSP actions

js| notes

1. This example mainly tells us how to use JSP actions in JSP code, such as <jsp:forward >
2. This example requires four documents: login.jsp,test.jsp,ok.htm,no.htm
3. First look at the login.jsp
＜html＞
＜center＞
＜form method=get action="http://127.0.0.1:8000/test.jsp"＞
username＜input type=text name=username＞
＜br＞＜br＞
password＜input type=password name=password＞
＜br＞＜br＞
＜input type=submit value="确定"＞
＜/form＞
＜/center＞
＜/html＞
4. The test.jsp code is as follows:
＜html＞
＜%
String username=request.getParameter("username");
if(username.trim().equals("abc"))
{%＞
＜jsp:forward page="ok.html" /＞
＜%}
else
{%＞
＜jsp:forward page="no.html" /＞
＜%}
%＞
＜/html＞
5. Ok.htm and no.htm are very simple, casually written:

＜html＞ok＜/html＞
＜html＞no＜/html＞


6. The final configuration, very simple:

Put login.jsp,test.jsp,ok.htm,no.htm in the public_html of Java EE, you do not need to start the Java-ee deployer, this is a simple way

7. The effect is when you enter the user name is ABC, the page will automatically jump to the ok.htm page, otherwise jump to the no.htm page
