Hello Rancehers,
I am doing jsp registration form , in that form I have many fields like, fanme, lname, city, state, when I submit the jsp page with HTTP post method
and the saveregister.jps page I check like the request parameter
I know javascript we can validate the jsp page and then we can allow to post the page. But I wanted to know, if I submit the page, whether any way we can check the request.getparameter('field')==null
if(request.getparameter("city")==null)
out.println("city is not filled");
Please give me some suggestions
regards
