"if" condition based on form submit

"if" condition based on form submit

"if" condition based on form submit

(OP)
I have a function which i want to call on the submit of a form.

e.g.
<form>
some code
<input type=submit name=somename onClick=document.form.action=page2.jsp>

<% if (here i want the code that says implement "if" if the submit button is pressed). I'm trying,

if(request.getParameter(somename).equalsIgnoreCase(submit){}

but it implements the if on page load and gives a null pointer exception.

Thanks in advance for your help

RE: "if" condition based on form submit

> if(request.getParameter(somename).equalsIgnoreCase(submit){}

request.getParameter("hello")

That will return 'null' if 'somename' doesnot exist therefore you end up with

null.equalsIgnoreCase(submit)

hence the null pointer exception

Good luck

RE: "if" condition based on form submit

pete got it right::
but start your page with
<%if (null.equalsIgnoreCase(submit)){
%>
show your form

<%} else {
//handle your code

}%>
