Need Help on Jsp

Question

I am trying to figure out a bunch of code in jsp, it is a html form with some textfield and two button, one is "ok" and another is "cancel", I want to make different response when client click on the buttons, if they choose ok, I want to insert the value of those text field into an arrylist, and return back to previous jsp page, if they choose cancel, I just want to return back to previous jsp page, and with nothing changed in the arrylist, I was wondering how can I deal with the button name with both method "submit" and action"./some.jsp".
Please help! thx a lot!

Answer 1

I would handle it by using a Back() function in javascript at the top of your html page. It is triggered only when the cancel button is onclicked.
<SCRIPT LANGUAGE="JavaScript">
     <!-- Begin
     function Back(myform)
          window.location.href= "some.jsp";
     </SCRIPT>
<FORM NAME=MYFORM ACTION=/SOME.JSP>
..here's all your input text fields
<INPUT type=text etc.. etc...
<INPUT type=submit value='OK'>
<INPUT type=submit ONCLICK = Back(this)value='CANCEL'>
</FORM>
I hope this helps.
