Hi All
I am trying to use javascript in my perlCGI version. I would like to bring up a popup box, to check the value entered in one of the textfield when the user clicks the submit button. I have given what I have done so far. What I need to do is either refresh the page/return to the same page when the user clicks cancel in the popupbox and continue with the process when said OK. 
sub write_form{

   my $additional_html = shift;
    
    $additional_html ||='';
    print $dw->header({'menu'   => 1,
                   'script' => "function check_name() {  
                             var sname;
                 var r;
                             sname = document.main.snp.value;
                             confirm(sname) ;  
                       }" });
   

               
    print $additional_html;
    print $cgi->br();
    print $cgi->h4('Register TaqMan Assay');
    print $cgi->br();
    print $cgi->start_form({-name =>'main',
                    -method =>'post',
                -action =>'/cgi-bin/prodsoft/Genotyping/register_taqma
+n_new.pl',
                -onSubmit=>'return check_name()'});


}

Could you drop in any suggestions on i) how could we check the cancel clicked and return the same page or refresh the page? ii) instead of checking when 'clicking the submit' is there any other way to check them before ?
thanks
