标题: CGI, 如何删除表
我有如下的几行代码，当我点击"submit" 时，我希望页面只显示 “YourChoice is : JobOrder”，清除 print_form()中的内容。在此先谢谢各位高手。

#!/usr/bin/perl
use DBI;
use DBD::mysql;
use CGI qw(:standard);
$query = new CGI;
print $query->header;
print $query->start_html("Welcome to JobOrder");
&print_form($query);
my $choice = $query->param('YourChoice');
print "<tr>YourChoice is : $choice</tr>";

sub print_form{
my($query) = @_;
print $query->startform;
print "<H3>Welcome to Job dashboard</H3>";
print "Please pick your choice.<BR>";
print $query->radio_group(-name=>'YourChoice',
                        -values=>[ 'JobOrder', 'Exit' ],
                        -default=>[ 'Exit'],
                        );
print "<BR>";
print $query->submit('action', 'submit');
print $query->reset('Clear');
print $query->endform;
}
