In a pinch, I've put the javascript in a string (with a heredoc); printed it with the html header; and accessed it with onClick. Below is a simple example: 

use strict;
use CGI qw(:standard);

my $js = <<"EOJS";
function someChecked(form) {
  var boxes = form.getElementsByTagName("input");
  for (var i = 0; i < boxes.length; i++) {
    if (boxes[i].checked == true) return true;
  }
  alert("You didn't select any items to delete!");
  return false;
}
EOJS
print header,
      start_html( -TITLE   => "My Title",
                  -SCRIPT  => {-code=>$js}),
      start_form,
      submit(-NAME=>"Page",
             -VALUE=>"Submit",
             -ONCLICK=>"return someChecked(this.form);"),
      checkbox("Test",'','ON','A'),
      checkbox("Test",'','ON','B'),
      end_form,
      end_html;

Update: Added checkboxes to make the example more sensible.
