I have a project in which i have an html page.There I have a Submit Button using which i have to call a perl subroutine, carry out some function and return the value. The problem is that i am not able to pass the value to the subroutine. Also is there a way to use $_Get or $_Post i n perl??

I am posting my script below

#!/usr/bin/perl -w
 
 
  use CGI::Ajax;
  use CGI;

  sub functions {
    my $Fn = $_Get['Function'];
    my $input = shift;
    if(1)
    {
    return ("True");
    }
    if(0)
    {
    return ("False");
    }
  }
  
    sub Show_HTML {
    my $html = <<EOT;
  <HTML>
  <HEAD><title>Perl and HTML</title>
  </HEAD>
  <BODY>

  <script type="text/javascript">

    function CheckIsNumeric()
    {
    var AsciiCode = event.keyCode;
    if ((AsciiCode < 48) || (AsciiCode > 57))
        {
            alert('Please enter only numbers.');
            event.cancelBubble = true; 
            event.returnValue = false; 
        }
    }
  </script>
  <Form method="Get">
    <select name="Function">
    <option value="0" selected>(please select:)</option>
    <option value="1">Func1</option>
    <option value="2">Func2</option>
    </select>
    &nbsp;
    &nbsp;
    Enter a number:&nbsp;
    <input type="text" name="Number" id="myText" size="6"onkeypress ="
+CheckIsNumeric()"/>
    &nbsp;
    &nbsp;
    Enter a function:&nbsp;
    <input type="text" name="fns" id="URI" size="25">
    <input type='Submit' onsubmit="functions('fns');" value='Submit' /
+>
  </Form> 
  <hr>
    <div id="resultdiv">
    </div>
    <br>
  </BODY>
  </HTML>
EOT
    return $html;
  }
  
  my $cgi = new CGI();
  my $pjx = new CGI::Ajax( 'functions' => \&functions );
  
  print $pjx->build_html($cgi,\&Show_HTML);
