Code:

<?=js_asset('jquery.validate.js');?>
    $(document).ready(function(){
    $("#contactform").validate();
});

you have to add validation rules and submit handler there. For example:

Code:

<?=js_asset('jquery.validate.js');?>
    $(document).ready(function(){
    $("#contactform").validate({

     submitHandler:function(form) {
        
         form.submit();

        },

      rules: {
           input_name: {
              required: true,
              maxlength: 100
              
            },
                   input_address: {
                required: true
              }
    });
});

Edit: and you need script tags.
