 <script>
        $(function() {
            $(document).on('click', 'form', function () {

                var validate = true;
               var unanswered = new Array();

               // Loop through available sets
               $('.qselections').each(function () {
                // Question text
                var question = $(this).prev().text();
                // Validate
                if (!$(this).find('input').is(':checked')) {
                    // Didn't validate ... dispaly alert or do something
                    unanswered.push(question);

                    validate = false;
                }
            });

            if (unanswered.length > 0) {
                msg = "Please answer the following questions:\n" +         unanswered.join('\n'); 
                alert(msg);
            }
            return validate;
        });
    });
    </script>

Answer 1

    //try this script

    if(!$(this).find("input[name=radio]").is(':checked')){
        alert("hi");
    }

Answer 2

function clicked() {

            var validate = true;
           var unanswered = new Array();

           // Loop through available sets
           $('.qselections').each(function () {
            // Question text
            var question = $(this).prev().text();
            // Validate
            if (!$(this).find('input').is(':checked')) {
                // Didn't validate ... dispaly alert or do something
                unanswered.push(question);

                validate = false;
            }
        });

        if (unanswered.length > 0) {
            msg = "Please answer the following questions:\n" +         unanswered.join('\n'); 
            alert(msg);
        }
        return validate;
    }

我稍微修改了你的问题，对我来说效果很好。我想这只是代码部分的语法错误，而不是小提琴中的错误。交叉检查，让我知道。尝试并修改您的点击通话，使其像小提琴一样直接。
