Debug JQuery/JavaScript?

Is it possible to be on a live page and "debug" the script below?

<script>
    function SaveValidation() {
        var surveydata = "";
        $('.rblsurvey').each(function () {
            debugger;
            var checked_radio = $("[id*=" + $(this).context.id + "] input:checked");
            var value = checked_radio.val();
                    
            var question = $(this).context.className.replace("rblsurvey rblMultiList_", "");
            surveydata = surveydata + question + "," + value + "|";
            //alert(surveydata);         
            $("#hdnsurveyvalues").val(surveydata);
        });

        $(".chks").each(function (index) {
            debugger
            var questionid = $(this).attr("class").replace("chks chkquestions_", "");
            var answerid = "";

            $(this).find(":checked").each(function (index) {
                answerid = questionid + "," + $(this).val() + "|" + answerid;
            });
                alert(answerid)                                        
            $("#hdnsurveyvaluesChk").val(answerid);
        });

              
    }
</script>
