    function load_saved_exam_data() {
        var tableData = '';
        jQuery.post('<?php echo site_url("administrator/active_exam_c/load_activate_exams") ?>', function (e) {
            if (e === undefined || e.length === 0 || e === null) {
                tableData += '<tr><th colspan="8" class="alert alert-warning text-center"> -- No Data Found -- </th></tr>';
                jQuery('.activate_exam_tbl tbody').html('').append(tableData);
            } else {
                jQuery.each(e, function (index, qData) {
//                    alert(qData.act_status);
                    var checked;
                    if (qData.act_status == 1) {
                        checked = 'checked';
                    } else {
                        checked = '';
                    }

                    index++;
                    tableData += '<tr>';
                    tableData += '<td>' + index + '</td>';
                    tableData += '<td>' + qData.exam_name + '</td>';
                    tableData += '<td>' + qData.start_date + '</td>';
                    tableData += '<td>' + qData.end_date + '</td>';
                    tableData += '<td>' + qData.ex_session_id + '</td>';
                    tableData += '<td><div class="btn-group">'
                            + '<div class="onoffswitch"><input type="checkbox" onclick="handleClick(this);" name="onoffswitch" class="onoffswitch-checkbox" value="' + qData.exm_id + '" id="myonoffswitch" ' + checked + ' ><label class="onoffswitch-label" for="myonoffswitch"><span class="onoffswitch-inner"></span><span class="onoffswitch-switch"></span></label></div></div></td>';
                    tableData += '<td><div class="btn-group"><button class="btn btn-danger delete_exam_act"  value="' + qData.exm_id + '"><i class="fa fa-trash-o fa-lg"></i>&nbsp;Remove</button></div></td>';
                    tableData += '</tr>';
                });

                jQuery('.activate_exam_tbl tbody').html('').append(tableData);
            }
        }, "json");
    }



    function handleClick(cb) {
        var activation_val = jQuery(cb).val();
        var activation_checked;
        if (cb.checked) {
            activation_checked = '1';
        } else {
            activation_checked = '0';
        }
        var data = {
            activation_val: activation_val,
            activation_checked: activation_checked

        };
        jQuery.post('<?php echo site_url("administrator/active_exam_c/update_exam_activation") ?>', data, function (d) {
//            console.log(d);
            if (d.status == 1) {
                swal("success!", "Successfully Updated!", "success");

            } else {
                swal("Only one exam can be activated..", "Please deactivate active exam and try again!", "warning");

            }
        }, 'json');
    }
