我试图返回我的复选框的值你可以帮助我因为我仍然无法返回值，如果值为1我希望我的复选框中有一个支票

这是我的代码：

    <input  type="hidden" name="stud_no[]" value="<?php echo $row['student_no'];?>">


    <input  type="text" name="prelim[]" value="<?php echo $row['prelim_pts']?>"  id="prelim_<?php echo $row['student_no'];?>" class="txtprelim" ></td>
    <td><input  type="text" name="midterm[]" value="<?php echo $row['midterm_pts']?>"  id="midterm_<?php echo $row['student_no'];?>" class="txtmidterm" ></td>
    <td> <input  type="text" name="final[]" value="<?php echo $row['finals_pts']?>" id="final_<?php echo $row['student_no'];?>" class="txtfinal" ></td>

<td>

<input type="text" name="average[]" id="average_<?php echo $row['student_no']; ?>" value="<?php echo $row['average_pts']; ?>"  readonly="readonly"> 

</td>
<td><input type="checkbox" name="disable[]" id="able" value="<?php echo $row['disable_comp'];?>" class="dis"> </td>

<?php

    echo "</tr>";
    }
}

    ?>
    <input type="hidden" name="sec_no" value="<?php echo $_GET["section_no"]; ?>" />

    <script type="text/javascript">
    //var bIsFirebugReady = (!!window.console && !!window.console.log);

    $(document).ready(function(){

        p="";
        m="";
        f="";

 var computeValues = function(){
            var id = $(this).attr("id").replace("prelim_", "").replace("midterm_", "").replace("final_", "");
            p = $("#prelim_" + id).val();
            m = $("#midterm_" + id).val();
            f = $("#final_" + id).val();
            Compute(p, m, f, id);
        };

        $("input").bind('keyup', computeValues);

        function Compute(p, m, f, studno) {
            var average;
            average = parseFloat(p * 0.3) + parseFloat(m * 0.3) + parseFloat(f * 0.4);
            $("#average_" + studno).val(average.toFixed());     
        }

        $(".dis").change(function() {
            var val = $(this).val();
            if ($(this).is(':checked')) {
                var checked = $('input[type=checkbox]').is(':checked');
                $("input").unbind('keyup', computeValues);




            }
             else {
                $("input").bind('keyup', computeValues).trigger('keyup');

            }
        });
    });

var checked=$("#chkboxid").is(':checked');

checked将包含true或false

var x = $(this).prop('checked');
