楼主这么试试:
JScript code
<script>     $(document).ready(function(){        $("#allcheckbox").click(function(){            if(this.checked){                $("input[name='foodid']").attr("checked", "true");            }else{                $("input[name='foodid']").attr("checked", "");            }        });     });</script>
