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>
