<script>$("#gettag").click(function(){        var work_id = $("#work_id").attr("value");        $.ajax({            url: "?m=tags&c=index&a=ajax_show&dosubmit=1&type=1&workid="+work_id,            type: "get",            data:{},            dataType: "json",            error: function(){                alert(\'Error loading XML document\');            },            success: function(data){            if(data["error"] == 0){            var selectValues = data["data"];            var output = [];            $.each(selectValues, function(key, value)            {            output.push(\'<li><input type="checkbox" value="\'+ value["tag_id"] +\'">\'+ value["tag_name"] +\'</li>\');            });            $(\'#tags\').html(output.join(\'\'));            }else{            alert(data["message"]);            }            }        });    });</script>
