前台取数据：
$.post("Default.aspx", { flag: "ViewPage" }, function (dataStr) {  
                var dataObj = eval("(" + dataStr + ")");  
                if (dataObj.error != "") {  
                    $("#myGrid").hide();  
                    $("#errorTip").show();  
                    $("#errorTip").html(dataObj.error);  
                } else {  
                    if (dataObj.data.length > 0) {  
                        for (var i = 0; i < dataObj.data.length; i++) {  
                            var d = (data[i] = {});  
                            d["PageID"] = dataObj.data[i]["PageID"];  
                            d["PageName"] = dataObj.data[i]["PageName"];  
                            d["PageSeq"] = dataObj.data[i]["PageSeq"];  
                            d["DisplayInterval"] = dataObj.data[i]["DisplayInterval"];  
                            d["Display"] = dataObj.data[i]["Display"];  
                        }  
                        grid = new Slick.Grid("#myGrid", data, columns, options);  
                    }  
                }  
            });
