                        panelHeight: "auto",
                        editable: false, //不允许手动输入
                        onLoadSuccess: function () { //数据加载完毕事件
                            var data = $(‘#OrderType‘).combobox(‘getData‘);
                            if (data.length > 0) {
                                $("#OrderType").combobox(‘select‘, data[0].typeName);
                            }
