数据透视表序列化&反序列化

在一个数据透视表中,你可以序列化当前数据透视表的状态,并可以在之后将保存的下来的数据恢复成数据透视表的状态。

数据透视表支持序列化/反序列化数据透视表。 通过serialize()方法获得的序列化信息只能应用在有相同数据源的数据透视表中。 序列化 & 反序列化 当前序列化支持以下数据: 字段, 选项配置, 筛选, 排序, 布局, 数据透视表位置, 主题 接口 API 示例代码
window.onload = function () { var spread = new GC.Spread.Sheets.Workbook(_getElementById('ss'), { sheetCount: 2 }); initSpread(spread); var pivotLayoutSheet = spread.getSheet(0); var pt = initPivotTable(pivotLayoutSheet); bindEvent(pt); }; function initSpread(spread) { spread.suspendPaint(); let sheet = spread.getSheet(1); sheet.name("DataSource"); sheet.setRowCount(117); sheet.setColumnWidth(0, 120); sheet.getCell(-1, 0).formatter("YYYY-mm-DD"); sheet.getRange(-1,4,0,2).formatter("$ #,##0"); let table = sheet.tables.add('tableSales', 0, 0, 117, 6); for(let i=2;i<=117;i++) { sheet.setFormula(i-1,5,'=D'+i+'*E'+i) } table.style(GC.Spread.Sheets.Tables.TableThemes["none"]); sheet.setArray(0, 0, pivotSales); let sheet0 = spread.getSheet(0); sheet0.name("PivotLayout"); spread.resumePaint(); } function initPivotTable(sheet) { let myPivotTable = sheet.pivotTables.add("myPivotTable", "tableSales", 1, 1, GC.Spread.Pivot.PivotTableLayoutType.outline, GC.Spread.Pivot.PivotTableThemes.light1); myPivotTable.suspendLayout(); myPivotTable.options.showRowHeader = true; myPivotTable.options.showColumnHeader = true; myPivotTable.add("salesperson", "Salesperson", GC.Spread.Pivot.PivotTableFieldType.rowField); myPivotTable.add("car", "Cars", GC.Spread.Pivot.PivotTableFieldType.rowField); myPivotTable.add("date", "Quarter", GC.Spread.Pivot.PivotTableFieldType.columnField); let groupInfo = { originFieldName: "date", dateGroups: [{ by: GC.Pivot.DateGroupType.quarters }] }; myPivotTable.group(groupInfo); myPivotTable.add("total", "Totals", GC.Spread.Pivot.PivotTableFieldType.valueField, GC.Pivot.SubtotalType.sum); let itemList = ["Alan","John", "Tess"]; myPivotTable.labelFilter("Salesperson", { textItem: { list: itemList, isAll: false } }); let carList = ["Audi","BMW","Mercedes"]; myPivotTable.labelFilter("Cars", { textItem: { list: carList, isAll: false } }); let panel = new GC.Spread.Pivot.PivotPanel("myPivotPanel", myPivotTable, document.getElementById("panel")); panel.sectionVisibility(GC.Spread.Pivot.PivotPanelSection.fields + GC.Spread.Pivot.PivotPanelSection.area); myPivotTable.resumeLayout(); myPivotTable.autoFitColumn(); return myPivotTable; } function _getElementById(id) { return document.getElementById(id); } function bindEvent(pt){ _getElementById("Serialize").addEventListener("click", function(event){ let info = JSON.stringify(pt.serialize(), null, 2); _getElementById("serializeInfo").value = info; }); _getElementById("Deserialize").addEventListener("click", function(event){ try { let info = JSON.parse(_getElementById("serializeInfo").value); pt.deserialize(info); } catch (e) { alert("invalid serialize info!"); } }); }
