设定公式

在SpreadJS中,可以使用Worksheet类的 setFormula 方法在单元格中设置公式。下面的图像显示了在B列上应用不同公式后的结果值。



在单元格中设置公式

本示例在单元格中设置公式。

window.onload = function()
{
   var spread =
   new GC.Spread.Sheets.Workbook(document.getElementById("ss"),
   {sheetCount:3});
   var activeSheet = spread.getActiveSheet();
   activeSheet.setRowCount(5);
   activeSheet.setColumnCount(2);
   activeSheet.getRange(-1, 1, -1, 1)
   .backColor("lightYellow")
   .width(120);
   activeSheet.setValue(0, 0, 10);
   activeSheet.setValue(1, 0, 20);
   activeSheet.setValue(2, 0, 30);
   activeSheet.setValue(3, 0, 40);
   activeSheet.setValue(4, 0, 50);

   // 设置SUM函数(所有参数值的和)。
   activeSheet.setFormula(0, 1, "SUM(A1:A5)");
 
   // 设置PRODUCT函数(所有参数值的乘积)。
   activeSheet.setFormula(1, 1, "PRODUCT(A1:A5)");

   // 设置AVERAGE函数(对所有参数值进行平均)。
   activeSheet.setFormula(2, 1, "AVERAGE(A1:A5)");

  // 设置单元格(0,0)和单元格(4,0)的和。
  activeSheet.setFormula(3, 1, "A1 + A5");

  /* 如果单元格(0,0)的值大于10,则将单元格(0,0)乘以2,
    否则就乘以3。*/
   activeSheet.setFormula(4, 1, "IF(A1>10, A1*2, A1*3)");
}

设置引用交叉表公式

你可以在公式中引用其他表格。下面的图片显示了第一个表单。




下图显示了第二个表单。




本例使用了跨表单引用。

window.onload = function()
{
   var spread =
   new GC.Spread.Sheets.Workbook(document.getElementById("ss"),{sheetCount:3});
   var activeSheet = spread.getActiveSheet();
   var sheet1 = spread.getSheet(0),
   sheet2 = spread.getSheet(1);
   sheet1.name("Sheet1");
   sheet2.name("Sheet2");
       
   sheet1.setValue(0, 0, 1000);
   sheet1.setValue(1, 0, 2000);
   sheet1.setValue(2, 0, 3000);
   sheet1.setValue(3, 0, 4000);
   sheet1.getRange(0, 0, 4, 1).backColor("lightPink");
   sheet2.setValue(0, 0, 5000);
   sheet2.getRange(0, 0, 1, 1).backColor("lightCyan");

   // 设置“Sheet1: total of cell(0,0) to cell(3,0)”和“Sheet2: cell(0,0)”的求和公式。
   sheet2.setFormula(1, 1, "SUM(Sheet1!A1:A4) + Sheet2!A1");
   sheet2.getRange(1, 1, 1, 1).backColor("lemonChiffon");
}

设置SUBTOTAL公式

您可以设置SUBTOTAL公式,如下图所示。




本例使用subtotal公式。

$(document).ready(function ()
{
    var spread =
    new GC.Spread.Sheets.Workbook(document.getElementById("ss"),
    {sheetCount:3});
   
    var activeSheet = spread.getActiveSheet();
    activeSheet.setColumnCount(2);
    activeSheet.options.colHeaderAutoText = GC.Spread.Sheets.HeaderAutoText.blank;
    activeSheet.setText(0, 1, "Value", GC.Spread.Sheets.SheetArea.colHeader);
    activeSheet.options.gridline = {showHorizontalGridline: false};
    activeSheet.setText(3, 0, "Sub-Total1");
    activeSheet.setText(7, 0, "Sub-Total2");
    activeSheet.setText(8, 0, "Aggregate");
    activeSheet.getRange(3, -1, 1, -1).backColor("lemonChiffon");
    activeSheet.getRange(7, -1, 1, -1).backColor("lemonChiffon");
    activeSheet.getRange(8, -1, 1, -1).backColor("lightPink");
    activeSheet.setValue(0, 1, 100);
    activeSheet.setValue(1, 1, 200);
    activeSheet.setValue(2, 1, 300);
    activeSheet.setValue(4, 1, 400);
    activeSheet.setValue(5, 1, 500);
    activeSheet.setValue(6, 1, 600);
  
   // 使用SUBTOTAL函数设置小计和聚合。
   activeSheet.setFormula(3, 1, "SUBTOTAL(9,B1:B3)");
   activeSheet.setFormula(7, 1, "SUBTOTAL(9,B5:B7)");
   activeSheet.setFormula(8, 1, "SUBTOTAL(9,B1:B7)");
});
