如果你想使用区域选择模式，你只需要创建一个带有选项 {rangeSelectMode: true} 的公式编辑器。例如：
你可以使用FormulaTextBox的workbook方法把公式编辑器附加到workbook上。例如：
如果 fbx1.workbook() 不含参数, 它将脱离范围选择。
你可以使用FormulaTextBox的text方法获取公式编辑器的文本。例如：
你可以使用FormulaTextBox的destory方法删除对应的DOM元素。例如：
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {sheetCount: 2});
initSpread(spread);
var fbx = new GC.Spread.Sheets.FormulaTextBox.FormulaTextBox(document.getElementById('formulaBar'), {rangeSelectMode: true});
fbx.workbook(spread);
document.getElementById('getValue').onclick = function () {
document.getElementById('rangeText').textContent = fbx.text();
};
};
function initSpread(spread) {
var spreadNS = GC.Spread.Sheets;
var sheet = spread.getActiveSheet();
sheet.suspendPaint();
var cfs = sheet.conditionalFormats;
var Range = spreadNS.Range;
var row = 0, col = 1;
sheet.getCell(row, ++col).value("Icon Set").font("700 11pt Calibri");
sheet.addSpan(row, col, 1, 10);
sheet.addSpan(row + 6, col, 1, 10);
row++;
for (var column = col; column < col + 10; column++) {
sheet.getCell(row, column).value(-50);
sheet.getCell(row + 1, column).value(-25);
sheet.getCell(row + 2, column).value(0);
sheet.getCell(row + 3, column).value(25);
sheet.getCell(row + 4, column).value(50);
sheet.getCell(row + 6, column).value(-50);
sheet.getCell(row + 7, column).value(-25);
sheet.getCell(row + 8, column).value(0);
sheet.getCell(row + 9, column).value(25);
sheet.getCell(row + 10, column).value(50);
}
var rowCount = 5;
cfs.addIconSetRule(0, [new Range(row, col, rowCount, 1)]);
cfs.addIconSetRule(1, [new Range(row, ++col, rowCount, 1)]);
cfs.addIconSetRule(2, [new Range(row, ++col, rowCount, 1)]);
cfs.addIconSetRule(3, [new Range(row, ++col, rowCount, 1)]);
cfs.addIconSetRule(4, [new Range(row, ++col, rowCount, 1)]);
cfs.addIconSetRule(5, [new Range(row, ++col, rowCount, 1)]);
cfs.addIconSetRule(6, [new Range(row, ++col, rowCount, 1)]);
cfs.addIconSetRule(7, [new Range(row, ++col, rowCount, 1)]);
cfs.addIconSetRule(8, [new Range(row, ++col, rowCount, 1)]);
cfs.addIconSetRule(9, [new Range(row, ++col, rowCount, 1)]);
col = 1;
cfs.addIconSetRule(10, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(11, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(12, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(13, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(14, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(15, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(16, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(17, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(18, [new Range(row + 6, ++col, rowCount, 1)]);
cfs.addIconSetRule(19, [new Range(row + 6, ++col, rowCount, 1)]);
sheet.resumePaint();
