跨工作簿公式

SpreadJS支持跨工作簿公式,可以通过以下语法使用:

'filePath[workbookName]sheetName'!CellOrRangeAddress

例如: “=[Calc.xlsx]Sheet1!A1”, “=[Calc.xlsx]Sheet1!A1:B3”

注意: 跨工作簿引用不支持动态数组溢出或 INDIRECT 函数。

更新引用

您可以使用工作簿 JSON 设置或更新外部源的数据。updateExternalReference方法接受链接名称、JSON 数据和文件路径等参数。

下面的 GIF 说明了当“Workbook 1”中的 A1 单元格更新时,SpreadJS 如何更新“Workbook 1”和“Workbook 2”中设置的外部引用。

var spread1 = new GC.Spread.Sheets.Workbook(document.getElementById('ss1'), { sheetCount: 1 });
var spread2 = new GC.Spread.Sheets.Workbook(document.getElementById('ss2'), { sheetCount: 1 });
            

spread1.sheets[0].setValue(0, 0, 5);

var spread1Task;
function updateSpread1() {
    if (!spread1Task) {
        spread1Task = setTimeout(() => {
            spread1.updateExternalReference("calc.xlsx", spread2.toJSON());
            spread1Task = null;
        })
    }
}
var spread2Task;
function updateSpread2() {
    if (!spread2Task) {
        spread2Task = setTimeout(() => {
            spread2.updateExternalReference("result.xlsx", spread1.toJSON());
            spread2Task = null;
        })
    }
}

spread1.bind(GC.Spread.Sheets.Events.ValueChanged, updateSpread2)
spread1.bind(GC.Spread.Sheets.Events.RangeChanged, updateSpread2)
spread2.bind(GC.Spread.Sheets.Events.ValueChanged, updateSpread1)
spread2.bind(GC.Spread.Sheets.Events.RangeChanged, updateSpread1)


spread1.updateExternalReference("calc.xlsx", spread2.toJSON());
spread2.updateExternalReference("result.xlsx", spread1.toJSON());
spread1.sheets[0].setFormula(1, 0, "='[calc.xlsx]Sheet1'!A1");
spread2.sheets[0].setFormula(0, 0, "='[result.xlsx]Sheet1'!A1^2");

获取引用

您可以获取当前工作簿的跨工作簿引用列表。getExternalReferences方法返回一个对象数组,其中 包含文件名和跨工作簿引用的文件路径。

以下代码示例显示如何获取当前工作表中使用的外部引用列表。

var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 1 });
var sheet = spread.getActiveSheet();
sheet.setFormula(0, 0, "='[Jackson.xlsx]Sheet1'!A1");
sheet.setFormula(1, 0, "='[Petrosky]Sheet1'!A1");
console.log(spread.getExternalReferences());
// 输出
// Array(2)
// 0: { name: 'Jackson.xlsx', filePath: '' }
// 1: { name: 'Petrosky', filePath: '' }

使用SpreadJS设计器

SpreadJS 设计器通过“数据”>“查询和连接”功能区组中的“编辑链接”选项帮助更新工作表中的跨工作簿值。

它会打开以下对话框窗口,您可以在其中更新源。
