可能的使用场景
Microsoft Excel公式在不同地区或语言中可能有不同的名称。例如，SUM函数在德语中称为SUMME。Aspose.Cells不能使用非英语的函数名称。在Microsoft Excel VBA中，有Range.FormulaLocal属性，返回该函数的本地名称。Aspose.Cells for JavaScript通过C++也提供了用于此目的的Cell.formulaLocal属性。然而，此属性仅在你实现GlobalizationSettings.localFunctionName(standardName)方法时有效。
实现类似于Excel VBA Range.FormulaLocal的Cell.FormulaLocal
以下示例代码说明如何实现 GlobalizationSettings.localFunctionName(standardName) 方法。该方法返回标准函数的本地名称。如果标准函数名为 SUM ，它返回 UserFormulaLocal_SUM。你可以根据自己的需要修改代码，并返回正确的本地函数名，例如在德语中 SUM 为 SUMME，俄语中 TEXT 为 ТЕКСТ。请同时参考下面的示例代码输出。
示例代码
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Aspose.Cells Globalization Example</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample">Run Example</button>
<a id="downloadLink" style="display: none;">Download Result</a>
<div id="result"></div>
</body>
<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">
const { Workbook, SaveFormat } = AsposeCells;
AsposeCells.onReady({
license: "/lic/aspose.cells.enc",
fontPath: "/fonts/",
fontList: [
"arial.ttf",
"NotoSansSC-Regular.ttf"
]
}).then(() => {
console.log("Aspose.Cells initialized");
});
// Define GS class implementing localization override
class GS extends AsposeCells.GlobalizationSettings {
localFunctionName(standardName) {
// Change the SUM function name as per your needs.
if (standardName === "SUM") {
return "UserFormulaLocal_SUM";
}
// Change the AVERAGE function name as per your needs.
if (standardName === "AVERAGE") {
return "UserFormulaLocal_AVERAGE";
}
return "";
}
}
document.getElementById('runExample').addEventListener('click', () => {
const resultDiv = document.getElementById('result');
// Create workbook
const wb = new Workbook();
// Assign GlobalizationSettings implementation class
wb.settings.globalizationSettings = new GS();
// Access first worksheet
const ws = wb.worksheets.get(0);
// Access some cell
const cell = ws.cells.get("C4");
// Assign SUM formula and get its FormulaLocal
cell.formula = "SUM(A1:A2)";
const formulaLocal1 = cell.formulaLocal;
// Assign AVERAGE formula and get its FormulaLocal
cell.formula = "=AVERAGE(B1:B2, B5)";
const formulaLocal2 = cell.formulaLocal;
resultDiv.innerHTML = `<p>Formula Local 1: ${formulaLocal1}</p><p>Formula Local 2: ${formulaLocal2}</p>`;
// Save the workbook and provide download link
const outputData = wb.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'output.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Excel File';
});
</script>
</html>
控制台输出
Formula Local: =UserFormulaLocal_SUM(A1:A2)
Formula Local: =UserFormulaLocal_AVERAGE(B1:B2,B5)
