用 JavaScript 通过 C++ 查找工作表是否为对话框表

可能的使用场景
对话框工作表是包含对话框的旧格式工作表。此类工作表可以由老版本的Excel（如2003）插入，如截图所示，也可以通过VBA在较新版本（如Excel 2016）中插入。
你可以使用 Aspose.Cells for JavaScript 通过 C++ 提供的 Worksheet.type 属性判断工作表是否为对话框表。如果返回枚举值 SheetType.Dialog，则代表你面对的是对话框表。
查找工作表是否为对话框工作表
以下示例代码加载了包含对话框工作表的示例Excel文件（64716820.xlsx）。它检查Worksheet.type属性，将其与SheetType.Dialog比较，然后输出信息。请参阅下面的控制台输出以获取更多帮助。

<h1>Detect if Worksheet Is a Dialog Sheet</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />

}).then(() => {
console.log("Aspose.Cells initialized");
});
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
if (!fileInput.files.length) {
document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Instantiating a Workbook object from the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Access first worksheet
const ws = workbook.worksheets.get(0);
// Find if the sheet type is dialog and print the message
if (ws.type === AsposeCells.SheetType.Dialog) {
document.getElementById('result').innerHTML = '<p style="color: green;">Worksheet is a Dialog Sheet.</p>';
} else {
document.getElementById('result').innerHTML = '<p>Worksheet is NOT a Dialog Sheet.</p>';
}
});
</script>

控制台输出
Worksheet is a Dialog Sheet.
