Nascondere la visualizzazione di valori Zero nel Foglio di Lavoro con JavaScript tramite C++

Contents
[ ]

Per nascondere i valori zero in un foglio di lavoro in Microsoft Excel (ad esempio Microsoft Excel 2003):

  1. Dal menu Strumenti, selezionare Opzioni, e quindi selezionare la scheda Visualizza.
  2. Deselezionare l’opzione Valori zero.
  3. Fai clic su OK.

Vedi il seguente esempio di codice che dimostra come nascondere gli zeri usando Aspose.Cells for JavaScript tramite C++.

        <h1>Hide Zero Values 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, Worksheet, Cell, Utils } = AsposeCells;

        AsposeCells.onReady({

        });

        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 uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Get First worksheet of the workbook
            const sheet = workbook.worksheets.get(0);

            // Hide the zero values in the sheet
            sheet.displayZeros = false;

            // Save the workbook and provide download link
            const outputData = workbook.save(SaveFormat.Xlsx);
            const blob = new Blob([outputData]);
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'outputfile.out.xlsx';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download Modified Excel File';

            document.getElementById('result').innerHTML = '<p style="color: green;">Operation completed successfully! Click the download link to get the modified file.</p>';
