使用 JavaScript 通过 C++ 生成 HTML

将Excel工作簿转换为HTML

Aspose.Cells API 提供了导出电子表格为 HTML 格式的支持。为此，Aspose.Cells 使用 HtmlSaveOptions 类，提供控制输出 HTML 各个方面的灵活性。

以下代码示例演示如何使用 JavaScript 通过 C++ 将工作簿保存为 HTML 文件：

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Example</title>
    </head>
    <body>
        <h1>Aspose.Cells - Convert Excel to HTML</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Convert to HTML</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");
        });

        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));

            // Saving the workbook to HTML format
            const outputData = workbook.save(SaveFormat.Html);
            const blob = new Blob([outputData], { type: 'text/html' });
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'out.html';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download HTML File';

            document.getElementById('result').innerHTML = '<p style="color: green;">Conversion completed! Click the download link to get the HTML file.</p>';
        });
    </script>
</html>

将Excel工作簿转换为MHTML文件

MHTML将普通HTML与外部资源（如图片、动画、音频等）合并成一个文件。这些文件通常扩展名为.mht，用于电子邮件。Aspose.Cells支持读取和写入MHTML文件。

以下代码示例演示如何使用 JavaScript 通过 C++ 将工作簿保存为 MHTML 文件：

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Example - Save as MHT</title>
    </head>
    <body>
        <h1>Save Excel as MHT 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");
        });

        document.getElementById('runExample').addEventListener('click', async () => {
            const fileInput = document.getElementById('fileInput');
            const resultDiv = document.getElementById('result');
            if (!fileInput.files.length) {
                resultDiv.innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
                return;
            }

            const file = fileInput.files[0];
            const arrayBuffer = await file.arrayBuffer();

            // Load your source workbook from the uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Save file to MHT format
            const outputData = workbook.save(SaveFormat.MHtml);
            const blob = new Blob([outputData], { type: 'application/octet-stream' });
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'out.mht';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download MHT File';

            resultDiv.innerHTML = '<p style="color: green;">File converted to MHT successfully! Click the download link to get the result.</p>';
        });
    </script>
</html>
