将 Excel 转换为带有工具提示的 HTML
在生成的HTML中可能会出现文字被截断的情况，你想在悬停事件中显示完整文本作为工具提示。Aspose.Cells for JavaScript通过C++支持此功能，提供了HtmlSaveOptions.addTooltipText属性。将HtmlSaveOptions.addTooltipText属性设置为true将把完整文本作为工具提示添加到生成的HTML中。
以下图片显示了生成的 HTML 文件中的工具提示。
以下代码示例加载源Excel文件并生成带有提示的输出HTML文件。
示例代码
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Add Tooltip to HTML Example</title>
</head>
<body>
<h1>Add Tooltip to HTML 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, HtmlSaveOptions } = 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();
// Instantiate a Workbook from the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Create HtmlSaveOptions and enable tooltip text
const options = new HtmlSaveOptions();
options.addTooltipText = true;
// Save workbook as HTML with the specified options
const outputData = workbook.save(SaveFormat.Html, options);
const blob = new Blob([outputData], { type: 'text/html' });
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'AddTooltipToHtmlSample_out.html';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download HTML File';
document.getElementById('result').innerHTML = '<p style="color: green;">HTML file created successfully! Click the download link to get the result.</p>';
});
