从ODS文件中读取图表副标题
Aspose.Cells提供使用Chart.subTitle属性读取ODS文件中图表副标题的能力。以下示例代码加载示例ODS文件，并使用Chart.subTitle属性读取图表副标题，然后在控制台窗口中打印。请参考以下代码的控制台输出。
示例代码
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example - Get Chart Subtitle</title>
</head>
<body>
<h1>Get Chart Subtitle Example</h1>
<input type="file" id="fileInput" accept=".ods,.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, Utils } = 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 or ODS 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));
// Accessing the first worksheet in the workbook
const worksheet = workbook.worksheets.get(0);
// Accessing the first chart inside the worksheet
const chart = worksheet.charts.get(0);
// Accessing chart subtitle text (converted from getSubTitle().getText())
const subtitleText = chart.subTitle.text;
console.log("Chart Subtitle: " + subtitleText);
document.getElementById('result').innerHTML = '<p>Chart Subtitle: ' + (subtitleText ?? '') + '</p>';
});
</script>
