TextBoxar kan förbättra uttryckssättet i våra dokument och diagram, och att tillämpa olika justeringar på olika delar av en TextBox kan hjälpa till att lyfta fram intressanta punkter för läsare. Men standardjusteringen av TextBox möter inte alla våra behov. För detta kan du behöva justera varje TextBox för att möta dina målkrav. Om du inte har många TextBox-objekt att finjustera är du lyckligt lottad. Om det finns så många TextBoxar att justera, tror jag att du kommer att ha problem. Oroa dig inte nu, Aspose.Cells tillhandahåller ett API-gränssnitt för att hjälpa dig med just detta.
Följande kodexempel tillämpar textjustering på en TextBox.
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Aspose.Cells Add TextBox 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, 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');
let workbook;
if (fileInput.files.length) {
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
workbook = new Workbook(new Uint8Array(arrayBuffer));
} else {
workbook = new Workbook();
}
const worksheet = workbook.worksheets.get(0);
const shapes = worksheet.shapes;
// add a TextBox
const shape = shapes.addTextBox(2, 0, 2, 0, 50, 120);
shape.text = "This is a test.";
// set alignment
shape.textHorizontalAlignment = AsposeCells.TextAlignmentType.Center;
shape.textVerticalAlignment = AsposeCells.TextAlignmentType.Center;
// Saving the modified Excel file
const outputData = workbook.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'result.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Operation completed successfully! Click the download link to get the modified file.</p>';
});
</script>
</html>
Du kan också ändra textjusteringen för vissa delar av en TextBox-form med rätt HTML-text. Följande exempel kod tillämpar textjustering på del av texten i TextBoxen.
<!DOCTYPE html>

</head>
<body>

<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample">Run Example</button>
<a id="downloadLink" style="display: none;">Download Result</a>

<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">
const { Workbook, SaveFormat, MsoDrawingType, Utils } = AsposeCells;
AsposeCells.onReady({

}).then(() => {

});
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');

return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Load source workbook from the selected file
const sourceWb = new Workbook(new Uint8Array(arrayBuffer));
// Access the target textbox whose text is to be aligned
const sourceTextBox = sourceWb.worksheets.get(0).shapes.get(0);
// Create an object of the target workbook
const destWb = new Workbook();
// Access the first worksheet from the collection
const _sheet = destWb.worksheets.get(0);
// Create new textbox
const _textBox = _sheet.shapes.addShape(MsoDrawingType.TextBox, 1, 0, 1, 0, 200, 200);
// Use Html string from a template file textbox
_textBox.htmlText = sourceTextBox.htmlText;
// Save the workbook and provide download link
const outputData = destWb.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'Output.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Text box HTML copied successfully! Click the download link to get the modified file.</p>';
