Introduzione
In Excel, è possibile selezionare un intervallo, copiare l’intervallo, quindi incollarlo con opzioni specifiche nello stesso foglio di lavoro, in altri fogli di lavoro o in altri file.
Copiare intervalli usando Aspose.Cells for JavaScript tramite C++
Aspose.Cells for JavaScript tramite C++ fornisce alcuni metodi sovraccaricati Range.copy(Range, PasteOptions) per copiare l’intervallo. E Range.copyStyle(Range) copiare solo lo stile dell’intervallo; Range.copyData(Range) copiare solo i valori dell’intervallo.
Copia Intervallo
Creare due intervalli: l’intervallo origine, l’intervallo destinazione, quindi copiare l’intervallo origine in quello destinazione con il metodo Range.copy.
Vedere il codice seguente:
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Example Title</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 } = 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();
}
// Get all the worksheets in the book.
let worksheets = workbook.worksheets;
// Get the first worksheet in the worksheets collection.
let worksheet = workbook.worksheets.get(0);
// Create a range of cells.
let sourceRange = worksheet.cells.createRange("A1", "A2");
// Input some data with some formattings into A few cells in the range.
sourceRange.get(0, 0).value = "Test";
sourceRange.get(1, 0).value = 123;
// Create target range of cells.
let targetRange = worksheet.cells.createRange("B1", "B2");
// Copy source range to target range in the same worksheet
targetRange.copy(sourceRange);
// Create target range of cells.
workbook.worksheets.add();
worksheet = workbook.worksheets.get(1);
targetRange = worksheet.cells.createRange("A1", "A2");
// Copy source range to target range in another worksheet
targetRange.copy(sourceRange);
// Copy to another workbook
const anotherWorkbook = new Workbook();
worksheet = workbook.worksheets.get(0);
targetRange = worksheet.cells.createRange("A1", "A2");
// Copy source range to target range in another workbook
targetRange.copy(sourceRange);
const outputData = workbook.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;">Operation completed successfully!</p>';
});

Incolla l’intervallo con opzioni
Aspose.Cells for JavaScript via C++ supporta l’incollaggio dell’intervallo con tipi specifici.

Copia solo i dati dell’intervallo
Inoltre, puoi copiare i dati con il metodo Range.copyData come mostrato nel seguente codice:
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Copy Range 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');
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));
// Get all the worksheets in the book.
const worksheets = workbook.worksheets;
// Get the first worksheet in the worksheets collection.
const worksheet = worksheets.get(0);
// Create a range of cells.
const sourceRange = worksheet.cells.createRange("A1", "A2");
// Input some data with some formattings into a few cells in the range.
sourceRange.get(0, 0).value = "Test";
sourceRange.get(1, 0).value = 123;
// Create target range of cells.
const targetRange = worksheet.cells.createRange("B1", "B2");
// Copy the data of source range to target range
targetRange.copyData(sourceRange);
// 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 = 'output.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Range copied successfully! Click the download link to get the modified file.</p>';
});
