Aspose.Cells, Microsoft Excel tarafından desteklenmeyen kullanıcı tanımlı veya özel işlevleri uygulamak için kullanılan AbstractCalculationEngine sınıfını sağlar.
Bu makale, AbstractCalculationEngine aralığındaki değerlerin nasıl döndürüleceğini açıklayacaktır.
Aşağıdaki kod, AbstractCalculationEngine sınıfının kullanımını gösterir ve yöntemi aracılığıyla değer aralığını döndürür.
Bir sınıf oluşturun ve bir calculateCustomFunction fonksiyonu ekleyin. Bu sınıf AbstractCalculationEngine uygulamaktadır.

}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
const workbook = new Workbook(new Uint8Array(arrayBuffer));
const calcInstance = new CustomFunctionStaticValue();
const data = {};
calcInstance.calculate(data);
document.getElementById('result').innerHTML = '<p style="color: green;">Calculated Value:</p><pre>' + JSON.stringify(data.calculatedValue, function(key, value) {
if (value instanceof Date) return value.toISOString();

Şimdi yukarıdaki fonksiyonu programınızda kullanın
