Bekräfta att cellvärdet uppfyller datavalideringsreglerna

Introduktion

Aspose.Cells for Node.js via C++ tillhandahåller metoden Cell.getValidationValue() för att validera cellvärden programmatiskt. Om värdet i en cell inte uppfyller datavalideringsregeln för den cellen, returneras false, annars true.

Följande exempel illustrerar hur metoden Cell.getValidationValue() fungerar. Först matar den in värdet 3 i C1. Eftersom detta inte uppfyller datavalideringsregeln, returnerar metoden false. Sedan matar den in värdet 15 i C1. Eftersom detta värde uppfyller datavalideringsregeln, returnerar metoden true. På samma sätt returnerar den false för värdet 30.

const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Instantiate the workbook from sample Excel file
const workbook = new AsposeCells.Workbook(dataDir + "sample.xlsx");
// Access the first worksheet
const worksheet = workbook.getWorksheets().get(0);
// Access Cell C1
// Cell C1 has the Decimal Validation applied on it.
// It can take only the values Between 10 and 20
const cell = worksheet.getCells().get("C1");
// Enter 3 inside this cell
// Since it is not between 10 and 20, it should fail the validation
cell.putValue(3);
// Check if number 3 satisfies the Data Validation rule applied on this cell
console.log("Is 3 a Valid Value for this Cell: " + cell.getValidationValue());
// Enter 15 inside this cell
// Since it is between 10 and 20, it should succeed the validation
cell.putValue(15);
// Check if number 15 satisfies the Data Validation rule applied on this cell
console.log("Is 15 a Valid Value for this Cell: " + cell.getValidationValue());
// Enter 30 inside this cell
// Since it is not between 10 and 20, it should fail the validation again
cell.putValue(30);
// Check if number 30 satisfies the Data Validation rule applied on this cell
console.log("Is 30 a Valid Value for this Cell: " + cell.getValidationValue());

Output

 Is 3 a Valid Value for this Cell: false

Is 15 a Valid Value for this Cell: true

Is 30 a Valid Value for this Cell: false
