Are you looking for a way to aadhar number validation using JavaScript? Look no further because we have got you covered. In this article, we will provide you with a step-by-step guide to validate Aadhaar card numbers using JavaScript. You will also learn about the importance of Aadhaar card validation and the benefits it provides. So let’s get started.
Aadhaar card number is a unique identification card issued by the Indian government. It contains a 12-digit number that serves as a unique identifier for Indian citizens. The Aadhaar card is used for various purposes such as opening a bank account, applying for a passport, and availing of government schemes.
Aadhaar card number validation is essential because it helps ensure that the Aadhaar card number entered is correct and belongs to a valid individual. This validation process can prevent fraud and identity theft. It also helps in the smooth functioning of various government schemes and services.
Regular expressions are a powerful tool used for pattern matching. We can use regular expressions to validate the Aadhaar card number entered by the user. The following regular expression can be used to validate the Aadhaar card number:
var aadhaar_regex = /^[2-9]{1}[0-9]{3}[0-9]{4}[0-9]{4}$/;
Once we have created the regular expression, we can use it to validate the Aadhaar card number entered by the user. The following code can be used to validate the Aadhaar card number:
function validateAadhaar(aadhaar) {
if (aadhaar.match(aadhaar_regex)) {
return true;
} else {
return false;
}
}
The final step is to display the validation result to the user. We can use the following code to display the validation result:
var aadhaar = document.getElementById("aadhaar").value;
if (validateAadhaar(aadhaar)) {
document.getElementById("result").innerHTML = "Aadhaar card number is valid";
} else {
document.getElementById("result").innerHTML = "Invalid Aadhaar card number";
}
