One example would be to enforce input to only accept the adhaar number format
一个例子是强制输入只接受 adhaar 数字格式
$('[data-type="adhaar-number"]').keyup(function() {
var value = $(this).val();
value = value.replace(/\D/g, "").split(/(?:([\d]{4}))/g).filter(s => s.length > 0).join("-");
$(this).val(value);
});
$('[data-type="adhaar-number"]').on("change, blur", function() {
var value = $(this).val();
var maxLength = $(this).attr("maxLength");
if (value.length != maxLength) {
$(this).addClass("highlight-error");
} else {
$(this).removeClass("highlight-error");
}
});.highlight-error {
border-color: red;

I am not interested in giving u everything, but I will point you in the right direction. Use regular expressions.
我对给你一切都不感兴趣，但我会为你指明正确的方向。使用正则表达式。
This regex will help your case but you need to put in your effort on how it must be used in your situation.
此正则表达式将有助于您的情况，但您需要努力了解如何在您的情况下使用它。
console.log(/\d{4}-\d{4}-\d{4}-\d{4}/.test('1000-1000-1000-1002'));
