I'm getting a data that would be the first three digits alphabetic characters and the other 4 numeric (A vehicle license plate).
I saw in a site that to receive only letters in Jquey Mask, just use the "A"
Example:
$('.placa').mask('AAA-0000');
But using this example, the user can insert numbers before the hyphen without any problems ...
Does anyone know how I can solve this?
I'm going to try to leave this very complete answer since this question is very interesting and I myself was looking for it some time ago and I believe that other people will also look for it.
In this example only
Very simple using the jQuery Masked Input plugin, in the example there are 3 fields, one text only, another text and number, and finally just number.
$(function() {
$('#apenasnumero').mask('(99) 9999-9999');
$('#apenasletra').mask('aaaaaaaa');
$('#letrasnumeros').mask('********');
});<head>
