I would like to be able to validate an input so that by pressing the "space" key there is no effect on the input.
This is what I have
if ($('#correo').val().trim() == "") {
mensajeAlert("El campo correo es obligatorio");
return false;
}
Currently, if the field is empty, it displays the error message.
Try this:
$(function() {
$('#correo').on('keypress', function(e) {
if (e.which == 32)
return false;
});
});
Here you can see the example Fiddle

Good afternoon Arnell, that code should work without problems, the only thing I can think of is that you do not have a good link to the jQuery library, yet try it in this other way using native JavaScript (I understand that if you include it in a function that you call when you click on the submit):
if (document.getElementById("correo").value.trim() == "") {
alert("El campo correo es obligatorio");
return false;
}
I also recommend that before making sure of the operation you use an alert that is sure that it does not fail and it looks fast and simple.
