I am using the input mask jQuery plugin but I am unable to see placeholder text by default but on hover it will be displayed.
$("input[name='birth_year_1']").inputmask("dd/mm/yyyy", {
placeholder: "dd/mm/yyyy"
});
Set the clearMaskOnLostFocus
option
$(document).ready(function(){
$("#date").inputmask("99/99/9999",{ "placeholder": "dd/mm/yyyy", clearMaskOnLostFocus: false});
});
