jQuery non-text input validation

I have a Bootstrap table I obtained from Tutorial Republic. It goes as such:

When you click “+ Add New” and try to add an empty record (leaving text fields empty), you are prevented from doing so and the textbox’s border turns red.

However, when I add in a date field,

var row = '<tr>' +
        '<td><input type="text" class="form-control" name="name" id="name"></td>' +
        '<td><input type="text" class="form-control" name="department" id="department"></td>' +     
        '<td><input type="text" class="form-control" name="phone" id="phone"></td>' +
        '<td><input type="date" class="form-control" name="date" id="date"></td>' +
        '<td>' + actions + '</td>' +
    '</tr>';

I am still seemingly prevented from adding a record but the border of the date box does not turn red. The same thing happens for <select> dropdown menus.

I am looking at this bit here, the line .find('input[type="text"]'):

// Add row on add button click
$(document).on("click", ".add", function(){
    var empty = false;
    var input = $(this).parents("tr").find('input[type="text"]');
    input.each(function(){
        if(!$(this).val()){
            $(this).addClass("error");
            empty = true;
        } else{
            $(this).removeClass("error");
        }
    });
    $(this).parents("tr").find(".error").first().focus();
    if(!empty){
        input.each(function(){
            $(this).parent("td").html($(this).val());
        });         
        $(this).parents("tr").find(".add, .edit").toggle();
        $(".add-new").removeAttr("disabled");
    }   

but I am afraid that is the extent of my abilities as a jQuery first-timer haha!

How do you modify the code to have both text type and non-text type inputs turn red their borders?

Thank you!

You need to include the [type=”date”] control: .find('input[type="text"], input[type="date"])
