requiredValues method in jQuery

The instructions are: Create a method called 'requiredValues' that returns an array of all the values of inputs with the class of 'required'.

Here is my code:

function requiredValues() {
  var reqFields = new Array();
  $("input").each(function () {
    reqFields.push($(".required").val());
  });
  return reqFields;
}

The error message just says there's something wrong with my code. I've been going over it several times and I can't get it to work. Please help!

Thanks in advance.

Instead of iterating over all input fields, just iterate over elements with the class .required. Then, push the value of $(this) into the array.

var someArray = new Array();
$(".classYouNeed").each(function () {
  someArray.push($(this).val());
});

This worked great, thanks!

I see my mistake was not only that I was trying to loop over all the inputs, but that I was selecting the target elements wrong.

Thank you.

$('form.test').on('submit', function(){ var that = $(this), url = that.attr('action'), type = that.attr('method'), data = {};

    that.find('[name]').each(function(index, value){


        var that = $(this),
            name = that.attr('name'),
            value = that.val();

        data[name] = value; 

    });

        $.ajax({
            url:url,
            type:type,
            data:data,
            success:function(output){
            $('#res').html(output).slideDown("slow");

            }

        });

    return false;

//This is the jquery version that will work.. Create a form with the name test or you can change it..... You can modify the code once you keep the structure it will work like a charm.. Note the page will not fefresh when you submit.. just change false at the end to true.
