Code Challenge: jQuery Utility Methods

Struggling with this problem altogether:

Call 'map' on the inputs with the class 'required' and return each of their values and store it in a variable named 'values'. Any insight on where to start?

var values = $(".required").map(function(){ return $(this).val() ==""; })

I have tried this but it says:"The values aren't what we're expecting. Please try again."

Remove the =="". The =="" is testing the values in each required field with the empty string, all we want is the values themselves. The .val() method returns the value in an input. That's all that is needed for this step.

Here's it split in to a more logical order:

  1. Create a variable called values
  2. Using jQuery select .required
  3. Call map on it
  4. In the map call write an anonymous function and return $(this).val() i.e. the value of the required field.

Hope this helps. If not paste in where you get to and we'll take it from there.

I don't understand what I'm doing wrong. I followed your directions and got this:

var values = $(".required").map(function(){$(this).val()});

And when I submit, it says "Bummer! The values aren't what we're expecting. Please try again."

Oops nevermind. I got it. I wasn't returning anything before.
