jQuery Utility Method Quiz

Hi Guys,

I'm kind of stuck in the first question

Call 'map' on the inputs with the class 'required' and return each of their values and store it in a variable named 'values'.

This is the code I'm using 

var $required = $(".required");
var values = $required.map(function(){ 
  return $(this).val() == "";
}); 
return $.inArray(true, values) != -1;

But I keep getting the error

Bummer! You haven't set the variable 'values'

Any ideas?

Thanks Nick!

Gregory, I tried the same code as you before but that's checking for empty values and not all values

The actual answer for 1 of 2 was

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

And the 2 of 2 was adding 

$.inArray("Andrew", values);

This line needs changing return $.inArray(true, values) != -1;

Only $.inArray(true, values); is required. You can't use return outside a function. So a syntax error occurs and the script isn't parsed correctly and cannot see values.

Thanks Andrew!

Now if I change the code to this

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

I even tried changin to this

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

But now I get 'The values aren't what we're expecting. Please try again.'

Your talking about task 1 of 2 correct?. If that's the case line 3 (your return) .val call doesn't need equals to blank. You just want it to store the value.

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

The answer is 

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