Help With Checking Values Task jQuery

Well first you have to call the "return" method.

try this at the end of the "containsBlank" function:

return $.inArray(true, blanks) != -1;

Hi Gareth,

Just like William says to you need to use the return keyword at the end of the function.

You can use something like inArray to do it.

Let us know if you have any more issues.

Hi William/Andrew,

Thank you for the help, I haven't come across the inArray method before. O.k. so I have used the code that William suggested but now I get a "It looks like Task 1 is no longer passing" error. Any ideas why that would be? My full code is:

function isValidEmail(email) {
  return email.indexOf("@") != -1;
}
var $required = $('.required');

function requiredValues() {
  var $values = new Array();
  $required.each(function() {
    $values.push($(this).val());
  });
  return $values;
}

function containsBlanks() {
  var blanks = new Array();
  $required.each(function() {
   blanks.push($(this).val() == ""); 
  }
  return $.inArray(true, blanks) != -1;               
}

Your right w.r.t. inArray. I go in to inArray in a later video.

I checked in the video and at this point I showed you how to, instead of the indexOf for the array, use a sort().pop() strategy.

You're missing a ); in the end of the each.

$required.each(function() { blanks.push($(this).val() == ""); }

And that should pass :)

Hi Andrew, yes that worked a treat thank you.

I tried to work through the example and use a sort().pop() strategy but I couldn't figure out how to return true or false depending on whether there were blanks. Could you show an example with this so that I have both methods?

Thank you for all your help ;-)

Hi Gareth,

When you use the keyword return the result of the following expression is returned.

return blanks;

Would return the array. e.g. [true, true, false]

return blanks.sort();

Would return an array with false_s at the beginning and _true_s. e.g. _[false, true, true]

return blanks.sort().pop();

Would pop off the last value at the end. If there are true_s _true would be returned.

Regards Andrew

Js is kind of a dead end to me. I wouldn't do it without the forum D:
