Jquery Help Needed Whats Wrong with this Code?

Create a method called 'containsBlanks' that returns true if any inputs with class 'required' has an empty string in, false if not.

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

Hi Steve,

You didn't mention if you were having a syntax error or logic error but I suspect you may be having both.

If you take a look at this line:

blanks.push($(this).val()) != "");

You have an extra right parenthesis. Also, I don't see a closing brace for the containsBlanks function but you may have left that off when pasting.

You also may have a logic error.

It looks like you're trying to push a true value onto the array if the field isn't empty. I would recommend that you push a true value onto the array if it is an empty field.

A true entry in the blanks array should indicate that the field was empty.

Let me know if you need more clarification.
