jQuery Utility Methods

Not seeing where I'm going wrong on this...

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

It's task 1/2 on the jQuery utility methods in Form Validation and Manipulation.

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

Hi Taylor,

I couldn't agree more re their messages.

I am also struggling with this one, have tried all possible permutations I think.

Could you please send me your code that finally resolved this.

Would be much appreciated.

Hi there,

The values are just $(this).val(). The == "" would return if they are blank or not. If you remove the =="" you should be fine.

Your error messages leave a lot to be desired. You do not mention if you want a function call, or just the line requested in the description etc. what is it you exactly want.?? When I type out : var values = $(".required").map(function(){$(this).val();}); The error msg states I have not set "values".. You have to give us a little more to work with as your video really does not show the answer.

revised: after much playing around I finally figured it out...you still need better messages.
