Help - Build an Interactive Website > jQuery Plugins > Simple Email Validation Plugin (4/4)

Hey guys, I'm stuck at code challenge "Simple Email Validation Plugin" 4/4

The error msg displayed when I ask to 'check my work': "Bummer! null"

Challenge: "In the "success" function add the class of "valid" to the textarea that's had a the "keyup" event triggered"

This is what I'm trying:

  var isValid = $("input").validEmail(); 

  $("textarea").validEmail({on:"keyup", success:function(){
      $this.next().removeClass("error").addClass("valid");}, failure:function(){ 
        $this.next().removeClass("valid").addClass("error");}
  });

  requiredFilledIn();

Any help is welcome ^^

Hi Andrew,

I tried and a new msg appeared: "Bummer! Try selecting 'this' in the success method and using the 'addClass' method"

So I tried some stuff and ended up with this:

var isValid = $("input").validEmail(); 

  $("textarea").validEmail({on:"keyup", success:function(){
      $(this).addClass("valid");}, failure:function(){ 
        $(this).next().removeClass("valid").addClass("error");}
  });

  requiredFilledIn();

That worked ^^

Thnx for the help!

I'm not sure how the .next() is supposed to be used. In the video lesson we use it apply the .addClass() and .removeClass() methods, but here you were able to pass the quiz by ommitting the .next() method?

It could be just me, but are addClass("valid"); and addClass("error"); not supposed to have the closing brackets at the end?

The curly? They have...

"success:function(){ $this.next().removeClass("error").addClass("valid");}"

"failure:function(){ $this.next().removeClass("valid").addClass("error");}"
