Question

I am trying to add a class to textarea on keyup event . The event is firing but the class is not getting added . Here I am trying to add the class if it doesn’t exist to that textarea instance

  $("textarea").live("keyup", function() {
    $("this[class='']").addClass("modified");
      });

During submit , I am using the below code to disable the ones which doesn’t have class modified . But this is not submitting any textareas . So looks like no class is being added in the above code .

$("textarea:not(.modified)").attr("disabled", "disabled");

Could some one help me what the problem with this code?

Thanks

Regards

Answer 1

It should be

$("textarea").live("keyup", function(e) {
  $(e.target).addClass("modified");
});

The class will not be added if it is present already.
