JQuery change clone inputs to empty

问题

I am trying to clone a class that contains inputs and textareas, and turn their values to nothing.

var current = $(".item").last();

  current.clone().insertAfter( current );
  current.find('input,textarea').val('');

The problem is instead of clearing the cloned objects inputs and textareas, it clears the last class inputs and textareas before that.

回答1:

Your code is modifying the current objects, not the cloned ones. Try something like this:

var current = $(".item").last();

var cloned = current.clone();
cloned.find('input,textarea').val('');
cloned.insertAfter( current );
