if div has class remove the class and add it to its parent

Question

I have

<div class="image-mask">
    <img class="alignright" src="image.png" />
</div>

and I would like to use jQuery to move the class from the image to the parent div.

Thanks very much!!

Answer 1

这应该工作：

 $('.alignright').removeClass('alignright').parent().addClass('alignright');
