add class to the children if parent has a "translate" class and remove "translate" class of the parent after

have any idea for this?

example code:

&开发者_C百科lt;td>
  <div class="translate">
    <p><span>Hello world</span></p>
    <p><strong>hellow <span>there</span></strong</p>
  </div>
</td>

the output should be

<td>
  <div class="">
    <pclass="translate"><span class="translate">Hello world</span></p>
    <p class="translate"><strong class="translate">hellow <span class="translate">there</span></strong</p>
  </div>
</td>

---

$(".translate").removeClass("translate").children().addClass("translate");

---

$("p.translate").removeClass("translate").children().addClass("whatever");
