jQuery addClass only to <td> where the parent <tr> has specific class

so what i try to do is, to add a class to every element, where the parent has a specific class. I tried this: ``` if ($('tr').hasClass('storno')) { $('tr > td').addClass('storno'); } ``` and this is the html example: ``` <table> <tr class="storno"> <td>test</td> <td>test2</td> </tr> <tr> <td>test</td> <td>test2</td> </tr> </table> ``` i tried it also with some other code, but at this point, i dont know i can get it right. Thank you very much in advance
