Set focus on input field with jquery in specific table row -

-

i have following html:

<table>   ....   <tr>     ....   </tr>    ....   <tr id="myid">      <....>         <input value="..." />      </....>   </tr>   <tr id="myanotherid">      <....>         <input value="..." />      </....>   </tr> </table>

how can set focus on input field in table row "myid" jquery ? can't set id on input field, because html generated automatically.

use table anchor , find input regardless of value. 

$('table tr#myid').find('input:first').focus()
