CSS :last-child selector in javascript? -

i looking select last td in each row , using css selector right .table td:last-child doesnt work in ie there way can select through javascript (without framework) ie? apply css styles.

var rows = document.getelementbyid('tester').rows;  for(var = 0, len = rows.length; < len; i++) {     rows[ ].lastchild.style.background = 'orange'; }

edit: if you'll running in browsers, may safer this:

var rows = document.getelementbyid('tester').rows;  for(var = 0, len = rows.length; < len; i++) {     rows[ ].cells[ rows[ ].cells.length - 1 ].style.background = 'orange'; } 

example: http://jsfiddle.net/jsyyr/2/

this because browsers insert text node if there's space between last </td> , closing </tr>. such, lastchild wouldn't work.
