  • 2 document.getElementsByClassName("mtb-ofr")[0].childNodes ? or just .children. – sachleen Commented Jun 22, 2012 at 18:45
  • 2 getElementsByClassName returns an array, you need to select an item of the array before you can drill down any deeper – jackwanders Commented Jun 22, 2012 at 18:45
  • Basically what i want is to replace AAAAA with some other text. – Pooja Desai Commented Jun 22, 2012 at 18:48

Reset to default 2

to change the label's text:

document.getElementsByClassName("mtb-ofr")[0].childNodes[1].nodeValue = 'something';

getElementsByClassName returns an array. You need to first get the element from the NodeList.

document.getElementsByClassName("mtb-ofr")[0].childNodes[1].nodeValue

Use jQuery !

$('label.mtb-ofr').children()

You're done !

And you can filter more by passing parameters to children().

http://api.jquery./children/
