[Htmlunit-user] Re: JavaScript question

[Marc G. <mgu...@ya...>]

Robert,

Your js code was correct, the interpretation by htmlunit is wrong and it's not IE specific, it's standard: 
getElementsByTagName should return a NodeList and NodeList should have a method item(int):

Marc.

PS: you can write your changed js code in one line
ssnTableRows[i].getElementsByTagName("td")[1].style.backgroundColor="white";
