internet explorer - IE8 and JQuery's trim()

Question

I am making use of trim() like so:

if($('#group_field').val().trim()!=''){

Where group_field is an input element of type text. This works in Firefox but when I try it on IE8 it gives me this error:

Message: Object doesn't support this property or method

When I remove the trim(), it works fine on IE8. I thought the way I am using trim() is correct?

Thanks all for any help

Try this instead:

if($.trim($('#group_field').val()) != ''){
