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?
