In Mozilla it seems to be returning null instead (embarassingly, IE 6 gets it right). I have changed my test from 'if ( "" == id )' to 'if ( ! ( id > "" ) )' to get around it, so it isn't a show-stopper, but it does seem to be a bug. Reproducible: Always Steps to Reproduce: 1. var id = currentElement.getAttribute ( "id" ); 2. (where the current element does not, in fact, have an id) 3. if ( "" == id ) Actual Results: Mozilla does not execute the body of the if statement. Expected Results: Mozilla executes the body of the if statement.
