Question

This is working fine in firefox but only closes the first page and then breaks in IE8. Firebug in IE8 says that x.item(o) is null. I can’t figure out why this works in firefox but not IE. Thanks for any help.

pager(x=document.getElementsByName("pg1"));

function pager( x ) {
    var curr = document.getElementById('showing');
    $(curr).fadeOut('fast');
    curr.id = 'hide';
    $(x).fadeIn('slow');
    x.item(0).id ='showing';
}

Answer 1

if(x.item(0).id = NULL )

That’s an assignment. You wanted == for comparison.

(What’s NULL in capital letters? An element’s id property won’t be null; if it’s not set, it’ll be an empty string.)

It seems to me you’d be better off using jQuery’s toggle method.
