using getNextSibling in ie

<input type="button" value="View" onClick="alert(this.getNextSibling)" />
<table ...>
......


I have a button which I am trying to toggle the display of a table. The ids are all dynamic so I am trying to use getNextSibling with no luck. The above alert returns an 'undefined'. I have fixed this by wrapping it all by a div and finding the parentNode but I was wondering why the above would not work.

If you change that to [object Element].nextSibling you'll probably find it working better.

much better...Thanks.
