Where is the HTML code with the element you're trying to get? — RichardAE, Mar 06 '15 at 09:23
what is dateDisplay which control's id ? provide html please — Arunprasanth K V, Mar 06 '15 at 09:23
`getElementById` just returns a single element and not a set of elements like `getElementByClassname`, so the [0] is unnecessary here — empiric, Mar 06 '15 at 09:25

Remove [0] from your document.getElementById('dateDisplay')[0];

document.getElementById does not return an array, so there is no point in having an index pointer.

If that was the only issue, the error message would be different. The other problem seems to be that the element is not found. – Felix Kling Mar 06 '15 at 09:28
