Function Document.getElementById

Returns the Element that has an ID attribute with the given value. If no such element exists, this returns null. If more than one element has an ID attribute with that value, what is returned is undefined. The DOM implementation is expected to use the attribute Attr.isId to determine if an attribute is of type ID.

Prototype


DOMImplementation.Element!DOMString getElementById(
								

  DOMString elementId
								

);

Note

Attributes with the name "ID" or "id" are not of type ID unless so defined.
