getElementById method for W3C DOM-incapable browsers.
* For these browsers it returns always null. You do not have
* to detect the getElementById elsewhere in a script anymore.
*
* You should always check, if the returned value is not null to
* prevent script errors; getElementById returns null in
* W3C DOM-capable browsers as well, if there is no match for the given id in
* the document tree.
*
* Usage:
*
* var elem = document.getElementById(id);
* if (elem) {
* // process elem
* }

/**
* Binds an event handler function to a given node, so that the function executes
* when an event of the particular, given type arrives at the node either as event
* target or during event propagation. Existing events, either defined as a tag
* attribute or binded dynamically, are not affected.
*
* Note: If this has to work in IE/Mac with existing events as tag attributes
* the call to bind a new event has to follow the target node in the source
* code.
*
* @param target the node to which the event will be binded
* @param eventType a string of one event type (without the "on" prefix)
* known to the browser's object model
* @param listenerFunction a reference to the function to execute, when the node
* hears the event type
* @param useCapture a Boolean value. If true, the node listens
* for the event type only while the event propagates
* toward the target node. If false, the
* node listens only when the event bubbles outward from
* the event target. The typical setting of this parameter
* is false and if omitted, it falls back to
* that value.
