This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Event.srcElement is a proprietary alias (implemented in Internet Explorer) for the standard
Event.target property, which is starting to be supported in some other browsers for web compatibility purposes.
Not part of any specification.
