onabort() is an event handler invoked when the user aborts the loading of an image (for example, by clicking the Stop button). This event handler is defined by the onAbort attribute of an <IMG> tag. The value of this attribute may be any number of JavaScript statements, separated by semicolons; these statements will be executed only when the user aborts loading for the specified image.
