Note: AddEventListener () is a standard method of binding event listener functions, supported by the publisher, Chrome, FireFox, Opera, Safari, This function is supported by IE9.0 and above, but IE8.0 and the following versions do not support this method, and it uses attachevent () to bind the event listener function. Therefore, this method of binding an event must handle browser compatibility issues.
