<Html> <body> <p> one advantage is that I want the body (or other elements) some object response events do not need to be written one by one on the outer layer and then check the event. srcElement. whether the tagName or other attributes are what you want to determine whether to respond to the event. but it seems like event. srcElement does not work in ff </p> <p> for example </p> <input value = "input"> span </p> <p> p </p>/ p> <p> event object refers to the event object Currently triggered, window. event. srcElement refers to the object that triggers the event. For example, you set document. onclick = myfunc; at this time, all the page Click events are handed over to myfunc for processing. In the myfunc function, you can write vSrc = window. event. srcElement, know where the user clicked, and perform corresponding processing. Add the following section to an HTML file: </p> <textarea rows = "10" cols = "90"> <script syntax Ange = "javascript"> document. onclick = myfunc; function myfunc () {alert (window. event. srcElement. tagName);} script </textarea> <script Ange = "javascript"> document. onclick = myfunc; function myfunc () {alert (window. event. srcElement. tagName);} script </p> <p>. Void (0) is a function that does nothing. </P> </body>
