window.event.srcElement gets the event source object_javascript skills

<p>One advantage is that if I want certain objects in the body (or other elements) to respond to events, I don’t have to write them one by one. Just write one on the outer layer and then check whether event.srcElement.tagName or other properties are what you want to decide whether to respond to the event. But it seems that event.srcElement does not work in ff </p> <p>For example</p> <p> <input value="input"> <span>span</span></p> <div>div</div> <p>The event object refers to the currently triggered event object, and window.event.srcElement refers to the object that triggered the event. For example, if you set document.onclick = myfunc; then all page click events are handled by myfunc. In the myfunc function, you can write vSrc = window.event.srcElement to know where the user clicked and handle it accordingly. Find an HTML file and add this paragraph: </p> <p> <textarea rows="10" cols="90">

Just try it and you will know.

void(0) is a function that does nothing.
