close event is fired when a connection with a WebSocket is closed.

冒泡	No
可取消	No
接口	CloseEvent
事件处理程序特性	onclose

范例

You might want to know when the connection has been closed so that you can update the UI or, perhaps, save data about the closed connection. Given that you have a variable called exampleSocket that refers to an opened WebSocket , this handler would handle the situation where the socket has been closed.

exampleSocket.addEventListener('close', (event) => {
  console.log('The connection has been closed successfully.');
)};
					

You can perform the same actions using the event handler property, like this:

exampleSocket.onclose = function (event) {
  console.log('The connection has been closed successfully.');
};
