The close() method of the EventSource interface closes the connection, if one is made, and sets the EventSource.readyState attribute to 2 (closed).
Note: If the connection is already closed, the method does nothing.
Syntax
eventSource.close();
Parameters
None.
Return value
Void.
Examples
var button = document.querySelector('button');
var evtSource = new EventSource('sse.php');
button.onclick = function() {
console.log('Connection closed');
evtSource.close();
}
Note: You can find a full example on GitHub — see Simple SSE demo using PHP.
