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.
