EventSource: close() method
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
Note: This feature is available in Web Workers.
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
js
close()
Parameters
None.
Return value
None (undefined
).
Examples
js
const button = document.querySelector("button");
const evtSource = new EventSource("sse.php");
button.onclick = () => {
console.log("Connection closed");
evtSource.close();
};
Note: You can find a full example on GitHub — see Simple SSE demo using PHP.
