How do you receive server-sent event notifications
The EventSource object is used to receive server-sent event notifications. For example, you can receive messages from server as below,
javascript
if (typeof EventSource !== "undefined") {
var source = new EventSource("sse_generator.js");
source.onmessage = function (event) {
document.getElementById("output").innerHTML += event.data + "<br>";
};
}
