When the server reboots, the Web Socket connection is closed, so the JavaScript onclose
event is triggered. Here’s an example that tries to reconnect every five seconds.
function start(websocketServerLocation){
ws = new WebSocket(websocketServerLocation);
ws.onmessage = function(evt) { alert('message received'); };
ws.onclose = function(){
// Try to reconnect in 5 seconds
setTimeout(function(){start(websocketServerLocation)}, 5000);
};
}
