我有这个简单的 WebSocket 问题
<!DOCTYPE html>
<meta charset="utf-8" />
<title>WebSocket Test</title>
<script language="javascript" type="text/javascript">
var wsUri = "ws://echo.websocket.org/";
var output;
function init() {
output = document.getElementById("output");
testWebSocket();
}
function testWebSocket() {
websocket = new WebSocket(wsUri);
websocket.onopen = function (evt) {
onOpen(evt)
};
websocket.onclose = function (evt) {
onClose(evt)
};
websocket.onmessage = function (evt) {
onMessage(evt)
};
websocket.onerror = function (evt) {
onError(evt)
};
}
function onOpen(evt) {
writeToScreen("CONNECTED");
doSend("WebSocket rocks");
}
function onClose(evt) {
writeToScreen("DISCONNECTED");
}
function onMessage(evt) {
writeToScreen('<span style="color: blue;">RESPONSE: ' + evt.data + '</span>');
websocket.close();
}
function onError(evt) {
writeToScreen('<span style="color: red;">ERROR:</span> ' + evt.data);
}
function doSend(message) {
writeToScreen("SENT: " + message);
websocket.send(message);
}
function writeToScreen(message) {
var pre = document.createElement("p");
pre.style.wordWrap = "break-word";
pre.innerHTML = message;
output.appendChild(pre);
}
window.addEventListener("load", init, false);
</script>
<h2>WebSocket Test</h2>
<div id="output"></div>
</html>
我的问题是我如何才能访问网络套接字关闭代码?
如本网站所述
https://developer.mozilla.org/en-US/docs/WebSockets/WebSockets_reference/CloseEvent
1001 CLOSE_GOING_AWAY
1000 CLOSE_NORMAL
1005 CLOSE_NO_STATUS
1006 CLOSE_ABNORMAL
现在这是我的 onclose 函数
function onClose(evt) { writeToScreen("DISCONNECTED"); }
我已将警报设为 alert(evt),但我没有收到任何关闭代码。
有人可以帮忙吗
最佳答案
试试这个:
function onClose(event)
{
alert('Onclose called' + event);
alert('code is' + event.code);
alert('reason is ' + event.reason);
alert('wasClean is' + event.wasClean);
}
