• 在Google Chrome中使用Web Sockets | 3秒 (3seconds.cn)

  tags: google, chrome, web sockets

  • 从Google Chrome的developer channel释放的4.0.249.0版本开始，Web Sockets已经可用并默认开启了。Web Sockets是“网络的TCP”，它是Web Applications 1.0中下一代网络应用程序双向通信技术标准的一部分
  • 与XMLHttpRequest截然不同的的是，Web Sockets在你的浏览器里面提供一个真正的双向沟通渠道，一旦得到Web Socket连接，你就能通过直接调用send()方法从浏览器发送数据到服务器，并且使用onmessage的这个事件处理句柄接收数据
  • if ("WebSocket" in window) {
    var ws = new WebSocket("ws://example.com/service");
    ws.onopen = function() {
    // Web Socket is connected. You can send data by send() method.
    ws.send("message to send"); ....
    };
    ws.onmessage = function (evt) { var received_msg = evt.data; ... };
    ws.onclose = function() { // websocket is closed. };
    } else {
    // the browser doesn't support WebSocket.
    }
