它说
返回浏览器的在线状态.该属性返回一个布尔值,其中true表示在线,false表示离线.只要浏览器连接到网络的能力发生变化,该属性就会发送更新.当用户跟踪链接或脚本请求远程页面时,会发生更新.例如,当用户在失去互联网连接后立即点击链接时,该属性应返回false.

如何获得 10
我需要编写一个可以在图标上显示徽章编号的应用程序.
我能够收到推送通知,徽章编号也显示为5.
但是,当应用程序尚未启动时收到第二个推送通知时,徽章仍会显示5.
它不应该是10?
我试图在cygwin中安装QT5并成功.我也正在Cygwin/X为设计师提供Xorg菜单.
但我找不到QT5的qmake.exe.我只在cygwin选择包窗口中获得以下文件
并且还表示mingw64-xxxx-qt4-qmake.exe不qmake.exe
不幸的是,我无法牺牲cygwin并进行Windows分发.我应该从源代码构建Qt5吗?
我需要从C#windows窗体代码连接基于Node.js的WebSocket

using SuperSocket.SocketBase.Logging;
using SuperWebSocket;
using SuperWebSocket.SubProtocol;
using WebSocket4Net;

WebSocket webSocketClient = new WebSocket("ws://localhost:8080/");
webSocketClient.Error += new EventHandler<SuperSocket.ClientEngine.ErrorEventArgs>(webSocketClient_Error);
webSocketClient.AllowUnstrustedCertificate = true;
webSocketClient.Opened += new EventHandler(webSocketClient_Opened);
webSocketClient.Closed += new EventHandler(webSocketClient_Closed);
webSocketClient.MessageReceived += new EventHandler<MessageReceivedEventArgs>(webSocketClient_MessageReceived);
webSocketClient.Open();
