Remarks

A WebErrorStatus value is returned by Windows.Web.WebError.GetStatus | getStatus, Windows.Networking.WebSocketError.GetStatus | getStatus, and Windows.Networking.BackgroundTransfer.GetStatus | getStatus.

The following example demonstrates how to use WebErrorStatus to display a different error message depending on the type of error. In this example, the WebErrorStatus value is returned by Windows.Networking.WebSocketError.GetStatus | getStatus.



var errorStatus = Windows.Networking.Sockets.WebSocketError.getStatus(error.number);
if (errorStatus === Windows.Web.WebErrorStatus.cannotConnect ||
    errorStatus === Windows.Web.WebErrorStatus.notFound ||
    errorStatus === Windows.Web.WebErrorStatus.requestTimeout) {
    WinJS.log && WinJS.log("Cannot connect to the server");
}
else {
    WinJS.log && WinJS.log("Failed to connect: " + getError(error));
}
