javascript - How to remove control characters from string? -

-

I have a form on my page where the user can write some text and submit it. The text is sent to the server (the REST API at the top of the node. JS) and is saved in DB (Postgrad).

The problem is that some strange characters (control characters) are saved on DB Opportunity - for example the escape control character (^ [] or backspace control character (^ H). Also, because these characters are invisible, so html is sung correctly. However, when I provide XML content for RSS readers, then they (the reader) will control those control characters (this works after removing them) Cause "Perverted XML"

My question is how can I remove those characters on the client level (javascript) or the server level (javascript / node.js) string?

Find me the correct answer here: 

  s.replace (/ [\ X00- \ x1F \ x7F- \ x9F] / g, "");
< / Div>

I had a similar problem, here is the solution that I choose.

I have encoded encryption User (variable_name) using the user String data is encoded and then I have been decoded decoded through encontant (variable) saved

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
