संभव डुप्लिकेट:

मैं जावास्क्रिप्ट में कुछ ऑब्जेक्ट्स का निर्माण कर रहा हूं और उन ऑब्जेक्ट को एक सरणी में डाल रहा हूं, मैं उस कुंजी को संचित कर रहा हूं जिसे मैं एक चर में उपयोग करना चाहता हूं, फिर बनाना मेरी ऑब्जेक्ट्स समान हैं: 

  var key = "happyCount"; MyArray.push ({key: someValueArray});

लेकिन जब मैं हर ऑब्जेक्ट के लिए मेरे ऑरेरे ऑरेजेस की जांच करने की कोशिश करता हूं तो वह चर के मान के बजाय कुंजी "key" है क्या कोई वैरिएबल से चाबी का मूल्य सेट करने का कोई तरीका है?

"post-text" itemprop = "text">

आपको पहले ऑब्जेक्ट बनाने की ज़रूरत है, फिर इसे सेट करने के लिए [] का उपयोग करें। 

  var key = "happyCount"; Var obj = {}; Obj [key] = someValueArray; myArray.push (obj);

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. ...
