I am preparing the ranking bar, I have 9 times, though I want the height of the bar at 0 And the times are the longest in 8 I use the value of the option of choosing to manipulate my jquery selector to change the CSS style of the bar. Below is my code.

css: 

  .rating-c .br-widget {height: 60px; Display: Inline; } .teaching-c. BR-Widget A {display: inline; Width: 20px; Height: 60px; Swim left; Background-color: #FFFFFF; Margin: 2px; Text-decoration: None; Font-size: 16px; Font-weight: 400; Line-height: 2.2; Text align: center; Color: # 444444; Border: thin concrete # B6B6B6; } .rating-c .br-widget a.br- active, .rating-c .br-widget a.br-selected {background color: # 59a6d6; White color; }

html: 

  & lt; Div class = "rating-c" & gt; & Lt; Label class = "rating label" & gt; & Lt; Select ID = "Rating-C" name = "Rating" & gt; & Lt; Option value = "" & gt; & Lt; / Options & gt; & Lt; Option value = "1" & gt; 4 & lt; / Options & gt; & Lt; Option value = "2" & gt; 3 & lt; / Options & gt; & Lt; Option value = "3" & gt; 2 & lt; / Options & gt; & Lt; Option value = "4" & gt; 1 & lt; / Options & gt; & Lt; Option value = "5" & gt; 0 & lt; / Options & gt; & Lt; Option value = "6" & gt; 1 & lt; / Options & gt; & Lt; Option value = "7" & gt; 2 & lt; / Options & gt; & Lt; Option value = "8" & gt; 3 & lt; / Options & gt; & Lt; Option value = "9" & gt; 4 & lt; / Options & gt; & Lt; / Select & gt; Price & lt; / Labels & gt; & Lt; / Div & gt; Javascript:  
  $ ('Rating-c. BR-widget one selection [name = rating]'). Each (function ($ (this) .attr ("value") === "2") {$ ("rating-c"). CSS ("height", "55px");} ($ (This) atter ("value") === "3") {$ ("rating-c. BR-widget A"). CSS ("height", "50px");}});  
 
 It does not work, anyone can help Thanks. Please help

Which @ stirlingteacher said, use it, use it this .value and parseInt ... 

  if (parseInt (this.value) === 2) {$ ("some"). CSS ("key", "value"); };

First, parseInt converts the value into a number, which means your special comparison is more important.

Second, we use the value property, this.value and not the attribute $ (this) .val () Retrieves that, instead of the value attribute, which you were previously doing.

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. ...
