javascript - Instability when loading JQuery dynamically in Firefox -

-

No need to declare a function where the library Jyoki me depending on the situation and some other scripts, warning As a .js script which is a class of the same name, I tested that functionality in Google Chrome and Mozilla Firefox. Firstly the script is always loaded correctly before the implementation of class function / class warning (), even though the scripts in Firefox are loaded astatically. In other words, when the function warnings are executed, some time is not jQuery Are still ready, this page is needed to refresh.

To further clarify, the value given by the Firefox Error Console is: 

  ReferenceError: jQuery is not defined

Below Code: 

  if (typeof (warning) === 'undefined') {var scripts = [DIR_JS_LIB + 'lib / jQuery / jQuery. min.js ', DIR_JS_LIB +' lib / jQuery / jQuery-ui / jQuery-ui.min.js ', DIR_JS_LIB +' scripts / COMPONENTES / dialogues / AcaoJanela.js ', DIR_JS_LIB +' scripts / COMPONENTES / dialogues / Botao. JS ', DIAR_JS_LB +' Scripts / Components / Dialogs / Dialogs JS ', DIAR_JS_LB +' script / component / dialog / alert.js']; (Var i = 0; i & lt; scripts.length; i ++) {include (script [i]); }} Window.onload = function () {warning (window.mensagem, window.titulo, window.botoes); } Function (file_path) {var j = document.createElement ("script"); J.src = file_path; Document.getElementsByTagName ('head') [0] .appendChild (j); }

Assure a cross-browser solution to load and prepare dependent JS libraries Well known problem Your contains script is not found well What works best for me is checking the status of loaded files, and chaining calls as callback Does. In your case it will look like the following: 

  functions include (file name, callback) {var fileref = document.createElement ('script'); Fileref.setAttribute ("Type", "Text / JavaScript"); Fileref.setAttribute ("src", file name); If (fileref.readyState) {fileref.onreadystatechange = function () {/ * IE * / if (fileref.readyState == "load" || fileref.readyState == "complete") {fileref.onreadystatechange = null; call back(); }}} {Fileref.onload = function () {/ * other browser * / callback (); }} // to try to find the head, otherwise document default if Element (typeof fileref! = "Undefined") (document.getElementsByTagName ( "head") [0] || document.documentElement) .appendChild (fileref) } if (typeof (warnings) === 'undefined') {var script = [DIR_JS_LIB + 'lib / jQuery / jquery.min.js', DIR_JS_LIB +' lib / jQuery / jQuery-ui / jQuery-ui.min. Js ', dir_js_lb +' scripts / components / dialogs / plans.js ', dir_js_lib +' script / component / dialog / boto. JS ', DIR_JS_LB +' script / component / dialog / dialog.js', DIRE_JS_LB + 'script / components / dialog / alert.js']; Includes (Script [0], function () {include script ([1], function () {include script ([2], function () {include (script [3], function () {} (includes scripts [4], function (() (script [5], function () {alert (window. Mensgem, Vindotitulo, Vindokbots);})}});})}}}}}); });}

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. ...
