I have software that uses html5 and websockets and allows me to create a webpage that allows users to connect to a windows server using remote desktop protocol in their web browser, can I use modernizer to make this site compatible with ie8? Their are pages that I have to store on the windows server and on my web hosting account that are needed for this app. Basically, can modernizer work on a
我有使用html5和websockets的软件，并允许我创建一个网页，允许用户在他们的网页浏览器中使用远程桌面协议连接到Windows服务器，我可以使用modernizer使本站与ie8兼容吗？ 他们是我必须存储在Windows服务器和我的网络托管帐户所需的这个应用程序的页面。 基本上，modernizer可以在一个已经在html5中构建的web应用程序上工作吗？ 如果是这样，我该怎么做？ 我们使用的软件是Ericom AccessNow这是一个简短的描述，“Ericom Acce
I currently have a Qt-based GUI application that simply provides a graphical dashboard (guages, graphs, and such) displaying real-time data provided by another application via a TCP connection. For architectural and security reasons, I have been told that my TCP connection is no longer allowed, and that an HTTPS websocket will be my only conduit. It was suggested that I convert my app to a weba
我目前有一个基于Qt的GUI应用程序，它只是简单地提供一个图形仪表板（参数，图表等），显示由另一个应用程序通过TCP连接提供的实时数据。 由于架构和安全原因，我被告知我的TCP连接不再被允许，并且HTTPS websocket将成为我唯一的管道。 有人建议我将应用程序转换为使用HTML5和Javascript的web应用程序。 但是，我不是一个网络程序员，但可以认为这是学习新技术的机会。 在作出决定之前，我想先了解一下风景。 所以，我认为
I have read many posts on SO and the web regarding the keywords in my question title and learned a lot from them. Some of the questions I read are related to specific implementation challenges while others focus on general concepts. I just want to make sure I understood all of the concepts and the reasoning why technology X was invented over technology Y and so on. So here goes: Http Polling
我在SO和网上阅读了很多关于我的问题标题中关键字的帖子，并从中学到了很多。 我读到的一些问题与具体的实施挑战有关，而另一些则关注一般概念。 我只想确保我理解了为什么技术X是相对于技术Y而言发明的所有概念和理由。 所以在这里： Http轮询：基本上是AJAX，使用XmlHttpRequest。 Http Long Polling： AJAX，但服务器保留响应，除非服务器有更新，只要服务器有更新，它就发送它，然后客户端可以发送另一个请求。 缺点
I'm trying to connect two peers using peerJS. I am pretty much just following through their "Getting Started" but I am still struggling. Below is the code that I have gotten so far. <body> <script src="http://cdn.peerjs.com/0.3/peer.min.js"></script> <script> var conn; var peer = new Peer({key: 'lwjd5qra8257b9'}); peer.on('open', function(id){
我正尝试使用peerJS连接两个对等端。 我几乎完成了他们的“入门”，但我仍在挣扎。 以下是我迄今获得的代码。 <body> <script src="http://cdn.peerjs.com/0.3/peer.min.js"></script> <script> var conn; var peer = new Peer({key: 'lwjd5qra8257b9'}); peer.on('open', function(id){ console.log('My peer ID is:' + id); document.getElementById('peerIdDisplay').in
I want to accomplish something similar to what photoshop.com has and this site here: http://mrdoob.com/projects/chromeexperiments/google_gravity/ Does anyone know how to do this with javascript (preferably jquery) ? 一个jPhysics演示可以在http://www.inf.ufrgs.br/~rcpinto/physics/上在线找到，并从http：//plugins.jquery.com/project/jphysics或Google下载。 .google.com / p / jqueryphysics / I think
我想完成类似于photoshop.com和此网站的功能：http://mrdoob.com/projects/chromeexperiments/google_gravity/ 有谁知道如何用JavaScript（最好是jQuery）来做到这一点？ 一个jPhysics演示可以在http://www.inf.ufrgs.br/~rcpinto/physics/上在线找到，并从http：//plugins.jquery.com/project/jphysics或Google下载。 .google.com / p / jqueryphysics / 我认为谷歌的例子使用Box2Djs。 我已经使用box2d python和它的伟大
Looking through the dom.js source from the Closure library I found this (in goog.dom.getElementsByTagNameAndClass_ ): if (opt_class) { var arrayLike = {}; var len = 0; for (var i = 0, el; el = els[i]; i++) { var className = el.className; // Check if className has a split function since SVG className does not. if (typeof className.split == 'function' && goog.array.contains(cla
通过Closure库查看dom.js源代码，我发现了这个（在goog.dom.getElementsByTagNameAndClass_ ）： if (opt_class) { var arrayLike = {}; var len = 0; for (var i = 0, el; el = els[i]; i++) { var className = el.className; // Check if className has a split function since SVG className does not. if (typeof className.split == 'function' && goog.array.contains(className.split(' '), opt_clas
there is a dropdown with 5 options. Currently,option 2 is selected.The user selects option 4 now.The onchange event gets fired which is caught in a JS function listening for onchange on the select. In the JS function, I can check easily the index of the option selected by the user using the selectedIndex property.However, I want to also know what was the original value that the user changed it
有5个选项的下拉菜单。 目前，选项2被选中。用户现在选择选项4. onchange事件被触发，这被捕获在一个JS函数中，在select上侦听onchange。 在JS函数中，我可以轻松地检查用户使用selectedIndex属性选择的选项的索引。但是，我也想知道用户将其改为的原始值是什么。 在这种情况下是否存在一个基本上保留原始值的属性，即选项2。 就像我把一个概念放在一起 - 可能有更好的方法来做到这一点： var vals = []; document.getEl
