问题 Is there a tool out there to measure the actual Render time of an element(s) on a page? I don't mean download time of the resources, but the actual time the browser took to render something. I know that this time would vary based on factors on the client machine, but would still be very handy in knowing what the rendering engine takes a while to load. I would imagine this should be a useful utility since web apps are becoming pretty client heavy now. Any thoughts? 回答1: I've been using this

问题 I just found that when I click browser back button on any ASP .NET MVC page nothing happens and page is not going be updated. And only if you click F5 it will be updated only. The main problem that I do some changes of DOM of the page i.e. add table rows select radio-buttons and etc and when I go back to page by hitting browser back button I have see no changes. How it can be resolved for ASP .NET MVC 5? Thank for any clue... P.S. I have read http://forums.asp.net/t/1304752.aspx?how+to

问题 I can't invoke a basic wcf web method in the browser even with <ServiceMetadata httpGetEnabled="True"/> in the config file. For the source, code, it's very basic: For the interface: [ServiceContract] public interface IService1 { [OperationContract] [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)] string GetData(); [OperationContract] CompositeType GetDataUsingDataContract(CompositeType composite); // TODO: ajoutez vos opérations de

问题 Is anyone aware of a definitive list of areas of missing support for ECMAScript/JavaScript in the major browsers (I'm talking IE7+, Firefox, Chrome, Safari and Opera). Obviously we do feature detection in our code, but I'd like a list of features that we need to perform detection on ideally. 回答1: Some commonly referenced sources are Great compatibility tables at QuirksMode. Some of them are being updated recently. Kangax sums up ES5 support very well. Microsoft released reports of IE

问题 I need to live stream from a decklink card to a browser. I also must be able to do it with a very poor network link (128kbits/s...), so I need to be able to stream at a very low fps (1 fps is fine) and a very low image quality. At the moment I'm using GStreamer to get the video from the card, to transcode it to MJPEG, and to stream it with TCP. This part is perfectly working, but now I need to tube this tcp stream to an HTTP stream. I can do this with VLC and it works well at a "normal"

问题 Is there a standard (accepted/easy/performant) way to determine how fast a client machine renders javascript? When I'm running web apps (videos, etc) on my other tabs my JS animations slow to a crawl. If I could detect slowness from my JS, I would use simpler animations to provide a better user experience. Update: Removing animations for everyone is not the answer. I am talking about the simplest of animations which will stutter depending on browser / computer. If I could detect the level of

问题 Firefox has this annoying behavior that it let's the user drag and drop any image element by default. How can I cleanly disable this default behavior with jQuery? 回答1: The following will do it in Firefox 3 and later: $(document).on("dragstart", function() { return false; }); If you would prefer not to disable all drags (e.g. you may wish to still allow users to drag links to their link toolbar), you could make sure only <img> element drags are prevented: $(document).on("dragstart", function(e

问题 The webbrowser library provides a convenient way to launch a URL with a browser window through the webbrowser.open() method. Numerous browser types are available, but there does not appear to be an explicit way to launch Internet Explorer when running python on windows. WindowsDefault only works if Internet Explorer is set as the default browser, which is not an assumption I can make. Is there a way to explicitly launch a URL into Internet Explorer without reverting to windows API calls? 回答1:
