问题 I want to include a few "bells and whistles" features on a site I'm currently developing, but I don't want to bog down the entire machine for my users. Is there a way I can test to see if the current browser is GPU accelerated? I could just check against UserAgents, but I've always heard it's not accurate enough to trust. I guess I could build a canvas element, make quite a few drawing calls, and time them? Anything under a certain threshold I could consider good enough for my superfluous

问题 Surfing the MDC docs here, I've noticed there are quite a few versions of javascript (1.6 to 1.8.5). I was wondering: Is there any online reference for Browser / Javascript version supported ? Is there any practical application for the use of different javascript versions ? According to MDC you need to do something like this to use them: <script type="application/javascript;version=1.7"/> Which I haven't seen in any website IIRC. Thanks! 回答1: 1) Yes, on Wikipedia is a nice list: http://en

问题 I have a script which if helpful to people answering questions, is using kivy. I want to have it show a iframe kind of thing right into it when run, instead of opening the browser. For example something like this: def browser(): url = "google.com" iframe(url) browser() Obviously this wouldnt work as python is not html. Keep in mind, I am not trying to run this script on the web, but on the kivy launcher. As intended, it should not open the webbrowser but instead show the page in a box built

问题 How to NOT share session between multiple browser tabs ? I am using Spring Security in JSP/Servlet application and I want to know "How can we achieve the behavior with Spring Security where user is forced to login again whenever he changes the browser tab ?" . Disclaimer Question is similar to this Question and this question, but since both the questions are too old (i.e. 4,7 years old) I am sure there must be some way to achieve that today, isn't it ? 回答1: On successful login put some value

问题 I have a problem with an Angular application that I update very often. I would like to avoid the browser cache and I am trying several alternatives but none of them work. The first thing is that I have very difficult to test if the solution works because when I upload a new version, sometimes I see it without having to do more than refresh the page, and other times I need to open the console and force the refresh emptying cache. I tried to include in the request header, Cache-Control: no

问题 I have a little problem with caching the images in the browser for my app-engine application I`m sending last-modified, expires and cache-control headers but image is loaded from the server every time.

问题 How can you scroll to the end of a System.Windows.Forms.WebBrowser programmatically? 回答1: ctlWebBrowser.Document.Body.ScrollIntoView(false); The boolean parameter for ScrollIntoView() is true to align the scrollbar with the top of the document, and false to align the scrollbar with the bottom of the document. MSDN documentation here: HtmlElement.ScrollIntoView 回答2: I'm setting DocumentText property of the WebBrowser control (with html and body tags) and Document.Body.ScrollIntoView(false)

问题 I moved my files to a new server and I had a script that instantly showed output on every echo to the browser, but this isn't working on the new server. Here is my test code: @ini_set('output_buffering', 0); @ini_set('implicit_flush', 1); for ($i = 0; $i < ob_get_level(); $i++) ob_end_flush(); ob_implicit_flush(1); ignore_user_abort(true); set_time_limit(0); $max_wait_time = 30; $begin_time = microtime(true); $elapsed_time = 0; while(!connection_aborted()) { echo $i++.str_repeat(' ', 1020).'
