browser

问题 First, I needed a way to force browser always load .css and .js files. I solved it by putting a sufix in the files: Before: <script type="text/javascript" src="file.js"></script> After: <script type="text/javascript" src="file.js?v=1"></script> That aparently worked. Now, I need to know if that really worked. Sure, I can edit the file and check the changes in my browser but I need a way more specific, something like an option in the browser that show "File loaded from the cache" / "New file

问题 When aggressively caching CSS and other files, you can force the user to update to the latest version of the stylesheet by renaming the file and linking to the new copy (eg, style.123.css renamed to style.124.css ). A different method often used instead of renaming the file is to pass a URL parameter, (eg, style.css?ver=123 which is later changed to style.css?ver=124 ). Do all browsers support the latter method for downloading a new copy of the stylesheet? Are there any disadvantages to using

问题 I have an XSLT file for styles in XML. The XSLT is accessible via a URL (http://someurl/somefile.xsl) without problems. When I insert the same URL into an xml-stylesheet processing instruction, it only renders plain text in browsers (FF, IE), <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="http://someurl/somefile.xsl"?> <rootElement>...</rootElement> but when I use a local file path (file downloaded to same folder as the XML file), it works like a charm: <?xml

问题 This question already has answers here : Find what javascript changes the DOM? (2 answers) Closed 6 years ago . I'm trying to look at the html produced by a jQuery tooltip plugin (qTip v1). The tooltip only appears when I hover over the element with my mouse pointer. Normally I'd just inspect the html or dig deeper with Chrome's developer console, but as soon as I do that the tooltip disappears because the mouseover event ends. The tooltip's position is outside the normal flow of the document

问题 I have a long-running report and want to show a wait-spinner to the user while it's generating. I have made this work already but am not sure I'm doing it the best or right way. This is using ColdFusion but it could be any language I guess. At the top of the page, I have some Javascript (jQuery) that shows a wait-spinner plus there's a documentReady handler where I take the spinner down. I flush the output ( if it matters) and then the rest of the code works on the report contents. This wasn

问题 I am currently working with angular animations. Therefore I figured out two possible methods to attach animations to components. In the following I am describing them as State/Transition-Animations and Query-Animations. In this question I mainly want to know if there is a performance difference in going for one or the other way!? 1. State/Transition-Animations .html <div [@animation_foo]/> .ts trigger('animation_foo', [ state('true', style({...}), state('false', style({...}) transition('true

问题 I'm doing a small project in Python and I would like to browse a file or directory to get their path. I'm using Tkinter and I was abble to find only a file browser: filename = tkFileDialog.askopenfilename(parent=root,title='Open file to encrypt') or only a directory browser: dir = tkFileDialog.askdirectory(parent=root, title='Open file to encrypt') Is it possible to combine these two? THank you for all the answers! 回答1: No, it's not possible to combine them. The file browser and directory

问题 These days, I have read some documents about setTimeout, setInterval. I have learned that the Javascript is a single thread which will only execute one piece of code per time. At the same time, if there is a event happens, it will be pushed into the event queue and block until appropriate time. I want to to know, when many events are blocked waiting to execute at the same time. Is these events have different priorities, so the high priority event will execute before the low ones. Or just a

问题 I am using HttpWebRequest for REST services which uses some basic authentication that relies on JSESSIONID cookie. I need to pass that cookie to WebBrowser control to reuse that session, but didn't find any usable solution that would allow me to pass that cookie in the Browser's cookie store. Is there any way? The only way that I can think of now is to use Naviagate(url, null, MANUALLY_CONSTRUCTED_HEADER) which is kind of brute-force. Yes, and really have to use WebBrowser for this kind of

问题 From my little experience in web API, same origin policy is a policy of browsers i.e, browser doesn't allow to make requests to other hosts rather than the origin. I wonder how it is possible to enable CORS from server side(talking about ASP.net Web API)? This is how i enable CORS in webAPI namespace WebService.Controllers { [EnableCors(origins: "*", headers: "*", methods: "*")] public class TestController : ApiController { // Controller methods ... } } If CORS is a browser thing, isn't it
