问题 If I follow a normal link from http://google.com to http://example.com, normally the http referrer header that my browser sends to example.com is of google.com. Is that header's value always the same as the value of document.referrer inside the example.com page? 回答1: The referer sent by the client in the request header is the same as document.referrer available in JavaScript. However, you can't rely that the referrer information would always be available. It's up to the client to send the

问题 I'm making a small Python program, which calls the webbrowser module to open a URL. Opening the URL works wonderfully. My problem is that once this line of code is reached, the problem is unresponsive. How do I get the program to proceed past this line of code and continue to execute? Below the problematic line is the problematic line, in context: if viewinbrowser == "y": print "I can definitely do that. Loading URL now!" webbrowser.open_new(url) print "Exiting..." sys.exit() The program does

问题 I'm running into a hard limit in Internet Explorer with application protocol's that exceed 508 characters in length. This limit is not enforced in other browsers, chrome etc... The documentation on MSDN(1) does not seem to mention the maximum permissible length in the scheme-specific portion of the URI or total length including scheme. 508 characters is well below general limits for urls in IE reported to be 2083 characters (2). Does anyone know if this is expected behavior, i'm using IE8, or

问题 I am using websockets to transfer video-y images from a server, written in Go, to a client which is an HTML page. My experience shared below is with Chrome. I receive images via the onmessage handler of the websocket. On reception of an image, I might need to complete a number of tasks asynchronously before I can display the image. Even if these tasks are not finished, yet another onmessage() may fire. I do not want to queue images since at this point I'm not able to proceed as rapidly as the

问题 Following code changes property printed (when accessed through javaScript) by browser console and not the actual Use-Agent string sent with the header. Object.defineProperty(navigator, 'userAgent', { get: function () { return 'Mozilla/5.0 (Windows NT 6.2; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0)'; } }); 回答1: This isn't possible from the page itself. The user agent string (as sent in the HTTP request headers) can only be changed via browser extension or browser configuration. 来源： https:/

问题 The problem: What would be the mathematical formula to calculate (regardless of the scrollHeight of the document) how far the bottom of the scrollbar is from it's total bottom (which would be the end of the page). So, for example, when the scrollbar is at the top, I would say the distance in percentages of the bottom of it, from the bottom of the document, would be 0% , and when it's totally scrolled all the way (vertically), it would be 100% . My goal: My goal is to calculate how many pixels
