原文: http://blog.gqylpy.com/gqy/307 所谓 UA（User Agent / 用户代理），最初是指浏览器告知网站管理员，本浏览器支持的类型和框架，让网站管理员以支持的模式结构向浏览器发送页面，呈现给用户浏览。演变到今天，网站管理员为了给用户带呈现最佳的页面效果，为了使不同浏览器展现同样的网站页面，通过浏览器获取用户的系统信息，包括硬件平台、系统软件、应用软件和用户个人偏好，然后通过服务器解析后以适合用户的页面类型发送到浏览器。 Python UA库 # 安装 pip install fake-useragent # 使用 from fake_useragent import UserAgent ua = UserAgent() # 随机谷歌UA chrome = ua.Chrome # 随机IE的UA ie = ua.ie # 随机火狐UA firefox = ua.Firefox # 随机浏览器的UA firefox = ua.random # 忽略大小写的，比如：ua.ie可写成ua.IE # 如果实例化时出现报错，可尝试以几种方式实例化： # ua = UserAgent(use_cache_server=False) # ua = UserAgent(cache=False) # ua = UserAgent(verify_ssl=False)

I am trying to make MDN's Javascript Reference available for offline browsing (personal use). I am not the website's owner nor developer, and I can only access its generated output. My first thought was to inject an HTML5 appcache.manifest in the page ; Using manifestR I have generated a list of the page's assets. Then I've tried pointing to my local manifest file using the file:/// protocol, using the http:// protocol and finally using a base64 string , representing the file's contents ( data:text/cache-manifest, ). Nothing seems to work. After googling a bit, I stumbled upon their public FTP

I am trying navigator.MediaDevices.getUserMedia() webrtc to switch the device camera during the call. This functionality is working fine on the desktop browser but on mozilla android it is not working. Here is my code that i am using . var front=false; var myConstraints = { video: { facingMode: (front? "user" : "environment")} }; navigator.mediaDevices.getUserMedia(myConstraints).then(function(stream) { } any idea about this?? jib Phone hardware typically doesn't allow opening both the front and back camera at the same time. Change your code to stop() the existing stream before getting the

Key press event is not working in Mozilla Firefox. I have create a table row dynamically with a text boix in it and that text box has a key press event too. var el = document.createElement('input'); el.type = 'text'; el.name = 'suggest2'; el.setAttribute("id",str2); el.setAttribute("onkeypress","additemifenter(this.id)"); cell2.appendChild(el); row.appendChild(cell2); In google chrome the function additemifenter(this.id) is called. But in firefox that function is not getting executed. What is the alternate way to do this in firefox? Maybe the semicolon at the end would help el.setAttribute(

Mozilla states that "for of loops will loop over NodeList objects correctly". (source: https://developer.mozilla.org/en-US/docs/Web/API/NodeList ) However, this doesn't work in Chrome 43. Is this incorrect documentation or a browser bug? The copied example code used on a page with checkboxes: var list = document.querySelectorAll( 'input[type=checkbox]' ); for (var item of list) { item.checked = true; } Edit: This is shipping in Chrome 51 . Jake Archibald posted a simple fix : NodeList.prototype[Symbol.iterator] = Array.prototype[Symbol.iterator] And for of loops. The docs are correct, but I
