I want to offer the right version of a download. The versions I have are: 32-bit Windows 64-bit Windows Linux Detecting Linux using the User Agent field is easy; but is it possible to reliably figure out if Windows is 32-bit or 64-bit? Users might be using weird browsers - IE and Firefox are common, and we probably have an Opera user somewhere; maybe a Chrome user too. I know that 6
我想提供正确的下载版本。 我拥有的版本是: 32位Windows 64位Windows Linux的 使用User Agent字段检测Linux很容易; 但是如果Windows是32位还是64位,是否可以可靠地确定? 用户可能会使用奇怪的浏览器 - IE和Firefox很常见,我们可能在某个地方有Opera用户; 也许是Chrome用户。 我知道64位Windows 7带有32位和64位版本的IE,并且我想向他们发送我的下载的64位版本。 (编辑补充:我知道我应该提供所有选项,但

Working on an idea for a simple HTMLElement wrapper I stumbled upon the following for Internet Explorer and Chrome: For a given HTMLElement with ID in the DOM tree, it is possible to retrieve the div using its ID as the variable name. So for a div like <div id="example">some text</div> in Internet Explorer 8 and Chrome you can do: alert(example.innerHTML); //=> 'some text' o
处理一个简单的HTMLElement包装的想法我偶然发现了以下的Internet Explorer和Chrome: 对于在DOM树中具有ID的给定HTMLElement,可以使用其ID作为变量名来检索div。 所以对于一个div来说 <div id="example">some text</div> 在Internet Explorer 8和Chrome中,您可以执行以下操作: alert(example.innerHTML); //=> 'some text' 要么 alert(window['example'].innerHTML); //=> 'some text' 那么,这
I need to programmatically get the User-Agent of my browser: IE10 on windows 7. That should be an easy job. I tried navigator.userAgent in javascript and HtmlPage.BrowserInformation.UserAgent in Silverlight and both of them return: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .N

I want to provide my visitors the ability to see images in high quality, is there any way I can detect the window size? Or better yet, the viewport size of the browser with JavaScript? See green area here: Cross-browser @media (width) and @media (height) values var w = Math.max(document.documentElement.clientWidth, window.innerWidth || 0); var h = Math.max(document.documentElement.clientHei
我想为我的访问者提供以高质量查看图像的能力,有什么方法可以检测窗口大小? 或者更好的是,JavaScript的浏览器的视口大小? 在这里看到绿色区域: 跨浏览器@media (width)和@media (height)值 var w = Math.max(document.documentElement.clientWidth, window.innerWidth || 0); var h = Math.max(document.documentElement.clientHeight, window.innerHeight || 0); window.innerWidth和.innerHeight 获取包含滚动条
How can I print a message to the error console, preferably including a variable? For example, something like: print('x=%d', x); 安装Firebug,然后您可以使用console.log(...)和console.debug(...)等(请参阅文档以获取更多信息)。 console.error(message); //gives you the red errormessage console.log(message); //gives the default message console.warn(message); //gives the warn message with the exclamat
如何将错误消息打印到错误控制台,最好包含一个变量? 例如,像这样的东西: print('x=%d', x); 安装Firebug,然后您可以使用console.log(...)和console.debug(...)等(请参阅文档以获取更多信息)。 console.error(message); //gives you the red errormessage console.log(message); //gives the default message console.warn(message); //gives the warn message with the exclamation mark in front of it console.info(m
If I understand correctly, according to Douglas Crockford http://javascript.crockford.com/private.html, the "privileged" methods are similar to what we know as "public" methods. and "public" methods are something that's a bit different. Here's how I understand it: "Privileged" methods can access private variables since it is defined inside the
如果我理解正确,根据道格拉斯克罗克福德http://javascript.crockford.com/private.html,“特权”方法类似于我们所知的“公共”方法。 和“公共”方法有些不同。 以下是我的理解: “特权”方法可以访问私有变量,因为它是在定义其余私有变量时在闭包内定义的。 var C = function(){ var private; this.privilegedMethod = function(){ /* blah blah */ }; } var cObj = new C(); “公共”方法是通过原型添加到对象本
I am working with AngularJS for my latest project. In the documentation and tutorials all model data is put into the controller scope. I understand that is has to be there to be available for the controller and thus within the corresponding views. However I dont think the model should actually be implemented there. It might be complex and have private attributes for example. Furthermore one
我正在与AngularJS合作进行我的最新项目。 在文档和教程中,所有模型数据都放入控制器范围。 我明白,必须在那里为控制器提供,并因此在相应的观点内。 但是我不认为模型应该在那里实际实施。 例如,它可能很复杂并且具有私有属性。 此外,人们可能希望在另一个上下文/应用程序中重用它。 把所有东西都放进控制器完全打破了MVC模式。 对于任何模型的行为也是如此。 如果我将使用DCI体系结构并从数据模型中分离行为,则
please help me understand this. You have a function that calls a few methods: function() { methodA(function(){...}); methodB(); methodC(); } From languages that don't have callbacks or anonymous functions I got used to the fact, that the execution doesn't go on until a method returns. So that if I called methodA with the callback, the execution would have to wait until the
请帮我理解这一点。 你有一个调用几个方法的函数: function() { methodA(function(){...}); methodB(); methodC(); } 从没有回调函数或匿名函数的语言中,我习惯了这样一个事实,那就是直到方法返回时,执行才会继续。 所以如果我用callback调用methodA,执行将不得不等待直到方法返回,这将不会是异步的,对吧? 例如,我可以将回调存储到某个对象,并让方法返回。 然后执行methodB和methodC。 当用户点击
