modernizr

I'm writing an Angular 2 app but am conscious that some users may not be using a browser that can support Angular 2. I have a check for whether Javascript is enabled, I am more interested in whether the user's browser doesn't support certain JS/HTML5/other features required by Angular 2. What would be the best way to assess whether the user's browser supports Angular 2, and display a message if not? I'm aware of e.g. Modernizer , but not sure where to begin as Modernizer's focus seems to be on assembling compatibility checks piecemeal rather than providing a solution that checks for

Some @font-face fonts don't play nice with non-cleartype settings (gets really choppy on the edges) Is there a way to detect this via javascript so that I can do a modernizr-style class addition to the body if cleartype is off so I can use this in my CSS In IE 6+ you can check the screen.fontSmoothingEnabled property. Otherwise you need to use an html 5 canvas to check for this. Details here . 来源： https://stackoverflow.com/questions/4328558/can-you-detect-if-cleartype-is-enabled-on-pc-via-javascript

Normally I would favour feature detection instead, but I need to find out whether a device is iOS because of the way they handle videos as per this question YouTube API not working with iPad / iPhone / non-Flash device 回答1: Detecting iOS I am not a fan of User Agent sniffing, but here is how you would do it: var iOS = /iPad|iPhone|iPod/

I have an app called Pano2VR which outputs both HTML5 and SWF. I need the HTML5 for iOS device users. However, IE does not render this "HTML5" output at all. It seems their output uses CSS3 3D transforms and WebGL, one or more apparently unsupported in IE9. So, for those users I need to display the Flash version. I was planning to use an IFRAME and either pass the SRC via a

You can use CanvasRenderer instead of WebGLRenderer . About WebGL detection: 1) Read this WebGL wiki article: http://www.khronos.org/webgl/wiki/FAQ if (!window.WebGLRenderingContext) { // the browser doesn't even know what WebGL is window.location = "http://get.webgl.org"; } else { var canvas = document.getElementById("myCanvas"); var context = canvas.getContext("webgl"); if (

However the $.browser is deprecated and will be removed or is already removed (Yeaaaay again!!!!). So, what is modernizr's alternative for $.browser in this case? filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale"); /

I'm looking to build a new website and want to take a responsible "mobile-first" approach. One tenet of this methodology is to only load what you need, and to avoid including large wasteful libraries and frameworks until you actually need them. For this I intend to use modernizr2 to test for features and then load only required files and libraries. On the javascript side, I'm really interested in using something like zepto.js ( http://zeptojs.com/ ) which is a tiny javascript library (2-5k) optimized for mobile webkit (and mobile webkit alone) while maintaining a jquery compatible syntax. It's
