阅读更多关于 Browser Detection

What's the best / simplest / most accurate way to detect the browser of a user? Ease of extendability and implementation is a plus. The less technologies used, the better. The solution can be server side, client side, or both. The results should eventually end up at the server, though. The solution can be framework agnostic. The solution will only be used for reporting purposes. On the server you're pretty much limited to the UserAgent string the browser provides (which is fraught with problems, have a read about the UserAgent string's history ). On the client (ie in Javascript), you have more

What is better: CSS hacks or browser detection?

阅读更多关于 What is better: CSS hacks or browser detection?

问题 Commonly when I look around the Internet, I find that people are generally using CSS hacks to make their website look the same in all browsers. Personally, I have found this to be quite time consuming to find all of these hacks and test them; each change you make you have to test in 4+ browsers to make sure it didn't break anything else. About a year ago, I looked around the Internet for what other major sites are using (Yahoo, Google, BBC, etc) and found that most of them are doing some form

Easiest/Lightest Replacement For Browser Detection jQuery 1.9?

阅读更多关于 Easiest/Lightest Replacement For Browser Detection jQuery 1.9?

I had several clients complain yesterday that some code stopped working. Apparently it comes down to plug-ins using the now deprecated jQuery.browser which stopped working yesterday when jQuery 1.9 was released. I (quickly) looked at the 1.9 change docs and it seems like they want me to substitute some pretty heavy libraries just for that one function. Is there a recommended lightest weight plug-in or code snippet to restore that functionality? For what these sites need, it's very basic; I only need the most basic detection of IE vs FF vs everyone else. Suggestions? I've use the following code

This question already has an answer here: How to Identify Microsoft Edge browser via CSS? 4 answers I would like to target Edge and have flexbox behave simliar to Firefox 33 / Chrome, for more detail see this question . Can one target Edge in CSS? Raptor To target Edge, we can check for -ms-ime-align support, Edge being the only Microsoft browser that supports this property: @supports (-ms-ime-align: auto) { .selector { color: red; } } Or this one-liner (that one works on Edge and all IEs also): _:-ms-lang(x), .selector { color: red; } Further explanation, including variants to support

How to find out about the User Agent in GWT

阅读更多关于 How to find out about the User Agent in GWT

问题 I am trying to write browser specific code. Is there a GWT API to find out which browser the client is using? 回答1: The GWT Developer's Guide page on Cross-Browser Support gives a JSNI function that returns the UserAgent string. Note, however, that you probably want to use Deferred Binding to write browser-specific code, instead of detecting the UserAgent. Edit: Kasturi points out Window.Navigator.getUserAgent(), which is implemented like so: /** * Gets the navigator.appName. * * @return the

$(window).load(function () { if($.browser.msie && $.browser.version=="6.0") { // do stuff } }); Just realized that $.browser has been depreciated in 1.3. What is the new method for detecting IE, specially IE6. The jQuery documentation for jQuery.browser shows the following warning. (Emphasis is mine.) Because $.browser uses navigator.userAgent to determine the platform, it is vulnerable to spoofing by the user or misrepresentation by the browser itself. It is always best to avoid browser-specific code entirely where possible. Instead of relying on $.browser it's better to use libraries like

For a Chrome Desktop Extension home page, I'm trying to detect whether a user is using Chrome for Desktop or Chrome for Mobile on Android.
