The script supplied by 'lajuette' is good but it doesn't make you much smarter. The same author explain his thinking behind the script in the above link and basically what he says is:. This is basic for browser type detection but from this littel code its difficult to understand what going wrong Can u add body of isBrowser that will help. Instead of calling functions from whereUWantToDetectBrowserif you write your specific code there, this will cause an error.
And code will not run. Because a browser detects the code which it has to run specific to each browser. So, other will have not effect in IE, as intExp has no effect in other browsers. The best and shortest way to find the browser type for IE is. U can do same for other browser types. Stack Overflow for Teams Ч Collaborate and share knowledge with a private group.

Does anyone have objections to it, because though the other answers are more comprehensive cover version number, etc. But any known problems here. By the way, I tried it on FF and it said Netscape! I tried it on Chrome and it also says netscape :s Ч Toshinou Kyouko Jan 28 '14 at Chrome, Firefox, and Safari return the name "Netscape". Oct 14 '14 at Brave and Edge also return 'netscape' Show 1 more comment. I agree with the theory - and mostly it works in practice too.
But occasionally you need to know the browser. For example how do you detect right-mouse-click in webkit safari or chrome even prototype. Alexey Marzan Alexey Marzan 31 4 4 bronze badges. It is better if you would give a real answer with code here and provide the link as backup where you got that information from. I've corrected my answer. The same author explain his thinking behind the script in the above link and basically what he says is: It is not about browser detection It is about object detection This leads to the knowledge of which browser is used.
What Is This?
If you spot a bug, please feel free to comment below. I try to answer questions too, but it is one person versus the entire worldЕ If you need answers urgently, please check out my list of websites to get help with programming. The user agent is a piece of information that the browser sends to the server. If you are wondering how it looks like, here is an example from Google Chrome:. So yes, it contains general information like the browser, operating system, and other software technologies. We can use this for browser detection, and it is as simple as checking if the browser name is stuck somewhere inside the block of text.
But take note Ч Users can choose to hide the user agent, and it is not a totally reliable method. There are a lot of detection libraries, but this one we are using is called Bowser. As you can see, this one actually relies on the user agent again.
It simply parses the information to make things more convenient, but it has the same old problem Ч Not totally reliable. Credits to David Walsh for this snippet on how to detect the vendor prefix :. For you guys who do not know, each browser has its own unique set of experimental technologies. To use the experimental and non-standard CSS properties, we have to attach a prefix to the property accordingly:.
So yes, we can detect which prefix the browser uses, and determine which engine the browser runs on. Credits to this post on StackOverflow. For example, window. While this is probably one of the most reliable methods, but it takes a lot of time to figure out what is unique to each browser Ч A real pain to keep this list updated. Personally, I will say that none of the above detection methods are reliable. Do feature detection instead. I hope this makes more sense, we just check if the required feature is available; It is very inefficient to try to figure out which browser, which version is capable, which is not.
For example, to check for Chrome browsers Ч if navigator. Browser duck typing Ч Check for unique features that each browser has.
