As far as I know you don't even have to wait for document ready to execute this code as the user-agent is not related to the DOM. I landed on this page in , and I see that till IE5 all userAgent string have Trident , I'm not sure if they have changed anything. So checking only for Trident in the userAgent worked for me. I've placed this code in the document ready function and it only triggers in internet explorer.
Tested in Internet Explorer I happened to find this by accident when I was testing if my site worked on IE, and I went to the debugger and clicked the folder icon. It has my scripts, and also a Dynamic Scripts folder that I didn't have. I opened it and found lots of browsertools. Inside them I found stuff like:. So I used these to test if the user's browser was IE. Just note this only works if you want to know if they have IE, not exactly what version of IE they have.

If I could tell which browser they are using that would be great but is not required.

Actually, this "bad practice" is forced by the standards themselves, so it's not the developer's fault Browsers work differently and and the specs are too soft on implementation issues.
In order to make something that is not buggy and not boring as hell one has to do browser detection. I would suggest an other best practice: With modern web development, it's bad practice to support non-Chromium-based browsers with Safari not considered to be Chromium-based at all. Sorry, but this insanity must end at some point and somehow It is better practice today to do "feature detection" over "browser detection".
Ask whether the browser does what you need instead. ChrisRogers - That sounds great and all, but if you need to add some inline styles because of a bug in how IE measures the size of child elements of a flexbox element , then yeah Chris - apologies I'm going to blame IE for stealing my joy and leaving me with bitterness and frustration.

I have not verified your answer yet, but I want to comment one thing: As the first 'if' contains a 'return', you don't need an 'else' afterwards. Just curious, why the heck do they change the user agent line in new versions of IE? MS seriously don't want us to detect their awful web browser.
SameerAlibhai Which sounds good in theory but in practice, especially currently, it's not practical. Sometimes issues arise that a single "feature" detection doesn't encompass and plus certain features have implementation quirks that can only be worked around with knowledge of the browser.
What if I want to do something simple like collect browser statistics? It should be noted that Edge isn't really 'IE12' but is in fact a completely separate browser. Windows 10 comes with both IE11 and Edge installed. Show 22 more comments. IE mode made the back-and-forth between Edge and IE renderings, if not automatic at least configurable.
That was an advantage over Chrome when Google's browser was adopted by IT administrators. Google had, of course, countered with what it dubbed "Legacy Browser Support," or LBS, which was originally a browser add-on, then in , integrated with Chrome itself.
It was an inelegant solution that, unlike Edge, resulted in two open browsers. The disappearance of IE11 — enterprises won't want to use the application once security updates dry up next summer — means that Chrome won't be able to handle the IE-dependent URLs and apps. Almost certainly, Microsoft gave Google a heads up that it was getting ready to ditch IE11 and leave Edge's IE mode as the sole legacy solution.
Users would not have done more with IE than they had to; remember, it was old as Moses and crippled when compared to a modern browser. But Edge? That's going to be different. Once open, Edge may tempt Chrome users into staying with it, running it for more than rendering IE-reliant sites and apps.
Edge may appeal to Chrome users — the former is the latter, more or less — enough, anyway, for some to wonder why they're running two browsers when one will do. We're not saying that this was the only, or even most important reason Microsoft decided to finally kill IE Microsoft's Lyndersay ticked off several in his post, but they were largely boilerplate arguments about Edge's superiority. Internet Explorer long outlived its usefulness and its sell-by date, technology-wise, wasn't long after its October release.
If not for Microsoft's indulgence of its commercial customers and the company's history of backward compatibility and support, IE should have vanished around the time Edge came on the scene. Such a drastic move couldn't have injured Microsoft's browser share any more than the company's actual actions, notably its decision to force users to upgrade IE, which kicked off Chrome's surge starting in early Few browsers can say as much.
