I'm sure you've ever seen this in action. A website that states hey you're on MacOS download this specific Mac version. Or download the Windows EXE here.
It mainly comes down to downloads, but there can be some cool advantages of knowing a users browsers and system.
In today's article, we will be using the
navigator API to get the
The end result will look like this:
HTML Document permalink
For our demo we will be created a simple card that we can render some information in.
<div class="card" id="os_card"></div>
CSS Styling permalink
Now let's make the card look more appealing by centering it and using some colors.
font-family: Roboto, "Helvetica Neue", Arial, sans-serif;
box-shadow: 0 10px 20px 0 rgba(0, 77, 115, 0.07);
padding: 30px 40px;
Now we can go ahead and find the users OS!
As mentioned, we make use of the
Let's first declare our starting variables.
const card = document.getElementById("os_card");
let os = "Unknown";
We also define a empty OS variable in case we can't find the right one.
Now we are going to check if the OS string returns something familiar.
if (navigator.appVersion.indexOf("Win") != -1) os = "Windows";
if (navigator.appVersion.indexOf("Mac") != -1) os = "MacOS";
if (navigator.appVersion.indexOf("X11") != -1) os = "UNIX";
if (navigator.appVersion.indexOf("Linux") != -1) os = "Linux";
A full string would look something like this (MacOs)
// 5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.183 Safari/537.36
Now we are going to add our string to our card:
card.innerHTML = "Your OS: " + os;
That's it, see the full result in this Codepen.
