Identifying the 'request desktop site' mode on iOS Mobile Safari and Chrome: A step-by-step guide

Is there a way to detect when users on iOS mobile Safari or Chrome use the "request desktop site" feature and send them the iPad version of my website? It seems that only the user-agent is different in that mode, making it impossible to detect. Any suggestions?

My website has three versions: desktop, tablet, and smartphone. The tablet version is essentially a static version of the dynamic desktop version, which heavily utilizes JavaScript (including parallax effects).

Answer №1

For the answer to this query, kindly refer to:

It's currently functioning flawlessly..

In essence, iPads in 'Desktop mode' present themselves as MacIntel, despite the fact that no Mac possesses a touchscreen; thus, you need to identify a MacIntel system with touch capability:

let isIOS = /iPad|iPhone|iPod/.test(navigator.platform) ||
(navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1)

However, it is strongly recommended to review the original solution -- full credit goes there:

Answer №2

Instead of using cookies/sessionStorage to detect changes in the user agent, I came across a more efficient method. By comparing navigator.platform with navigator.userAgent, you can easily determine if the user is on an iOS device. This approach eliminates the need for additional scripts like those mentioned in this article and this GitHub gist.

This method is specifically tailored for iOS devices, as Chrome's "request desktop site" feature automatically updates the viewport. Therefore, this check may not be necessary when using Chrome.

var iOSAgent = window.navigator.userAgent.match(/iPhone|iPod|iPad/);
var iOSPlatform = window.navigator.platform && window.navigator.platform.match(/iPhone|iPod|iPad/);
var iOSRequestDesktop = (!iOSAgent && iOSPlatform);

Answer №3

Ingenious solution: leverage platform.maxTouchPoints when working with iOS 13+. Surprisingly, this attribute remains accessible even when switching to the desktop view, unlike on a traditional desktop Safari where it is not present.
