Internet Explorer 11 (IE11) has been a long-standing browser, part of the Microsoft Internet Explorer series that has served countless users over the years. However, with the rapid development of web technologies, it's crucial for developers to detect IE11 to ensure optimal user experience across different browsers.
Detecting IE11 can be useful for various reasons, like providing specific styles or functionality tailored to this specific browser version. In this guide, we will explore different methods to detect Internet Explorer 11 in your web applications.
One common approach to detecting IE11 is using feature detection. This method involves checking if a specific feature or property supported by IE11 is available. For instance, you can check for the presence of the `msCrypto` property, which is unique to IE11's implementation of the Web Crypto API. If the property is present, it indicates that the browser is IE11.
if (window.msCrypto) {
// Code specific to Internet Explorer 11
}
Another way to detect IE11 is by utilizing the user-agent string. While user-agent sniffing is generally discouraged due to its unreliability, in some cases, it might be necessary. The user-agent string for IE11 usually contains "rv:11.0", which can be used to identify the browser.
if (navigator.userAgent.indexOf('rv:11.0') !== -1) {
// Code specific to Internet Explorer 11
}
For a more robust and future-proof approach, you can leverage the conditional comments feature that was available in older versions of Internet Explorer. Although conditional comments are no longer supported in IE11 and later versions, you can still target IE11 exclusively by combining feature detection with conditional comments.

By combining these methods, you can effectively detect Internet Explorer 11 and provide the necessary fallbacks or enhancements for users accessing your web application through this browser.
It's worth noting that as technology evolves, the relevance of detecting specific browsers like IE11 may diminish. Embracing modern web standards and practices, along with a progressive enhancement approach, can help ensure your web application works seamlessly across different browsers without the need for browser-specific detection.
In conclusion, detecting Internet Explorer 11 in your web applications can be achieved through various methods such as feature detection, user-agent string checks, and conditional comments. Choose the approach that best fits your specific requirements while keeping in mind the importance of adopting web standards for a more robust and inclusive user experience.
