Identifying the Operating System and Applying the Appropriate Stylesheet

I am trying to detect the Windows operating system and assign a specific stylesheet for Windows only. Below is the code snippet I have been using:

$(function() {
        if (navigator.appVersion.indexOf("Win")!=-1)
            {
                $(document.body).append("<link rel='stylesheet' href='../assets/scss/ts-v2-window-style.css'>");
            }
        });

The code works as expected by excluding Mac users and applying the styles to Windows users, however, I am encountering an issue where it does not recognize $. Can anyone spot what might be wrong with this code and provide guidance on how to fix it?

Your help would be greatly appreciated. Thank you.

Answer №1

Ensure you load jQuery before your script to successfully use the $ symbol. The $ symbol is a part of the jQuery library, and it may not be available when your script runs. Include the following code in your HTML:

<script src="path_to_jquery_lib"></script>
<script>
//your script as in question
</script>

The order of these scripts is crucial. Additionally, $(function() {}) is a jQuery construct used to check for the DOM loaded event.
