jQuery Change CSS File Dynamically

Use jQuery to dynamically change CSS files, just like a jQuery stylesheet switcher!

The following is how to dynamically change CSS files using pure jQuery:

jQuery code:

The following provide three versions of jQuery code, with slightly different functions:

Version 1: The easiest version, directly change the <link> attribute of the href tag.

$(document).ready(function() {
    $("https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bnav li a").click(function() {
        $("link").attr("href", $(this).attr('rel'));
        return false;
    });
});

Version 2: More complex version, use the jQuery Cookie plugin to save the user's CSS selection and keep the style after the page is refreshed.

$(document).ready(function() {
    if ($.cookie("css")) {
        $("link").attr("href", $.cookie("css"));
    }
    $("https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bnav li a").click(function() {
        $("link").attr("href", $(this).attr('rel'));
        $.cookie("css", $(this).attr('rel'), { expires: 365, path: '/' });
        return false;
    });
});

Version 3: Improved version 2 to reduce flickering during CSS switching.

if ($.cookie("css")) {
    $("link").attr("href", $.cookie("css"));
}

$(document).ready(function() {
    $("https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bnav li a").click(function() {
        $("link").attr("href", $(this).attr('rel'));
        $.cookie("css", $(this).attr('rel'), { expires: 365, path: '/' });
        return false;
    });
});

HTML Code:

HTML code is simple, loading CSS and jQuery files normally in the head. Note the initial value of the <link> attribute of the href tag.

<link rel="stylesheet" type="text/css" href="style1.css">

• Default CSS
• Larger Text
• Something Different

Test link: (Please replace /path/to/ for your actual path)

    language: {
        url: "//cdn.datatables.net/plug-ins/1.10.21/i18n/English.json"
