How to set a cookie when a link is clicked (jQuery)?

Question

css

There is a link, when you click on it, the style of the block changes (a class is added).
Accordingly, it should work on the entire site until the browser is closed.
How to remember this action in a cookie?

$(".special__link--imgoff").click(function(e){
    $("*:not(.sp_ignored) img").addClass('imgoff');
    e.preventDefault();
});

Answer 1

And why pull the cookie and then drag it back and forth. I would do this:

$(".special__link--imgoff").click(function(e){
    $("*:not(.sp_ignored) img").addClass('imgoff');
localStorage.setItem("class", "imgoff");
    e.preventDefault();
});
