按键javascript ctrl键

Question

Can someone please tell me what's going on with Ctrl key? I've tried like every answer of questions about this matter - none work!

$("body").on("keypress", function(e) {
    if (e.which == 49)
        summon = "SpearMan";
    if (e.which == 50)
        summon = "SwordMan";
    if (e.which == e.ctrlKey) {
        console.log("ctrl");
    }
});

Even in w3schools the example they have doesn't work. Please help.

So I decided to use this plugin and it didn't work for me because it only helps if I have an https://jqueryui.com/selectable/#display-grid . So what I did was to find how it used the ctrl key:

$("body").on("keypress", function(e){
        if(!event.metaKey && !event.ctrlKey) {
            console.log("ctrl");
            gather = true;
        }
});
