Update disabled menu item without recreating menu

Hi,

I want to be able to change the enabled state of a menu item for an open menu without recreating the menu.

I tried using a custom function for the disabled attribute which returned a variable's value and then changing the variable and calling $(root).contextMenu(). This only caused the update to take effect if I closed and then opened the context menu again.

I see in the demos there is an example of changing whether a menu item is disabled without recreating the menu here: https://swisnl.github.io/jQuery-contextMenu/demo/disabled-changing.html

Some debugging makes it appear to work because when you click the toggle item it will internally call op.update causing the menu to be updated? I have copied this code to achieve the dynamic update ending up with this:

$(function() {
    disabled = true;
    $.contextMenu({
        selector: '.context-menu-one',
        items: {
            "menu item": {
                name: "Menu item",
                disabled: function() {
                    return disabled;
                }
            }
        }
    });

    window.toggleDisabled = function() {
        disabled = !disabled;
        var $el = $('.context-menu-one');
        var contextMenuRoot = $el.data().contextMenu;
        $.contextMenu.op.update.call($el, contextMenuRoot);
    }
});

This appears to work but I'm a bit hesitant diving in to stuff not in the documentation. Is there another way to achieve what I'm looking to do?

Thanks

Interesting way of doing it. Seems like the right way of doing it. Thing is, if i make this public, i'm not sure it won't act strange, especially with the states of input elements.

But if i would make it a public call, it would probably to exactly the same as that. Probably here: https://github.com/swisnl/jQuery-contextMenu/blob/master/src/jquery.contextMenu.js#L1532

So you are using the correct call, but i'm not sure if i should add it as a public call.

Ok thanks for the response. I'm going to go with it for now, I'll update here if I run into any problems with this approach. So far it's working ok with simple callback menu items and sub menus. I have not used any input elements.
