Jquery-UI 可排序 : How to tell if sorting was canceled in stop callback?

Question

我设置了一个带有 stop 回调的可排序对象，并绑定(bind)了 esc 来取消当前排序。在 stop 回调中，如何判断当前排序是取消还是完成？

这是我当前的代码片段:

this.$("tbody").sortable({
    start: function() {
        shortcut.add("esc", function() {
            that.$("tbody").sortable("cancel");
        });
    },
    handle: ".sortable-handle",
    stop: function(e, ui) {
        shortcut.remove("esc");
        // how to check if cancel was called during sorting?
        if (!e.canceled) {
            // save new state 
        }
    }
});

在停止函数中尝试这个。

stop: function(e, ui) {
    if(ui.item.sortable._isCanceled) {
        console.log('Sort action was canceled');
    } else {
        console.log('Sort action was not canceled');
    }
}
