连接＆＃34; sweetalert＆＃34;方法＆＃34;确认＆＃34;并返回值

Question

我的反馈功能确认存在问题

    sweetAlert: function() {
        window.legacyConfirm = window.confirm;

        window.confirm = function(msg, title, type, callback, params) {
            var title = (title == null) ? 'Warning!' : title;
            var test = 0;
            var type = (type == null) ? 'warning' : type;
            swal({
                    title: title,
                    text: msg,
                    type: type,
                    showCancelButton: true,
                    allowEscapeKey: false,
                    allowOutsideClick: false
                }, function(isConfirm) {
                    if (isConfirm) {return true} else {return false}

            });
        };

    },
    removeItem: function(el) {
        var test;
        var $el      = $(this),
            _comfirm = $el.data('confirm') ? $el.data('confirm') : 'Remove product';
        if (confirm(_comfirm)) {
            console.log("OK")

        }
    }

removeItem方法调用以确认在方法sweetAlert中声明。

确认始终返回undefined，并且不调用循环方法removeItem。

if (confirm(_comfirm)) {
    console.log("OK")
}
