在引导浏览中禁用上一个按钮

Question

有这样的旅行

var TourToolTipPoolConfiguration = new Tour({
            name: 'TourToolTipPoolConfiguration',
            steps: [
                {
                    onNext: function (TourToolTipPoolConfiguration) {
                        TourToolTipPoolConfiguration.goTo(3);
                    },
                    element: "#TimeExpireTicket",
                    title: "foo",
                    content: "test1"
                },
                {
                    element: "#DayNumber",
                    title: "foo",
                    content: "test2"
                },
                {
                    element: "#SavePoolConfig",
                    title: "foo",
                    content: "test3"
                }
            ]
        });

step1或step2是可选的，我隐藏了div display：none，但是如果在步骤2中浏览了init，我需要禁用prev按钮，因为step1是隐藏的，该怎么做？我尝试onPrev评估div是否可见但不起作用

Answer 1

您可以简单地使用CSS隐藏它：

button[data-role='prev'] {
  display: none;
}
