- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?

我引用this在android中实现了Carousel Notifications|关联。一切顺利,能够按预期获取图像。问题是,根据我的要求,我需要根据点击的图像导航到不同的 URL。但是当我尝试实现这一点时,我只能导航到一个 URL(例如:我有 3 张图片和 3 个 URL。如果我点击第二张图片,我需要导航到第二个 URL,但是无论点击哪个图片, 只导航到第三个 URL。)
下面是我的通知和 JSON 的附加代码。

请帮助我根据点击的图像导航到不同的 URL。提前致谢..
最佳答案
终于,我得到了答案。根据我的要求,最多只显示 5 张图像,最少显示一张。因此,我在 for 循环 中使用了一个 switch 案例并获得了所需的输出。我希望我的代码对寻找相同场景的其他人有所帮助。
