嗨，我正在开发饼图和圆环图。因此，就像加载页面时饼图将在圆环图中打开一样。通过单击圆环图，它将打开另一个圆环图。并且有一个链接，单击该链接即可进入初始状态。
这是我的 fiddle - Fiddle link
无论如何，我在这里发布我的代码 -

现在基本上我的问题很小了。我需要我的反向链接位于页面的左上角位置。因此，如果我将链接的 div 标签移动到图表上方，则该链接不起作用，但如果我将其放在它起作用之后。所以，我的问题是为什么它不起作用以及我能做些什么来使它起作用。
如果这是一件非常简单的事情，请原谅我。
最佳答案
是一个z-index问题。 div-> 图表位于 div-> 链接之上，您无法点击它。
将 position:relative;z-index:100 置于div->链接
关于javascript - 后退在 HTML 中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41485298/
