好的，那么什么不起作用？您能否详细解释一下到底出了什么问题？
-
我没有得到日期，它只显示日期 01.01.1970
-
我只发布了我想要日期的代码，因为我已经获取了文本和 ahref 链接，我只想将最后一个日期与今天的日期进行比较，但问题是我只得到这个 01.01.1970 日期
-
请发布更多周围的 HTML。例如，这里没有
<h3>。我看到你为applied调用了getElementsByTagName()，但那是<div>上的一个class，而不是标签。但是，如果没有更多的 HTML 作为上下文，就很难得出结论性的答案。 -
我编辑它的问题是我不能得到第二个日期而不是第一个日期。所以我可以比较今天的日期并将其排列在即将发生的事件中，例如
