使用“Element click”以后，无法抓取标签里面的相关信息

在selector的container中使用Element click

container

但无法抓取到标签里面的相关信息

2

以下是网页标签内，需要抓取的信息：

交易历史

实在找不出是哪里出了问题，还请大神赐教！！！

测试网页：https://www.okx.com/metax/nft/ma ... fdae77987ade9270e/2

看下结构

你忽略了一个问题。你是一步到位这么做的。


jiage-tab这一步里面，选择容器比较重要。需要F12 控制台看一下元素。

我这里举例以价格为例。

以div.nft-detail-tab为父集的容器，因为这个已经把click后显示的表格数据包含在内（必须把后面需要提取的内容的元素包起来）




你参考下我的地图。

希望对你有帮助，以后类似需要点击才能显示的数据，如何抓取，有了眉目。

谢谢指点！！！参考您的代码已经弄清楚了你所讲的原理，非常感谢！

你的代码中，我还有一处不太明白，还请赐教！

就是container中的“Multiple”为什么不选中，就抓取不到所需要的数据呢？不是click一次就可以点开我们需要的“交易历史”页面了么？

另外还有一个问题请教一下，所在页面里面有一个“复制按钮”，是否能抓取其所复制的内容？

我自己整理了一份整个页面的信息抓取，结果出现每个页面有2条抓取数据，而且其中1条数据的“container-record”部分数据为null. 不知道是哪里搞错了，还请赐教!!!

看截图是重复了一次。你把container-record 的Multiple取消勾选，Click element uniqueness选择unique text再试试。
