Question

我正在寻找您的编码方面的帮助，以将数据从Web提取到Excel。

通过网络获取数据：

https://eport.saigonnewport.com.vn/Pages/Common/Containers_new

获取数据的步骤：

将“CátLái”放入“ Khuvựcgiaonhận集装箱”（选择海港）

将容器号放入“容器”字段

取消选择“Chỉvòngluânchuyểncuối”以显示数据表中的所有行

点击搜索以显示数据表-搜索容器信息的结果

问题：从网上抓取到Excel中每一行的数据（分别与找到的每个容器号）似乎与之前的容器号相同结果该容器号的WHILE信息可以为空。对于示例：重复事件时间2“ 10/4/2020 3:07:00 PM” 容器“ TEMU3311320”，而该容器没有事件时间 2。

希望您能给我任何建议以解决此重复问题。随附Excel文件供您参考。谢谢。

Answer 1

在最后一个Next之前，请确保将所有相关的字符串变量分配给vbNullstring，即Array(strEventtime1, strEventtype1, strLocation1, strEventtime2, strEventtype2)中的变量，因为它位于If中，然后是If未满足的先前值将保留在以后的循环迭代中。
