如何检查嵌套循环（Selenium）中未选中的框？
How to check unchecked boxes in nested loop (Selenium)?
关于如何检查 Selenium 中未选中的框，关于公司子类别。创建了一个嵌套循环并尝试了不同的语法......仍然没有得到它。试图将 xpath 设置为 True.. 也没有用。 运行 代码和 lmk 你的想法！

尝试了 continue、break 和 pass 语句，但现在只是不理解 backbutton 代码逻辑，即它去哪里以及如何在检查的子类别的最后一次迭代后仅 运行 它。 .
我看到两个问题。
首先：您尝试在循环之前获取所有复选框，但您应该只获取所有类别，接下来 运行 循环以单击类别，然后搜索当前类别的复选框，对于每个复选框，您应该搜索 checked
其次：此页面显示非标准小部件，因此它不会在 checkbox 中更改 checked，但在某些非标准小部件中设置 class。
还有其他问题。当我单击 category 或 checkbox 时，有时它会显示 popup message 隐藏其他 checkbox 并且代码无法检查它。我单击 label 也检查 checkbox 但它不显示 popup message
在两个类别中有子类别，它仍然需要代码来单击子类别，获取复选框并选中它们。接下来它必须单击按钮返回类别。
有很多 //mat-nav-list - 一个有类别，一个有列和子类别，一个有子类别中的列 - 所以我必须使用索引来处理正确的列表 - 并且 xpath 在 [=22 处开始索引=] - (//mat-nav-list)[1], (//mat-nav-list)[2]。它还需要 ( ) 到 select 正确列表，因为 //mat-nav-list[1] 和 (//mat-nav-list)[1] 表示不同的对象。
