尝试填写弹出窗口数据并应用我的输入

Question

对于在 Windows 环境中使用 Python、Selenium 和 Chromedriver 进行编程，我完全是新手，尽管我熟悉在 UNIX 环境中使用 Perl 和 HTML 执行类似的任务。我的所有软件包都是最新的当前版本。我这样做只是为了好玩，让我在退休后保持思维活跃。

我编写了一个Python程序来从网站上抓取数据

https://www.kijijiautos.ca/cars/gmc/canyon/#ml=%3A&ms=9900%3B13&od=up&p=5000%3A&sb=p&yc=2024% 3A2024。我想使用“设置位置”按钮输入我的邮政编码（加拿大的）。我正在尝试使用 Chromedriver 命令来模拟我手动执行的操作。我会手动单击“设置位置”按钮，这会弹出一个新的小窗口。然后我会输入我的邮政编码并按 Enter 键以启用它。接下来，我单击“半径”字段并选择“1000”选项。然后我会单击“限制半径到省份”复选框来启用它。接下来，我将单击“nnn 结果”字段，然后输入数据，窗口将消失，网页将更新我的搜索结果。

我试图在我的编程中模拟这一点，但我根本看不到我的数据正在更新网页。当我在更新之前和之后转储元素数据时，数据永远不会改变。这是因为它失败并显示“半径”字段的“您不能选择禁用选项”，因为在数据成功输入“邮政编码”字段之前它被禁用。

我不知道我做错了什么。任何意见将不胜感激。请注意，我的程序保存了 Webdriver 执行的日志，因此我可以看到其中的任何错误 - 没有任何错误表明我可以看到。

我期待数据更新网页，正如我上面所解释的。

您无需切换到新窗口。相反，您应该与模式中的元素进行交互。因此删除了切换到新窗口的部分，因为模式位于同一窗口内。我添加了等待，以确保元素在与元素交互之前可点击或可见，以便发生预期的操作。
