如何在 Playwright 中使用 Xpath 与 Iframe 交互

编程问答 2022-05-08

问题描述

我正在尝试切换到 iframe，以便我可以填充一个框。 iframe 有一个动态 ID，所以我不能使用它，它有一个类和一个标题，我已将其转换为 XPath。但是，当切换到 iframe 时我似乎没有收到错误，但是当它尝试填充它时会出现错误。这是我的代码。

iframe1 = page.query_selector('xpath=//iframe[@title="payment"]').content_frame()
time.sleep(5)
iframe1.fill('//*[@id="cardCvc-input"]','123')

错误
