RSelenium中的下拉框 [英] dropdown boxes in RSelenium

问题描述

如何与RSelenium中的下拉框进行交互?特别是，我可以使用findElement选择下拉框，但是如何选择它呢?

How can one interact with dropdown boxes in RSelenium? In particular, I can select the dropdown box using findElement but how does one select an option with it?

推荐答案

此处是基于xpath选择下拉列表的代码.

here is the code to select a drop down list based on xpath.

由于下拉列表位于iframe内部，因此我必须先切换到该iframe. 在您的情况下，这可能会容易得多.

Since the dropdown is inside an iframe, I have to switch into that iframe first. It probably is much easier in your situation.
