Scrolling page in RSelenium

问题

How can I manually scroll to the bottom (or top) of a page with the RSelenium WebDriver? I have an element that only becomes available when it is visible on the page.

回答1:

Assuming you got

library(RSelenium)
startServer()
remDr <- remoteDriver()
remDr$open()
remDr$setWindowSize(width = 800, height = 300)
remDr$navigate("https://www.r-project.org/about.html")

You could scroll to the buttom like this:

webElem <- remDr$findElement("css", "body")
webElem$sendKeysToElement(list(key = "end"))

And you could scroll to the top like this:

webElem$sendKeysToElement(list(key = "home"))

---

And in case you want to scroll down just a bit, use

webElem$sendKeysToElement(list(key = "down_arrow"))

The names of the keys are in selKeys.
