在RSelenium中打開一個新標簽

Question

如何在RSelenium打開一個新選項卡？ 具體來說，如何指定控制鍵以將“ CTRL + T”發送到窗口？ 我嘗試：

require(RSelenium)
RSelenium::startServer()
dr = remoteDriver()
dr$open()
b = remDr$findElement(using = 'tag', value = "body")
b$sendKeysToElement(list("CONTROL + T")) #this does not work

RSelenium有鍵盤鍵的列表，請參見?selKeys

您可以在鏈接上打開一個新標簽，如下所示：

library(RSelenium)
RSelenium::startServer()
dr <- remoteDriver()
dr$open()
dr$navigate("http://www.stackoverflow.com")
# find the Users tab
webElem <- dr$findElement("id", "nav-users")
dr$mouseMoveToLocation(webElement = webElem) # move to the required element
dr$click(2) # right mouse button click 
webElem$sendKeysToElement(list(key = "control", "t")) # open a new tab by sending ctrl+t

Selenium不支持標簽，但是請參見例如https://code.google.com/p/selenium/issues/detail?id=5572，因此最好在新窗口中打開

webElem$sendKeysToElement(list(key = "control", "w"))
> dr$getWindowHandles()
