rselenium

问题 I am using Rselenium to obtain an URL, and I don't understand why is not working. My code: links <- remDr$findElements(using = "xpath", value = "//*[@class = 'item-info']") final_link <- data.frame(link = unlist(sapply(links, function(x) {x$getElementAttribute('href')}))) The code of the page: <div class="item-info"> <p class="title product-field" translate="no" data-track-info=" {"description":"title"}" data-force-track=""> <a href="https://www.kobo.com/us/en/ebook/added-youth" class=""

问题 Let's say I want to select all on a page, copy all or save a page, what is the proper command for RSelenium? The example below seems to press the keys in sequence, what I'm trying to do is tell it to hold the "control" key while it presses "s" library(RSelenium) driver <- rsDriver() remDr <- driver[["client"]] remDr$navigate("https://www.google.com/") remDr$sendKeysToActiveElement(list(key = "control", "s")) 回答1: You need to choose element first: webElem <- remDr$findElement("css", "html")

问题 I'm trying to scrape some data from table that uses dropdowns. The table is, "GIC options". The "Term" is "Mid-Term" and the "Interest Type" is "Compound".

问题 I would like to send two simultaneous keys such as ALT+S to the sendKeysToActiveElement( function of the R Selenium webdriver. I only see implementations in Java and C. Can this be done? 回答1: Use below code :- String selectAll = Keys.chord(Keys.ALT, "s"); driver.findElement(By.xpath("YOURLOCATOR")).sendKeys(selectAll); Hope it will help you :) 回答2: If you want to send a single keystroke then use: cl$sendKeysToActiveElement(sendKeys = list(key = "tab")) If you press more than two keystrokes
