如何使用selenium webdriver使用“CTRL A”从文本字段中选择文本？
我正在使用带有ruby的selenium webdriver。
clc = WAIT.until { driver.find_element(:id, 'embed-showembedcode') } driver.action.key_down(:control).click(clc).send_keys("a").key_up(:control).perform 我正在使用但我得到一个错误..
{"testcase":"load: should check embed code","message":"erro r - Cannot perform native interaction: Could not load native events component. \ n [\"[remote server] file:///C:/Users/nachiket/AppData/Local/Temp/webdriver-prof ile20130705-5880-g873k8/extensions/fxdriver@googlecode.com/components/driver_com ponent.js:8738:in `generateErrorForNativeEvents'\", \"[remote server] file:///C: /Users/nachiket/AppData/Local/Temp/webdriver-profile20130705-5880-g873k8/extensi ons/fxdriver@googlecode.com/components/driver_component.js:8771:in `FirefoxDrive
嗯..看看Selenium::WebDriver::Element#text
所以使用：
elem = wait.until { element = driver.find_element(:id, 'embed-showembedcode') element if element.displayed? } puts elem.text # => target text will be printed here
现在要修复错误，我建议你总是做一些机器表示测试，如下所示。 Selenium::WebDriver::Keys提到的映射不需要在你的机器上工作：
require "selenium-webdriver" puts Selenium::WebDriver::Keys::KEYS # => {:null=>"\uE000", :cancel=>"\uE001", :help=>"\uE002", :backspace=>"\uE003", :tab=>"\uE004", # :clear=>"\uE005", :return=>"\uE006",:enter=>"\uE007", :shift=>"\uE008", # :left_shift=>"\uE008", :control=>"\uE009",.. } elem = wait.until { element = driver.find_element(:id, 'embed-showembedcode') element if element.displayed? } driver.action.key_down("\uE009").click(elem).send_keys("a").key_up("\uE009").perform
