当您不想搜索任何定位器时，您可以使用Robot类。例如,

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);

现在Selenium 2已经发布了，发送一个Enter键会更容易一些，因为你可以使用Selenium .webdriver.remote.webelement. webelement类的send_keys方法(这个示例代码在Python中，但在Java中存在相同的方法):

>>> from selenium import webdriver
>>> wd = webdriver.Firefox()
>>> wd.get("http://localhost/example/page")
>>> textbox = wd.find_element_by_css_selector("input")
>>> textbox.send_keys("Hello World\n")

对于每个使用JavaScript / Node.js的人来说，这对我来说是有效的:

driver.findElement(By.xpath('xpath')).sendKeys('ENTER');

Ruby:

driver.find_element(:id, "XYZ").send_keys:return

也可以使用Action界面来实现。在WebDriver的情况下-

WebElement username = driver.findElement(By.name("q"));
username.sendKeys(searchKey);
Actions action = new Actions(driver);
action.sendKeys(Keys.RETURN);
action.perform();

Java

driver.findElement(By.id("Value")).sendKeys(Keys.RETURN);

OR,

driver.findElement(By.id("Value")).sendKeys(Keys.ENTER);

Python

from selenium.webdriver.common.keys import Keys
driver.find_element_by_name("Value").send_keys(Keys.RETURN)

OR,

driver.find_element_by_name("Value").send_keys(Keys.ENTER)

OR,

element = driver.find_element_by_id("Value")
element.send_keys("keysToSend")
element.submit()

Ruby

element = @driver.find_element(:name, "value")
element.send_keys "keysToSend"
element.submit

OR,

element = @driver.find_element(:name, "value")
element.send_keys "keysToSend"
element.send_keys:return

OR,

@driver.action.send_keys(:enter).perform
@driver.action.send_keys(:return).perform

C#

driver.FindElement(By.Id("Value")).SendKeys(Keys.Return);

OR,

driver.FindElement(By.Id("Value")).SendKeys(Keys.Enter);
