对于那些使用WebDriverJS key的人。RETURN将被引用为

webdriver.Key.RETURN

一个更完整的例子作为参考可能也会有所帮助:

var pressEnterToSend = function () {
    var deferred = webdriver.promise.defer();
    webdriver.findElement(webdriver.By.id('id-of-input-element')).then(function (element) {
        element.sendKeys(webdriver.Key.RETURN);
        deferred.resolve();
    });

    return deferred.promise;
};

你只需要这样做:

final private WebElement input = driver.findElement(By.id("myId"));
input.clear();
input.sendKeys(value); // The value we want to set to input
input.sendKeys(Keys.RETURN);

尝试使用XPath表达式搜索元素，然后，以下代码工作:

driver.findElement(By.xpath(".//*[@id='txtFilterContentUnit']")).sendKeys(Keys.ENTER);

import org.openqa.selenium.Keys

WebElement.sendKeys(Keys.RETURN);

import语句是针对Java的。对于其他语言来说，情况可能有所不同。例如，在Python中，它是from selenium.webdriver.common.keys import Keys

对于使用XPath的Selenium WebDriver(如果键是可见的):

driver.findElement(By.xpath("xpath of text field")).sendKeys(Keys.ENTER);

or,

driver.findElement(By.xpath("xpath of text field")).sendKeys(Keys.RETURN);

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);
