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);

selenium.keyPress("css=input.tagit-input.ui-autocomplete-input", "13");

Actions action = new Actions(driver);
action.sendKeys(Keys.RETURN);

如果你只是想按Enter键(python):

from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys

action = ActionChains(driver)
action.send_keys(Keys.ENTER)
action.perform()

我必须在文本中间输入回车键。于是我通过下面的文本发送键函数来实现1\n2\n3:

1\N{U+E007}2\N{U+E007}3

您可以在输入文本的元素对象上调用submit()。

或者，你也可以将Enter键发送给它，如下面的Python代码片段所示:

from selenium.webdriver.common.keys import Keys
element.send_keys(Keys.ENTER) # 'element' is the WebElement object corresponding to the input field on the page
