有以下几种按键方式- c#:

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

OR

OpenQA.Selenium.Interactions.Actions action = new OpenQA.Selenium.Interactions.Actions(Driver);
action.SendKeys(OpenQA.Selenium.Keys.Escape);

OR

IWebElement body = GlobalDriver.FindElement(By.TagName("body"));
body.SendKeys(Keys.Escape);

Java / JavaScript:

你可能也可以用这种方式，在非母语的情况下:

public void triggerButtonOnEnterKeyInTextField(String textFieldId, String clickableButId)
{
    ((JavascriptExecutor) driver).executeScript(
        "   elementId = arguments[0];
            buttonId = arguments[1];
            document.getElementById(elementId)
                .addEventListener("keyup", function(event) {
                    event.preventDefault();
                    if (event.keyCode == 13) {
                        document.getElementById(buttonId).click();
                    }
                });",

        textFieldId,
        clickableButId);
}

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);

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);

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);

driver.findElement (By.id(“价值”).sendKeys (Keys.RETURN);或driver.findElement (By.id(“价值”).sendKeys (Keys.ENTER);
