这招对我很管用:

IWebElement element = driver.FindElements(getApplicationObject(currentObjectName, currentObjectType, currentObjectUniqueId))[0];
 ((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].scrollIntoView(true);", element);

瞄准任何元素并发送下键(或上/左/右)似乎也可以工作。我知道这有点像黑客，但我也不太喜欢使用JavaScript解决滚动问题。

例如:

WebElement.sendKeys(Keys.DOWN);

在Java中，我们可以使用JavaScript进行滚动，如下所示:

driver.getEval("var elm = window.document.getElementById('scrollDiv'); if (elm.scrollHeight > elm.clientHeight){elm.scrollTop = elm.scrollHeight;}");

您可以为“elm”分配一个所需的值。scrollTop”变量。

对于一些简单的UI, Selenium可以自动滚动到滚动条中的某些元素，但对于惰性加载UI，仍然需要scrollToElement。

这是我在Java中使用JavascriptExecutor实现的。 你可以在Satix源代码中找到更多细节: http://www.binpress.com/app/satix-seleniumbased-automation-testing-in-xml/1958

public static void perform(WebDriver driver, String Element, String ElementBy, By by) throws Exception {
 try {
  //long start_time = System.currentTimeMillis();           
  StringBuilder js = new StringBuilder();
  String browser = "firefox";

  if (ElementBy.equals("id")) {
   js.append("var b = document.getElementById(\"" +
    Element + "\");");
  } else if (ElementBy.equals("xpath")) {
   if (!"IE".equals(browser)) {
    js.append("var b = document.evaluate(\"" +
     Element +
     "\", document, null, XPathResult.ANY_TYPE, null).iterateNext();");
   } else {
    throw new Exception("Action error: xpath is not supported in scrollToElement Action in IE");
   }
  } else if (ElementBy.equals("cssSelector")) {
   js.append("var b = document.querySelector(\"" +
    Element + "\");");
  } else {
   throw new Exception("Scroll Action error");
  }

  String getScrollHeightScript = js.toString() + "var o = new Array(); o.push(b.scrollHeight); return o;";

  js.append("b.scrollTop = b.scrollTop + b.clientHeight;");
  js.append("var tmp = b.scrollTop + b.clientHeight;");
  js.append("var o = new Array(); o.push(tmp); return o;");

  int tries = 1;
  String scrollTop = "0";
  while (tries > 0) {
   try {
    String scrollHeight = ((JavascriptExecutor) driver).executeScript(getScrollHeightScript).toString();
    if (scrollTop.equals(scrollHeight)) {
     break;
    } else if (driver.findElement(by).isDisplayed()) {
     break;
    }
    Object o = ((JavascriptExecutor) driver).executeScript(js.toString());
    scrollTop = o.toString();
    Thread.sleep(interval);
    tries++;
   } catch (Exception e) {
    throw new Exception("Action error:" +
     " javascript execute error : " + e.getMessage() + ", javascript : " + js.toString());
   }
  }

 } catch (Exception e) {
  try {
   ScreenshotCapturerUtil.saveScreenShot(driver, CLASSNAME);
  } catch (IOException e1) {
   throw new Exception("Save screenshot error!", e1);
  }
  throw e;
 }
}

您可以使用org.openqa.selenium. actions类移动到一个元素。

Java:

WebElement element = driver.findElement(By.id("my-id"));
Actions actions = new Actions(driver);
actions.moveToElement(element);
actions.perform();

Python:

from selenium.webdriver.common.action_chains import ActionChains
ActionChains(driver).move_to_element(driver.sl.find_element_by_id('my-id')).perform()

如果没有效果，在点击之前试试这个:

public void mouseHoverJScript(WebElement HoverElement) {

    String mouseOverScript = "if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseover', true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseover');}";
    ((JavascriptExecutor) driver).executeScript(mouseOverScript, HoverElement);
}
