def scrollToElement(element: WebElement) = {
  val location = element.getLocation
  driver.asInstanceOf[JavascriptExecutor].executeScript(s"window.scrollTo(${location.getX},${location.getY});")
}

Selenium 2尝试滚动到元素，然后单击它。这是因为除非Selenium 2认为元素是可见的，否则它不会与元素交互。

滚动到元素是隐式的，所以您只需要找到项目，然后使用它。

我使用这种方式滚动元素并单击:

List<WebElement> image = state.getDriver().findElements(By.xpath("//*[contains(@src,'image/plus_btn.jpg')]"));

for (WebElement clickimg : image)
{
  ((JavascriptExecutor) state.getDriver()).executeScript("arguments[0].scrollIntoView(false);", clickimg);
  clickimg.click();
}

Selenium的默认行为是滚动，因此元素几乎不在视口顶部的视图中。此外，并非所有浏览器都具有完全相同的行为。这很不令人满意。如果您像我一样记录浏览器测试的视频，那么您需要的是元素滚动到视图中并垂直居中。

下面是我的Java解决方案:

public List<String> getBoundedRectangleOfElement(WebElement we)
{
    JavascriptExecutor je = (JavascriptExecutor) driver;
    List<String> bounds = (ArrayList<String>) je.executeScript(
            "var rect = arguments[0].getBoundingClientRect();" +
                    "return [ '' + parseInt(rect.left), '' + parseInt(rect.top), '' + parseInt(rect.width), '' + parseInt(rect.height) ]", we);
    System.out.println("top: " + bounds.get(1));
    return bounds;
}

然后，为了滚动，你像这样调用它:

public void scrollToElementAndCenterVertically(WebElement we)
{
    List<String> bounds = getBoundedRectangleOfElement(we);
    Long totalInnerPageHeight = getViewPortHeight(driver);
    JavascriptExecutor je = (JavascriptExecutor) driver;
    je.executeScript("window.scrollTo(0, " + (Integer.parseInt(bounds.get(1)) - (totalInnerPageHeight/2)) + ");");
    je.executeScript("arguments[0].style.outline = \"thick solid #0000FF\";", we);
}

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;
 }
}

在滚动的大多数情况下，这段代码都是有效的。

WebElement element = driver.findElement(By.xpath("xpath_Of_Element"));                 
js.executeScript("arguments[0].click();",element);
