Javascript

解决方法很简单:

const element = await driver.findElement(...)
await driver.executeScript("arguments[0].scrollIntoView(true);", element)
await driver.sleep(500);

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);
}

你可能想要访问页面滚动网页元素和网页-硒WebDriver使用Javascript:

public static void main(String[] args) throws Exception {

    // TODO Auto-generated method stub
    FirefoxDriver ff = new FirefoxDriver();
    ff.get("http://toolsqa.com");
    Thread.sleep(5000);
    ff.executeScript("document.getElementById('text-8').scrollIntoView(true);");
}

你可以使用下面的代码片段来滚动:

C#

var element = Driver.FindElement(By.Id("element-id"));
Actions actions = new Actions(Driver);
actions.MoveToElement(element).Perform();

好了

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;
 }
}

我不确定这个问题是否仍然相关，但在参考https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView的scrollIntoView文档后。

最简单的解决办法是

executor.executeScript("arguments[0].scrollIntoView({block: \"center\",inline: \"center\",behavior: \"smooth\"});",element);

这将把元素滚动到页面中央。
