如果该对象传递无效:

等待浏览器。executeScript("arguments[0]. scrollintoview()"，等待浏览器。(等到。elementLocated(通过。xpath(“/ / div [@jscontroller = ' MC8mtf '] ")), 1000));

有一个演示滚动到麦克风按钮，在谷歌页面。通过javascript xpath找到它，使用chromedriver和selenium-webdriver。

Start1()在狭窄的窗口中启动浏览器，麦克风按钮不显示。

Start2()在狭窄的窗口中启动浏览器，然后滚动到麦克风按钮。

require('chromedriver');
const { Builder, 
        By, 
        Key, 
        until
      }                = require('selenium-webdriver');

async function start1()  {

  var browser = new Builder()
                    .forBrowser( 'chrome' )
                    .build();
  await browser
        .manage()
        .window()
        .setRect( { width: 80, 
                    height: 1040, 
                    x:-10, 
                    y:0} 
                );
  await browser.navigate().to( "https://www.google.com/" );
}

async function start2()  {

  var browser = new Builder()
                    .forBrowser( 'chrome' )
                    .build();
  await browser
        .manage()
        .window()
        .setRect( { width: 80, 
                    height: 1040, 
                    x:-10, 
                    y:0} 
                );
  await browser.navigate().to( "https://www.google.com/" );
  await browser.executeScript( "document.evaluate(\"//div[@jscontroller='MC8mtf']\", document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue.scrollIntoView(true);");
}

start1();
start2();

这是JavaScript的重复解决方案，但增加了一个等待元素。

否则，如果正在对元素进行某些操作，可能会出现ElementNotVisibleException。

this.executeJavaScriptFunction("arguments[0].scrollIntoView(true);", elementToBeViewable);
WebDriverWait wait = new WebDriverWait(getDriver(), 5);
wait.until(ExpectedConditions.visibilityOf(elementToBeViewable));

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;
 }
}

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

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);

如果您想使用Selenium web驱动程序在Firefox窗口上滚动，其中一种方法是在Java代码中使用JavaScript。JavaScript代码向下滚动(网页底部)如下:

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("window.scrollTo(0, Math.max(document.documentElement.scrollHeight, document.body.scrollHeight, document.documentElement.clientHeight));");
