我有一个 div 元素并想检索它的子元素。为了做到这一点，我需要将它们全部显示出来，所以我决定需要滚动查看它们。问题是，我得到了我的元素，但是当我打电话时：

((JavascriptExecutor) driver).executeScript("arguments[0].scrollBy(0,250)",element);

其中 element 是一个 WebElement 对象我得到这个堆栈跟踪：

你可以试试下面的代码：

//Get div element having scroll bar you want to do
WebElement scrollArea = driver.findElement(By.xpath("//")); 

// Initialize Javascript executor
JavascriptExecutor js = (JavascriptExecutor) driver;

// Scroll inside web element vertically (e.g. 1000 pixel)
js.executeScript("arguments[0].scrollTop = arguments[1];",scrollArea, 1000);    
Thread.sleep(1000);`

如果页面中已经加载了 div 子项，则无需滚动页面来选择它们。

Incase div 和元素未加载然后滚动尝试下面的代码。

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