webdriver鼠标上下滑动

有时候我们需要对窗口显示的页面上下滑动，以显示当前正在处理的位置，这就需要用到webdriver模拟鼠标上下滑动

        driver.findElement(By.linkText("知乎- 与世界分享你的知识、经验和见解")).click();System.out.println("进入知乎首页");Thread.sleep(5000);for(String winHandle:driver.getWindowHandles()){driver.switchTo().window(winHandle);}driver.close();Thread.sleep(2000);for(String winHandle:driver.getWindowHandles()){driver.switchTo().window(winHandle);}Thread.sleep(2000);Actions action = new Actions(driver);-------------------------------------------声明一个动作WebElement xia = driver.findElement(By.xpath("//*[@id='help']/a[3]"));----------找到向下滑动到的元素位置action.moveToElement(xia).build().perform();------------------------------------执行滑动动作Thread.sleep(1000);WebElement shang = driver.findElement(By.xpath("//*[@id='container']/div[2]/div/div[2]/div"));----------找到向上滑动到的元素位置
        action.moveToElement(shang).build().perform();----------------------------------执行滑动动作

        System.out.println("鼠标下拉结束");
