硒不向下滚动

Question

我的硒有问题。 我想向下滚动页面，并创建了此方法：

public static void scrollDownToEndOfPage()
    {
        By locator;
        locator = By.xpath("//label[contains(text(),'Blocked advertisers')]//ancestor::nz-form-item//nz-select//input");
        WebDriver driver2 = WebDriverMgr.getDriver();
        JavascriptExecutor js = (JavascriptExecutor) driver2;
        js.executeScript("window.scrollTo(0, document.body.scrollHeight)");
        ((JavascriptExecutor)driver2).executeScript("window.scrollTo(0, document.body.scrollHeight)");
        js.executeScript("window.scrollBy(0,250)");
        js.executeScript("arguments[0].scrollIntoView();", locator);
    }

当我调试没有任何反应时，这是日志

Wed Dec 18 18:35:14 IST 2019:INFO: WebDriver: Script - window.scrollTo(0, document.body.scrollHeight)
Wed Dec 18 18:35:14 IST 2019:INFO: WebDriver: Script - window.scrollTo(0, document.body.scrollHeight)

这是我运行滚动条后的屏幕

页面是从屏幕侧面打开的绘图，我想向下滚动它，有人可以建议吗？

解决方案如Sooraj的建议

 public static void scrollToElement(By locator)
    {

      //  locator = By.xpath("//label[contains(text(),'Blocked advertisers')]//ancestor::nz-form-item//nz-select//input");
        WebDriver driver2 = WebDriverMgr.getDriver();
        WebElement element = driver2.findElement(locator);
        JavascriptExecutor js = (JavascriptExecutor) driver2;
       // js.executeScript("window.scrollTo(0, document.body.scrollHeight)");
      //  ((JavascriptExecutor)driver2).executeScript("window.scrollTo(0, document.body.scrollHeight)");
      //  js.executeScript("window.scrollBy(0,250)");
        js.executeScript("arguments[0].scrollIntoView();", element);
    }

Answer 1

尝试使用javascript scrollIntoView并在不可见区域传递要与之交互的元素：

JavascriptExecutor js = (JavascriptExecutor) driver;
WebElement element = driver.findElement(locator);
js.executeScript("arguments[0].scrollIntoView();", element);
