为什么我无法使用 Selenium 2 向下滚动页面？

Question

我已经安装了壁虎驱动程序。
我在页面向下滚动时有点困惑。控制台没有向我显示任何错误，因为我写了测试用例失败如果（如果条件失败）：

package PackageQandle;

//import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebElement;
//import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
//import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

//import junit.framework.Assert;

public class Adduser {
    public static void main(String[] args) throws Throwable  {
        System.setProperty("webdriver.gecko.driver","C:/Users/sudhir/geckodriver-v0.18.0-win32/geckodriver.exe");
        FirefoxDriver driver = new FirefoxDriver();
        driver.get("https://prod4.qandle.com");
        WebDriverWait webwait = new WebDriverWait(driver,120);
        webwait.until(ExpectedConditions.elementToBeClickable(driver.findElementByXPath(".//*[@id='login-email']")));
        WebElement web = driver.findElementByXPath(".//*[@id='login-email']");
        web.sendKeys("Anil@gmail.com");
        WebDriverWait webwait1 = new WebDriverWait(driver,20);
        webwait1.until(ExpectedConditions.elementToBeClickable(driver.findElementByXPath(".//*[@id='login-password']")));
        WebElement web1 = driver.findElementByXPath(".//*[@id='login-password']");
        web1.sendKeys("Abc12345");
        WebElement web2 = driver.findElementByXPath(".//*[@id='signInSubmit']");
        web2.submit();

        //Assert.assertEquals(my_Title, my_ExpectedTitle);
        Thread.sleep(5000);

        //JavascriptExecutor j = new JavascriptExecutor();
        String my_Title = driver.getCurrentUrl();
        //System.out.println(my_Title);
        String my_ExpectedTitle = "https://prod4.qandle.com/#/";

        if(my_Title.equals(my_ExpectedTitle)){
             driver.executeScript("Scroll(0,600);");
        }else{
            System.out.println("Test Case Failed");

        }

    }

}

    

我正在使用此代码检查向下滚动页面时出现的元素。

Answer 1

您需要将驱动程序转换为 JavascriptExecutor 类型

JavascriptExecutor jse = (JavascriptExecutor) deiver;
WebElement scrollElement = driver.findElement();
jse.executeScript("return arguments[0].scrollIntoView();", scrollElement);

Answer 2

findElementByXpath 的语法必须是

driver.findElement(By.xpath(".//*[@id='login-password']"));

尝试下面提到的滚动到元素的代码，它对我有用

   driver.get("https://prod4.qandle.com");
  WebDriverWait webwait = new WebDriverWait(driver,120);

  webwait.until(ExpectedConditions.elementToBeClickable(driver.findElement(By.xpath(".//*[@id='login-email']"))));
  WebElement web = driver.findElement(By.xpath(".//*[@id='login-email']"));
  web.sendKeys("Anil@gmail.com");
  WebDriverWait webwait1 = new WebDriverWait(driver,20);
  webwait1.until(ExpectedConditions.elementToBeClickable(driver.findElement(By.xpath(".//*[@id='login-password']"))));
  WebElement web1 = driver.findElement(By.xpath(".//*[@id='login-password']"));
  web1.sendKeys("Abc12345");
  WebElement web2 = driver.findElement(By.xpath(".//*[@id='signInSubmit']"));
  web2.submit();

  //Assert.assertEquals(my_Title, my_ExpectedTitle);
  try {
Thread.sleep(5000);
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
  String my_Title = driver.getCurrentUrl();
  String my_ExpectedTitle = "https://prod4.qandle.com/#/";

  if(my_Title.equals(my_ExpectedTitle)){
      JavascriptExecutor js = (JavascriptExecutor) driver;  
   // Mention the xpath of the element to be scrolled for
       WebElement tempElement=driver.findElement(By.xpath("//*[contains(text(),'Reports')]"));


      ((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", tempElement);
  }else{
      System.out.println("Test Case Failed");

  }

如果您使用的是“Chrome”，请使用：

js.ExecuteScript("arguments[0].scrollIntoViewIfNeeded(true);", e)

对于“Firefox”和“IE”使用：

js.ExecuteScript("arguments[0].scrollIntoView(true);" +
                                     "window.scrollBy(0,-100);", e);
