如何在 Selenium 中执行页面滚动操作?


我们可以在 Selenium 中执行以下与滚动相关的操作 −

垂直滚动

向下滚动到特定像素。

JavascriptExecutor j = (JavascriptExecutor) driver;
// scroll down by 1500 pixel with coordinates 0 and 1500 in x, y axes
j.executeScript("window.scrollBy(0,1500)");

向下滚动到页面底部。

JavascriptExecutor j = (JavascriptExecutor) driver;
// scroll down the bottom of page
js.executeScript("window.scrollTo(0, document.body.scrollHeight)");

示例

垂直向下滚动,直到元素可见。

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.JavascriptExecutor;
public class ScrollDownVisible {
   public static void main(String[] args) {
      System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      String url = "https://tutorialspoint.com/index.htm";
      driver.get(url);
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);
      JavascriptExecutor js = (JavascriptExecutor) driver;
      WebElement terms = driver.findElement(By.linkText("Terms of use”));
      // scroll down the web element for viewing
      js.executeScript("arguments[0].scrollIntoView();",terms);
      driver.close();
   }
}

水平滚动

示例

页面上进行水平滚动。

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.JavascriptExecutor;
public class HScrollDown {
   public static void main(String[] args) {
      System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      String url = "https://tutorialspoint.com/index.htm";
      driver.get(url);
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);
      JavascriptExecutor js = (JavascriptExecutor) driver;
      WebElement meets = driver.findElement(By.linkText("NetMeeting”));
      // scroll down the web element for viewing
      js.executeScript("arguments[0].scrollIntoView();", meets);
      driver.close();
   }
}
