Java + Selenium自动化测试中，模拟鼠标滚动页面的实现办法

一、模拟滚动到最底层

1.1 使用 JavaScript 执行

java 复制代码

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class ScrollToBottom {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "path_to_chromedriver");
        WebDriver driver = new ChromeDriver();
        driver.get("your_url_here");

        // 使用 JavaScript 滚动到页面底部
        ((JavascriptExecutor) driver).executeScript("window.scrollTo(0, document.body.scrollHeight);");
    }
}

1.2 循环滚动直到页面底部

java 复制代码

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class ScrollToBottom {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "path_to_chromedriver");
        WebDriver driver = new ChromeDriver();
        driver.get("your_url_here");

        long lastHeight = (long) ((JavascriptExecutor) driver).executeScript("return document.body.scrollHeight");
        while (true) {
            ((JavascriptExecutor) driver).executeScript("window.scrollTo(0, document.body.scrollHeight);");
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            long newHeight = (long) ((JavascriptExecutor) driver).executeScript("return document.body.scrollHeight");
            if (newHeight == lastHeight) {
                break;
            }
            lastHeight = newHeight;
        }
    }
}

1.3 使用 Actions 类模拟滚动（效果可能因浏览器而异）

java 复制代码

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;

public class ScrollToBottom {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "path_to_chromedriver");
        WebDriver driver = new ChromeDriver();
        driver.get("your_url_here");

        Actions actions = new Actions(driver);
        actions.sendKeys(Keys.PAGE_DOWN).perform();
        actions.sendKeys(Keys.PAGE_DOWN).perform();
        // 可以多次重复 PAGE_DOWN 操作，或者结合其他操作模拟滚动到底部
    }
}

二、模拟少量滚动

2.1 使用 Actions 类模拟少量滚动

java 复制代码

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;

public class PartialScroll {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "path_to_chromedriver");
        WebDriver driver = new ChromeDriver();
        driver.get("your_url_here");

        Actions actions = new Actions(driver);
        actions.sendKeys(Keys.PAGE_DOWN).perform();
        // 这是一次模拟按下 Page Down 键进行滚动

        // 可以根据需要再次执行少量滚动操作
        actions.sendKeys(Keys.ARROW_DOWN).perform();
    }
}

2.2 使用 JavaScript 进行部分滚动

java 复制代码

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class PartialScroll {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "path_to_chromedriver");
        WebDriver driver = new ChromeDriver();
        driver.get("your_url_here");

        // 使用 JavaScript 滚动一小段距离
        ((JavascriptExecutor) driver).executeScript("window.scrollBy(0, 200);");
    }
}
