最大化、前进、后退、刷新

public static void main(String[] args) {

    System.setProperty("webdriver.chrome.bin", "C:\\Program Files (x86)\\Google\\Chrome\\Application");
    WebDriver driver = new ChromeDriver();
    driver.get("https://www.baidu.com/");
　　 WebElement search_text =driver.findElement(By.id("kw"));
　　 search_text.sendKeys("博客园");
　　 search_text.submit();

    driver.manage().window().maximize();
    //浏览器窗口最大化

    driver.navigate().back();
    //浏览器前进

    driver.navigate().forward();
    //浏览器后退

    driver.navigate().refresh();
    //浏览器刷新
}

获取窗口句柄、切换窗口

public static void main(String[] args) {

    System.setProperty("webdriver.chrome.bin", "C:\\Program Files (x86)\\Google\\Chrome\\Application");
    WebDriver driver = new ChromeDriver();
    driver.get("https://www.baidu.com/");
    WebElement i = driver.findElement(By.xpath("//*[@id=\"lg\"]/map/area"));
    i.click();

    String window1 = driver.getWindowHandle();
    System.out.println(window1);
    //获取浏览器当前窗口句柄

    Set<String> windows = driver.getWindowHandles();
    //获取浏览器所有窗口,用set集合接收

    String window2 = null;
    Iterator<String> set = windows.iterator();
    while (set.hasNext()) {
        String ss = set.next();
        if (!ss.equals(window1)) {
            window2 = ss;
        }
    }
    //使用迭代器遍历set集合

    System.out.println(window1);
    //打印窗口1的句柄

    System.out.println(window2);
    //打印窗口2的句柄

    driver.switchTo().window(window2);
    //切换到窗口2

    driver.switchTo().window(window1);
    //切换到窗口1
}

关闭当前窗口、关闭浏览器

public static void main(String[] args) {

    System.setProperty("webdriver.chrome.bin", "C:\\Program Files (x86)\\Google\\Chrome\\Application");
    WebDriver driver = new ChromeDriver();
    driver.get("https://www.baidu.com/");
    WebElement i = driver.findElement(By.xpath("//*[@id=\"lg\"]/map/area"));
    i.click();
    
    driver.close();
    //关闭当前窗口
    
    driver.quit();
    //关闭浏览器
}
