Question

我试图在Selenium Java的新Tab中打开一个链接，但是第一次只有一个链接打开，但是当打开第二个链接时For Loop出错了，任何人都可以帮我解决这个问题。 / p>

这是我的代码。

public class Link_Open_In_New_Tab {

    public WebDriver driver;

    @BeforeTest
    public void OpenBrowser() {

        System.setProperty("webdriver.chrome.driver", "./driver/chromedriver.exe");
        driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.get("https://www.nopcommerce.com/");
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }

    @Test
    public void OpenLink() throws InterruptedException {

        List<WebElement> ProMenu;
        WebElement SubLinks;
        driver.findElement(By.xpath("//ul[@class='top-menu']/li[1]/a")).click();
        ProMenu = driver.findElements(By.xpath("//ul[@class='top-menu']/li[1]/ul[@class='sublist']/li/a"));

        for (int i = 0; i < ProMenu.size(); i++) {

            SubLinks = driver
                    .findElement(By.xpath("//ul[@class='top-menu']/li[" + (i + 1) + "]/ul[@class='sublist']/li/a"));
            Actions act = new Actions(driver);
            act.keyDown(Keys.CONTROL).click(SubLinks).keyUp(Keys.CONTROL).build().perform();
            Thread.sleep(2000);

            String winHandleBefore = driver.getWindowHandle();

            for (String winHandle : driver.getWindowHandles()) {
                driver.switchTo().window(winHandle);
            }

            Thread.sleep(2000);

            driver.close();
            Thread.sleep(2000);

            driver.switchTo().window(winHandleBefore);
            Thread.sleep(2000);

            //driver.findElement(By.xpath("//ul[@class='top-menu']/li[1]/a")).click();
            //Thread.sleep(2000);
        }
    }

}

Answer 1

您必须将鼠标悬停在产品上，才能获取所有sub menus items。之后，您可以使用 Selenium 和 JAVA 中提供的 Actions 类来模拟键盘笔触。

您可以尝试以下代码：

public class Ashish { static WebDriver driver ; public static void main(String[] args) throws InterruptedException { System.setProperty("webdriver.chrome.driver", "C:\\Users\\user***\\Downloads\\chromedriver_win32\\chromedriver.exe"); driver = new ChromeDriver(); driver.manage().window().maximize(); driver.get("https://www.nopcommerce.com/"); Actions action = new Actions(driver); action.moveToElement(driver.findElement(By.xpath("//ul[@class='top-menu']/li[1]/a"))).build().perform(); List<WebElement> element = driver.findElements(By.xpath("//ul[@class='top-menu']/li[1]/ul[@class='sublist']/li/a")); for(WebElement ele:element) { action.keyDown(Keys.LEFT_CONTROL).moveToElement(ele).click().keyUp(Keys.LEFT_CONTROL).build().perform(); } } }

更新1 ：

public class Ashish { static WebDriver driver ; public static void main(String[] args) throws InterruptedException { System.setProperty("webdriver.chrome.driver", "C:\\Users\\user***\\Downloads\\chromedriver_win32\\chromedriver.exe"); driver = new ChromeDriver(); driver.manage().window().maximize(); driver.get("https://www.nopcommerce.com/"); WebDriverWait wait = new WebDriverWait(driver, 10); Actions action = new Actions(driver); action.moveToElement(driver.findElement(By.xpath("//ul[@class='top-menu']/li[1]/a"))).build().perform(); List<WebElement> element = driver.findElements(By.xpath("//ul[@class='top-menu']/li[1]/ul[@class='sublist']/li/a")); System.out.println(element.size()); for(int i = 0 ; i<element.size() ; i++) { action.keyDown(Keys.LEFT_CONTROL).moveToElement(wait.until(ExpectedConditions.elementToBeClickable(element.get(i)))).click().keyUp(Keys.LEFT_CONTROL).build().perform(); ArrayList<String> tabs = new ArrayList<String>(driver.getWindowHandles()); driver.switchTo().window(tabs.get(1)); System.out.println(driver.getTitle()); driver.close(); driver.switchTo().window(tabs.get(0)); } } }

控制台输出：

Answer 2

您试图打开产品菜单中的所有子链接。但是您的子链接xpath指向所有菜单（li[" + (i + 1) + "]/ul[@class='sublist']/li/a）的第一个子链接。因此，您需要按如下所示修改子链接xpath，然后尝试

SubLinks = driver.findElement(By.xpath("//ul[@class='top-menu']/li[1]/ul[@class='sublist']/li[" + (i + 1) + "]/a"));

Answer 3

如果您打算测试链接标题是否按预期工作，那么为什么需要Crtl + click。

根据开发情况，此处的链接是单击而不是ctrl + click，我个人不愿意执行此操作。

创建变量，说int i = 1;

在循环中使用，请进行常规单击并验证标题。然后增加i并返回浏览器。
