Question

以下index.jsp有3个超级链接（gmail，google，Facebook，java教程），即使单击超链接后我也会得到相同的窗口句柄值（每次点击都会增加句柄数）。有人可以帮助我解决我的代码错误。

的index.jsp

App.java

import java.io.IOException;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class App {
    public static void waitForNumberOfWindowsToEqual(final WebDriver driver, final int numberOfWindows) {

        while (driver.getWindowHandles().size() != numberOfWindows) {

        }
    }

    public static void main(String[] args) throws IOException, InterruptedException {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://localhost:8080/application/index.jsp");

        WebElement gmail = driver.findElement(By.linkText("gmail"));
        WebElement javaTutorial = driver.findElement(By.partialLinkText("Tutorial"));

        String mainWindow = driver.getWindowHandle();
        System.out.println("mainWindow handle " + mainWindow);
        System.out.println("Total handles " + driver.getWindowHandles().size());

        gmail.click();
        waitForNumberOfWindowsToEqual(driver, 2);
        String gmailWindow = driver.getWindowHandle();
        System.out.println("gmailWindow handle " + gmailWindow);
        System.out.println("Total handles " + driver.getWindowHandles().size());

        javaTutorial.click();
        waitForNumberOfWindowsToEqual(driver, 3);
        String javaTutorialWindow = driver.getWindowHandle();
        System.out.println("javaTutorialWindow handle " + javaTutorialWindow);
        System.out.println("Total handles " + driver.getWindowHandles().size());

        driver.quit();
    }
}

输出

mainWindow handle {c0582dd6-8cab-b14c-8820-8d8ef12f8658}
Total handles 1
gmailWindow handle {c0582dd6-8cab-b14c-8820-8d8ef12f8658}
Total handles 2
javaTutorialWindow handle {c0582dd6-8cab-b14c-8820-8d8ef12f8658}
Total handles 3

Answer 1

driver.getWindowHandle();将返回当前焦点窗口的窗口句柄。要获取所有窗口句柄，请使用复数形式的driver.getWindowHandles()

for (String handle : driver.getWindowHandles()) {
    System.out.println(handle);
}

如果您想要最后打开的窗口，您可以每次添加当前窗口列表并按索引

获取

List<String> handles = new List<String>();

// open new window

for (String handle : driver.getWindowHandles()) {
    if (!handles.contains(handle)) { // add the newly opened window
        handles.add(handle);
    }
}

// open the next window and repeat the loop (you can make a method)

handles将按照创建的顺序显示窗口句柄。并获得最后一个windoe

System.out.println("Last handle " + handles.get(handles.size() - 1));

Answer 2

如果打开一个新窗口，窗口的上下文不会改变。即使打开了一个新窗口，方法driver.getWindowHandle()也会返回相同的句柄。要与新打开的窗口进行交互，您必须使用driver.switchTo().window(handle);将上下文设置为目标窗口。

此示例在新窗口上设置上下文，以便驱动程序可以与它进行交互：

WebDriver driver = new ChromeDriver();
WebDriverWait wait = new WebDriverWait(driver, 20);

// open the url
driver.get("http://stackoverflow.com/");

// open a link in a new window with Ctrl + Click
new Actions(driver)
    .keyDown(Keys.CONTROL)
    .click(driver.findElement(By.id("nav-questions")))
    .perform();

// wait for 2 windows
wait.until(ExpectedConditions.numberOfWindowsToBe(2));

// set the context on the new window
Set<String> handles = driver.getWindowHandles();
handles.remove(driver.getWindowHandle());
driver.switchTo().window(handles.iterator().next());

// display the title of the new window
System.out.println("Page title: " + driver.getTitle());

// quit
driver.quit();

请注意，尝试通过获取集的最后一个句柄来获取最后一个窗口 ：

Get Window Handles命令返回每个打开的顶级浏览上下文的窗口句柄列表。返回窗口句柄的顺序是任意的。
