Question

在我的项目中，我尝试自动创建新员工，因为我需要单击一个链接，该链接将从主窗口打开子窗口，在该子窗口中我需要单击查找按钮，以选择报告该员工的经理。点击该查找后，我得到一个新的孙子窗口，其中包含经理名称列表，以便我可以从中选择一个。

以下是我用来在窗口之间移动的代码，

//从父母移到儿童

    String parentWindow = driver.getWindowHandle();

    Set<String> windowHandles = driver.getWindowHandles();      

    System.out.println(windowHandles.size());

    windowHandles.remove(parentWindow);

   driver.switchTo().window((String) windowHandles.toArray()[0]);

   // Click lookup to emulate Grandchild window
   driver.findElement(..)

   //From child to grandchild

   Set<String> grandChild_Child_ParentHandles=driver.getWindowHandles();

    grandChild_Child_ParentHandles.remove(parentWindow);
    grandChild_Child_ParentHandles.remove(windowHandles);

    System.out.println(grandChild_Child_ParentHandles.size());

    driver.switchTo().window((String) grandChild_Child_ParentHandles.toArray()[0]);

    System.out.println(driver.getTitle());

我的代码一直运行直到单击该查找，之后我的代码停止执行。当代码只有我手动关闭孙子窗口时代码再次启动。我想知道它为什么会发生。

请帮忙！

先谢谢，Siva

由于Modal窗口我遇到了这个问题，可以通过使用多线程概念来解决。通常一旦模态窗口被激发，它将阻止其父窗口，这意味着我们无法将驱动程序移动到新的子窗口。因此，在模态窗口唤起之后，我们的代码停止工作。

尝试引用以下示例代码进行多线程处理，我在网上找到了。

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

class NewThread implements Runnable {
static WebDriver driver = new FirefoxDriver();
Thread t;

NewThread() {
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

// Create a new, second thread
t = new Thread(this, "Demo Thread");
System.out.println("Child thread: " + t);
// Start the thread
t.start();
}

// This is the entry point for the second thread.
public void run() {
try {

System.out.println("This thread has got the control now");
Thread.sleep(5000);

} catch (InterruptedException e) {
System.out.println("Child interrupted.");
}

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

String nextHandle = driver.getWindowHandle();
System.out.println("nextHnadle" + nextHandle);

try {
Thread.sleep(4000);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

driver.findElement(By.id("foo")).clear();
driver.findElement(By.id("foo")).sendKeys("4");
try {
Thread.sleep(2000);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

driver.findElement(By.linkText("link")).click();
try {
Thread.sleep(4000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

driver.quit();
System.out.println("Exiting child thread.");
}

// execution will start from here
public static void main(String args[]) throws InterruptedException {
try {
// open the webpage
driver.get("https://developer.mozilla.org/samples/domref/showModalDialog.html");

// get window handle
String currenthandle = driver.getWindowHandle();
System.out.println("currenthandle" + currenthandle);

//start a new thread
new NewThread();

// click on the button to open model window dialog
driver.findElement(By.tagName("input")).click();

} catch (Exception e) {
System.out.println("Main thread interrupted.");
}
System.out.println("Main thread exiting.");
}

}
