Question

URL http://letskodeit.teachable.com/pages/practice中有一个名为打开窗口的按钮元素。

我可以检查名为“ openwindow”的元素按钮。我尝试为此元素使用“ id”和“ xpath”。但错误显示“找不到元素”。我有隐性的等待。我可以检查名为“ openwindow”的元素按钮。我尝试为此元素使用“ id”和“ xpath”。但错误显示“找不到元素”。我有隐式的等待。

我添加了显式等待和achromeDriver.get(baseUrl);方法来启动URL。下面的代码对我有用。

import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;     

public class WindowHandles {

   private WebDriver achromeDriver;
   private String baseUrl;   

   @Before
   public void setUp() throws Exception {  

          baseUrl = "http://letskodeit.teachable.com/pages/practice";           
          System.setProperty("webdriver.chrome.driver", 
"C:\\Selenium\\ChromeDirver\\chromedriver.exe");             

          achromeDriver = new ChromeDriver();               
          achromeDriver.get(baseUrl);


          achromeDriver.manage().window().maximize();   

          System.out.println("setup completed");
   }    

   @Test

   public void test() throws InterruptedException {   // Get the handle

          String parentHandle = achromeDriver.getWindowHandle();
          System.out.println("Parent Handle: " + parentHandle);                
          WebDriverWait w= new WebDriverWait(achromeDriver, 10);
          WebElement openWindow = 
 achromeDriver.findElement(By.xpath("//button[@id='openwindow']")); 
          w.until(ExpectedConditions.elementToBeClickable(openWindow));
          // Find Open Window button                
         System.out.println("before finding the element");                              

          openWindow.click();    

          // Get all handles

          Set<String> handles = achromeDriver.getWindowHandles();    

          // Switching between handles

          for (String handle: handles) {
                 System.out.println(handle);

          }
          // Switch back to the parent window

   }



   @After

   public void tearDown() throws Exception {

   }

}

Answer 2

要在文本为打开窗口的元素上click()，您必须为elementToBeClickable()引入 WebDriverWait ，并且您可以使用跟随Locator Strategies：

cssSelector：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("button#openwindow"))).click();

xpath：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//button[@id='openwindow']"))).click();

Selenium Webdriver用ID搜索时找不到按钮元素
