Question

我找不到用于在Facebook中单击注销的正确XPath。
我一直在尝试使用XPath来单击Logout。
谁能帮助我，使用带有Java的Selenium Webdriver单击注销。

代码试用：

//clicking on navigation bar
driver.findElement(By.id("userNavigationLabel")).click();
System.out.println("Successfully clicked");
//Clicking on logout
driver.findElement(By.xpath("//span[contains(text(),'Log out')]")).click();
//closing the current tab
driver.close();

Answer 1

您有任何例外吗？像NosuchElement异常或找不到元素之类的错误。如果是这样，则可以等到元素可见后再执行操作。

public void test_01_Logout()
{
WebDriver driver = new FirefoxDriver(); 
driver.navigate().to("www.facebook.com");   
//Add login code here.
waitForElementInDOM(driver, "//div[@id='userNavigationLabel' and 
contains(text(),'Account Settings')]", 15);
driver.findElement(By.xpath("//div[@id='userNavigationLabel' and 
contains(text(),'Account Settings')]")).click();
waitForElementInDOM(driver, "//span[@class='54nh' and contains(text(),'Log Out')]", 
15);
driver.findElement(By.xpath("//span[@class='54nh' and contains(text(),'Log 
Out')]")).click();
}

public void waitForElementInDOM(WebDriver driver,String elementIdentifier, long 
timeOutInSeconds) 
{       
WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds );
try
{           
//this will wait for element to be visible for 15 seconds       
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath
(elementIdentifier))); 
}
catch(NoSuchElementException e)
{           
e.printStackTrace();
}           
}

要单击文本为注销的元素，您需要使用 WebDriverWait 使元素可点击，并且可以使用以下命令代码行：

driver.findElement(By.cssSelector("div#userNavigationLabel")).click();
new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("//a[contains(@data-gt, 'menu_logout')]/span/span[normalize-space()='Log Out']"))).click();

我可以获取Facebook注销的工作代码吗？
