获取隐藏元素的属性

我有一张表，我试图测试。其中一列是yes/no单选按钮，当页面被渲染时，隐藏在图像下方，以便在选择yes或no时有复选标记或X.获取隐藏元素的属性

选择是时单选按钮的属性checked="true"。

我如何使用Selenium2获得该属性，以便我可以对其进行比较或对其进行断言？

我已经尝试过以下，这只会导致空指针错误。

private void verifyPOEligibleYesNull(String driverName) 
{ 
    int min = 1; 
    int max = 6; 
    JavascriptExecutor js = (JavascriptExecutor)driver; 
    StringBuilder stringBuilder = new StringBuilder(); 
    //Navigate to System Facing 
    driver = browser.getDriver(driverName); 
    driver.manage().window().maximize(); 
    driver.navigate().to("http://theURL"); 

    //Enter userName 
    WebElement userName = driver.findElement(By.id("username")); 
    userName.clear(); 
    userName.sendKeys(user); 

    //Enter Password 
    WebElement password = driver.findElement(By.id("pword")); 
    password.clear(); 
    password.sendKeys(pwd); 

    //Click Login 
    WebElement loginBtn = driver.findElement(By.xpath("/html/body/div/div/form/div[3]/div/input")); 
    loginBtn.click(); 
    try 
    { 
     Thread.sleep(5000); 
    } 
    catch (InterruptedException e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    WebElement ivToPoBtn = driver.findElement(By.xpath("/html/body/div/div/div/ul/li/a/img")); 
    ivToPoBtn.click(); 
    try 
    { 
     Thread.sleep(5000); 
    } 
    catch (InterruptedException e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    //Grab a random row and determine whether the PO Eligible is "Yes" 
    String rowNum = Integer.toString(rand.nextInt(max - min + 1) + min); 
    WebElement randomRow = driver.findElement(By.xpath("/html/body/div/div/div/div/form/div/div[2]/div/div[2]/div/div/div/div/div/div/div/table/tbody/tr["+rowNum+"]/td/div/div/input")); 
    String poEligibleChecked = randomRow.getAttribute("checked").toString(); 
    stringBuilder.append("var x = $(\""+poEligibleChecked+"\");"); 
    stringBuilder.append("return x.toString();"); 
    String res = (String) js.executeScript(stringBuilder.toString()); 
    System.out.println(res);  
}

我甚至试过这是从WebDriver FAQ建议如下：

WebElement randomRow = driver.findElement(By.xpath("/html/body/div/div/div/div/form/div/div[2]/div/div[2]/div/div/div/div/div/div/div/table/tbody/tr["+rowNum+"]/td/div/div/input")); 
    String poEligibleChecked = randomRow.getAttribute("checked"); 
    String element = js.executeScript("return arguments[0].getText();", poEligibleChecked).toString(); 
    System.out.println(element);

类似的空指针异常错误。

你的代码没有意义。为了得到一种无形要素的checked属性，只需使用element.getAttribute()：

final String scriptGetChecked = "return arguments[0].getAttribute('checked')"; 

WebElement randomRow = driver.findElement(By.whatever("something")); 
String checkedState = (String) js.executeScript(scriptGetChecked, randomRow);

我仍然得到了'NullPointerException'当我试图你有什么上面。我得到的例外是最后一个，我运行'JavaScriptExecutor' – DarthOpto

这是行得通的，谢谢你的帮助。 – DarthOpto
