Selenium Web自动化中的元素不可交互异常 [英] element not interactable exception in selenium web automation

问题描述

在下面的代码中，我无法在密码字段中发送密码密钥，我尝试单击该字段，清除该字段并发送密钥.但是现在可以使用任何一种方法.但是如果我调试和测试，它就可以工作

In the below code i cannot send password keys in the password field, i tried clicking the field, clearing the field and sending the keys. But now working in any of the method. But its working if i debug and test

  public class TestMail {
   protected static WebDriver driver;

   protected static String result;

   @BeforeClass

   public static void setup()  {
              System.setProperty("webdriver.gecko.driver","D:\\geckodriver.exe");

   driver = new FirefoxDriver();

   driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

  }

   @Test

 void Testcase1() {

   driver.get("http://mail.google.com");

   WebElement loginfield = driver.findElement(By.name("Email"));
   if(loginfield.isDisplayed()){
       loginfield.sendKeys("[e-mail]");
   }
   else{
  WebElement newloginfield = driver.findElemnt(By.cssSelector("#identifierId"));                                      
       newloginfield.sendKeys("[e-mail]");
      // System.out.println("This is new login");
   }


    driver.findElement(By.name("signIn")).click();

  // driver.findElement(By.cssSelector(".RveJvd")).click();

   driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
 // WebElement pwd = driver.findElement(By.name("Passwd"));
  WebElement pwd = driver.findElement(By.cssSelector("#Passwd"));

  pwd.click();
  pwd.clear();
 // pwd.sendKeys("123");
 if(pwd.isEnabled()){
     pwd.sendKeys("123");
 }
 else{
     System.out.println("Not Enabled");
 }

推荐答案

尝试设置大约10秒的隐式等待.

Try setting an implicit wait of maybe 10 seconds.

gmail.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

或设置一个明确的等待.显式等待是您定义的代码，用于等待特定条件发生后再继续执行代码.在您的情况下，这是密码输入字段的可见性. (感谢ainlolcat的评论)

Or set an explicit wait. An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. In your case, it is the visibility of the password input field. (Thanks to ainlolcat's comment)

WebDriver gmail= new ChromeDriver();
gmail.get("https://www.gmail.co.in"); 
gmail.findElement(By.id("Email")).sendKeys("abcd");
gmail.findElement(By.id("next")).click();
WebDriverWait wait = new WebDriverWait(gmail, 10);
WebElement element = wait.until(
ExpectedConditions.visibilityOfElementLocated(By.id("Passwd")));
gmail.findElement(By.id("Passwd")).sendKeys("xyz");

说明:硒无法找到该元素的原因是因为密码输入字段的ID最初是Passwd隐藏的.单击下一步"按钮后，Google首先验证输入的电子邮件地址，然后显示密码输入字段(将ID从隐藏密码"更改为密码").因此，当密码字段仍处于隐藏状态(即Google仍在验证电子邮件ID)时，您的网络驱动程序将开始搜索ID为Passwd且仍处于隐藏状态的密码输入字段.因此，将引发异常.

Explanation: The reason selenium can't find the element is because the id of the password input field is initially Passwd-hidden. After you click on the "Next" button, Google first verifies the email address entered and then shows the password input field (by changing the id from Passwd-hidden to Passwd). So, when the password field is still hidden (i.e. Google is still verifying the email id), your webdriver starts searching for the password input field with id Passwd which is still hidden. And hence, an exception is thrown.
