org.openqa.selenium.support.ui.UnexpectedTagNameException:元素应已被“选择".但“跨度"为在选择下拉值时 [英] org.openqa.selenium.support.ui.UnexpectedTagNameException: Element should have been "select" but was "span" while selecting a dropdown value

问题描述

在这里，我试图使用Selenium脚本从下拉列表中选择一个值，但是在控制台中却出现了此错误，例如

Here I am trying to select a value from dropdown using selenium script but I got this error in the console like

线程主"中的异常" org.openqa.selenium.support.ui.UnexpectedTagNameException:元素应已被选择"，但已被跨度".

"Exception in thread "main" org.openqa.selenium.support.ui.UnexpectedTagNameException: Element should have been "select" but was "span"..

public class HomeUserManagement {

public static void main(String args[]) {
    System.setProperty("webdriver.chrome.driver", 
"C:\\Users\\UMASHANKAR\\Documents\\selenuim\\chromedriver.exe");
    WebDriver driver=new ChromeDriver();
    driver.manage().window().maximize();

//for login
    driver.get("https://ecabportal.azurewebsites.net/dashboard");

driver.findElement(By.name("email")).sendKeys("[e-mail]");

driver.findElement(By.name("password")).sendKeys("abc123xyz");
    driver.findElement(By.name("signIn")).click();  


//actual code for selecting a value from dropdown

 driver.get("https://ecabportal.azurewebsites.net/user");
    Select drpdwn=new Select(driver.findElement(By.id("select2-signup-username-container")));
    drpdwn.selectByVisibleText("User Name");
    drpdwn.selectByIndex(0);

下拉菜单中有多个值，我需要在其中选择一个值.

there are multiple values in a dropdown I need to select one value in that..

推荐答案

此错误消息...

"Exception in thread "main" org.openqa.selenium.support.ui.UnexpectedTagNameException: Element should have been "select" but was "span"

...表示您已使用Select类与所需元素进行交互，因为该元素是<span>.

...implies that you have used Select class to interact with the desired element where as the element was a <span>.

要选择一个值，例如使用下拉菜单中的用户名 您可以使用以下解决方案:

To select a value e.g. User Name from the dropdown using Selenium you can use the following solution:

• 代码块:

• Code Block:

  driver.get("https://ecabportal.azurewebsites.net/dashboard");
  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.name("email"))).sendKeys("[e-mail]");
  driver.findElement(By.name("password")).sendKeys("NsSaNj@0205");
  driver.findElement(By.name("signIn")).click();
  new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//h1[contains(., 'Dashboard')]")));
  driver.get("https://ecabportal.azurewebsites.net/user");
  new WebDriverWait(driver, 20).until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("//div[@id='load']")));
  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("span.select2-selection.select2-selection--single>span.select2-selection__rendered"))).click();
  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//span[@class='select2-results']//li[contains(., 'User Name')]"))).click();

浏览器快照:

Browser Snapshot:

注意:

• 在页面更改(即DOM更改)时尝试click()方法之前，始终为elementToBeClickable()引发 WebDriverWait .
• 在此特定用例中，当您浏览到所需页面时，您需要为[c4>引入 WebDriverWait 然后调用所需的click()的覆盖.

• Always induce WebDriverWait for the elementToBeClickable() before attempting click() method when the page changes i.e. DOM changes.
• In this particular usecase, when you browse to the desired page there is an overlay for which you need to induce WebDriverWait for the invisibilityOfElementLocated() and then invoke the required click().
