org.openqa.selenium.support.ui.UnexpectedTagNameException:元素应该是“选择"；但是是“跨度"在选择下拉值时

在这里，我尝试使用 selenium 脚本从下拉列表中选择一个值，但我在控制台中收到此错误，例如

<块引用>

线程main"中的异常 org.openqa.selenium.support.ui.UnexpectedTagNameException:元素应该是select"，但是是span"..

公共类 HomeUserManagement {公共静态无效主要(字符串参数[]){System.setProperty("webdriver.chrome.driver","C:\Users\UMASHANKAR\Documents\selenuim\chromedriver.exe");WebDriver driver=new ChromeDriver();driver.manage().window().maximize();//用于登录driver.get("https://ecabportal.azurewebsites.net/dashboard");driver.findElement(By.name("email")).sendKeys("abc@xyz.in");driver.findElement(By.name("password")).sendKeys("abc123xyz");driver.findElement(By.name("signIn")).click();//从下拉列表中选择值的实际代码driver.get("https://ecabportal.azurewebsites.net/user");Select drpdwn=new Select(driver.findElement(By.id("select2-signup-username-container")));drpdwn.selectByVisibleText("用户名");drpdwn.selectByIndex(0);

下拉列表中有多个值，我需要在其中选择一个值..

解决方案

这个错误信息...

线程main"中的异常org.openqa.selenium.support.ui.UnexpectedTagNameException:元素应该是选择"；但是是跨度"

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

选择一个值，例如用户名使用

注意:

• 当页面发生变化(即 DOM 发生变化)时，在尝试 click() 方法之前，始终为 elementToBeClickable() 引入 WebDriverWait.
• 在这个特定的用例中，当您浏览到所需的页面时，您需要为 invisibilityOfElementLocated() 诱导 WebDriverWait 的覆盖，然后调用所需的click().

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

"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("abc@xyz.in");

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);

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

解决方案

This error message...

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

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

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

• Code Block:

    driver.get("https://ecabportal.azurewebsites.net/dashboard");
    new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.name("email"))).sendKeys("admin@malbork.in");
    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();
  

• Browser Snapshot:

---

Note:

• 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().
