Selenium webdriver Selenium webdriver java下拉列表问题“；元素应该是；选择"；但是是",；分区&引用；

当尝试在Amazon站点中单击注销时，会显示错误消息“Element本应为“select”，但为“div”。在代码末尾，CSS选择器和XPATh标识符中的任何一个都不起作用。请帮助解决此问题

import java.sql.Driver;

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;

public class FirstClass {

    private static final String SeleniumWait = null;

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "C:\\Users\\Documents\\Selenium\\chromedriver_win32\\chromedriver.exe");

        WebDriver driver = new ChromeDriver();

        driver.get("https://www.amazon.com/");
        driver.findElement(By.id("nav-link-accountList")).click();
        driver.findElement(By.id("ap_email")).sendKeys("welcom@gmail.com");
        driver.findElement(By.id("ap_password")).sendKeys("Password");
        driver.findElement(By.id("signInSubmit")).click();
        driver.findElement(By.xpath("//*[@id='nav-link-accountList']/span[1]")).click();
        //driver.findElement(By.xpath("//*[@id='nav-al-container']")).click();
        JavascriptExecutor jse = (JavascriptExecutor)driver;
        jse.executeScript("scroll(0, 50);"); 

        Select dropdown = new Select(driver.findElement(By.xpath("//*[@id='nav-al-container']")));
        dropdown.selectByVisibleText("Not test? Sign Out");
        WebDriverWait wait = new WebDriverWait(driver, 40);// 1 minute 
        wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("//*[@id='nav-item-signout']/span")));
        driver.findElement(By.cssSelector("#nav-item-signout > span")).click();//CSS selector

        //driver.findElement(By.xpath("//*[@id='nav-item-signout']/span")).click(); //XPATH 

在以下行中：

Select dropdown = new Select(driver.findElement(By.xpath("//*[@id='nav-al-container']")));

它只适用于带有

html标记的下拉列表，但在html中它属于

标记。 您需要用不同的方法处理此下拉列表

您需要通过.xpath（“/*[@id='nav-link-accountList']”）将鼠标悬停在

上，而不是使用
操作来单击它

动作动作=新动作（驱动）； action.moveToElement（By.xpath（“/*[@id='nav-link-accountList']）； action.build（）.perform（）；

然后，您需要单击位于by.id（“导航项目签出”）的元素进行签出

Actions action = new Actions(driver); action.moveToElement(By.xpath("//*[@id='nav-link-accountList']")); action.build().perform();
