Java 硒日历用户界面处理

Iam正在学习selenium中的日历UI处理概念，但仍然存在问题 代码1:

import java.util.concurrent.TimeUnit;

enter code here

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class CalenderUI {

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver","C:\\Users\\sumit goyal\\Downloads\\chromedriver_latest\\chromedriver.exe");

        WebDriver driver = new ChromeDriver();
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.manage().window().maximize();
        driver.get("http://www.airindia.in/");
        driver.findElement(By.cssSelector("li.bookFlight")).click(); //CALENDER Resides inside it

        driver.findElement(By.xpath("//input[@title='Departing']")).click(); // will open calendar POPUPmenu

        WebElement cal = driver.findElement(By.xpath("//div[@id='ui-datepicker-div']/div[2]")); //restricting scope

        while(!(driver.findElement(By.cssSelector("div[class='ui-datepicker-title'] span:nth-child(2)")).getText().equals("2021")))

        {
            cal.findElement(By.cssSelector("a[data-handler='next']")).click(); //will click on next button until 2021 arrives

        }

    }

}

运行代码后，我得到了以下错误：过时元素引用：元素未附加到页面文档

每个选择器似乎都是正确的，我检查了它，我不明白为什么它会失败

如果页面上发生的DOM操作暂时导致元素无法访问，则可能会发生这种情况。考虑到这些情况，您需要尝试在循环中重新定位元素

替换以下代码：

driver.findElement(By.xpath("//input[@title='Departing']")).click(); // will open calendar POPUPmenu
while (!(driver.findElement(By.cssSelector("div[class='ui-datepicker-title'] span:nth-child(2)")).getText().equals("2021"))) {
    WebElement cal = driver.findElement(By.xpath("//div[@id='ui-datepicker-div']/div[2]")); //restricting scope
    cal.findElement(By.cssSelector("a[data-handler='next']")).click(); //will click on next button until 2021 arrives
}
