在硒中发现StaleElementReferenceException

Question

在这里，我尝试在印度输入cpa，然后在列表中收集带有广告的网址，然后单击不是来自Miles Education域的网址。但是我收到了StaleElementReferenceException。

请帮助我解决问题。 这是代码。

package com.MilesEducation.googleSearch;

import java.util.List;

import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;


public class GoogleSearch
{
    public static void main(String[] args) throws InterruptedException 
    {
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.google.com/");
        driver.manage().window().maximize();
        
        WebElement searchbox = driver.findElement(By.xpath("//input[@name=\"q\"]"));
        
        Actions a = new Actions(driver);
        a.moveToElement(searchbox).sendKeys("cpa in india").sendKeys(Keys.ENTER).build().perform();
        Thread.sleep(1000);
        
        List<WebElement> adlinks = driver.findElements(By.xpath("//a[@class='Krnil']"));
        
        
        for(int i=0;i<adlinks.size();i++)
        {
            //WebElement link = adlinks.get(i);
        
            WebElement link = adlinks.get(i);
            String linknames = adlinks.get(i).getAttribute("href");
            System.out.println(linknames);
            
            
            String miles = "mileseducation";
            if(linknames.contains(miles))
            {
                
            }
            else
            {
                
                link.click();
                Thread.sleep(10000);
                JavascriptExecutor js = (JavascriptExecutor) driver;
                js.executeScript("window.scrollTo(0, document.body.scrollHeight)");
                //driver.quit();
                
                
            
            }
            
            
        }
        
        
    }
    
}
