我编写了一个脚本并收到了一个过时的元素错误。我知道问题出在哪里，但我不知道如何修复脚本。

我正在编写一个脚本来通过 FireFox 执行以下操作：1），启动 google.com，2），输入“pluralsight”，3），提交，4），单击图像链接。

除了选择图像链接之外，我能够执行每个步骤。当我检查错误时，看起来 ide 正在搜索位于谷歌主页上的图片链接，而不是在谷歌上搜索后出现的图片链接（我希望这是有道理的）。这是脚本：

enter code here
package com.pluralsight;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class WebDriverTutorial {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        //System.setProperty("webdriver.gecko.driver", "C:\\Program Files(x86)\\Drivers\\Gecko\\geckodriver.exe");

        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.google.com");
        WebElement searchfield = driver.findElement(By.name("q"));

        searchfield.sendKeys("pluralsight");
        searchfield.submit();

        WebElement imagesLink= driver.findElements(By.linkText("Images")).get(0);
        driver.navigate().refresh();
        imagesLink.click();

脚本和错误的快照

我很感激帮助。谢谢！

下面的图片是我想要得到的：

预期的最终结果

实际结果如下（不带driver.navigate().refresh()）：

实际最终结果 1

并与driver.navigate().refresh()：

实际最终结果 2

以下是错误日志：

使用上图，最终发生的是在搜索栏中出现“pluralsight”之后，页面不提交（意味着它不搜索）。相反，它会刷新（导致搜索栏清空），然后从主页中选择“图像”链接。
