陈旧元素Selenium和Java的JSON状态映射

Question

我写了一个脚本，收到了一个陈旧的元素错误。我知道问题是什么，但我不知道如何修复脚本

我正在编写一个脚本，通过FireFox执行以下操作：1）启动谷歌。com，2），输入“pluralsight”，3），提交，4），点击图片链接

除了选择图片链接，我可以执行每一步。当我检查错误时，似乎ide正在搜索位于谷歌主页上的图像链接，而不是点击谷歌搜索后出现的图像链接（我希望这是有意义的）。以下是脚本：

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();

Snapshot of script and error

谢谢你的帮助。谢谢

Answer 1

下面的图片是我想要得到的：

Expected End Result

实际结果如下（无driver.navigate().refresh()）：

Actual End Result 1

和driver.navigate().refresh()

Actual End Result 2

在上面的图片中，当“pluralsight”出现在搜索栏中后，页面不会提交（这意味着它不会搜索）。相反，它会刷新（导致搜索栏清空），然后从主页上选择“图像”链接
