尝试从Google搜索编辑框获取并打印数据，但收到InvalidElementStateException

Question

我正在尝试在Google搜索编辑框中写一个字并捕获所有相关列表项并显示它。但是在这样做的时候，我得到了一个异常org.openqa.selenium.InvalidElementStateException：元素被禁用，因此可能无法用于操作。我经历了相同的异常相关问题，并根据他们更改了我的代码，但是它们都没有帮助。

import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;

public class AutoIt {
 public static void main(String[] args){
  WebDriver window;
  FirefoxProfile profile = new FirefoxProfile();
  profile.setEnableNativeEvents(false);
  window = new FirefoxDriver(profile);
try{
window.get("https://www.google.co.in/");
window.manage().window().maximize();
window.findElement(By.id("gs_htif0")).sendKeys("Shantanu Nandan");
window.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);
List<WebElement> list=window.findElements(By.xpath("//td[@style='width: 100%;']/span"));
window.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);
for(WebElement data:list){
    System.out.println(data.getAttribute("value"));
 }//for
}//try
catch(Exception e){
System.out.println("Got a exception");
    e.printStackTrace();
    window.close();
}//catch
finally{
    System.out.println("Finally Block Executed ....");
    window.close();
    window.quit();
}//finally
  }//main
}//class

我为此代码得到的异常

Answer 1

您选择了错误的元素。

使用下面的一个搜索文本框

wb=window.findElement(By.name("q"));

使用以下内容获取输出建议。

List<WebElement> list = window.findElements(By.className("gsq_a"));

要从列表中获取值，请使用getText（）方法而不是getAttribute（）。

for (WebElement data : list) {
System.out.println(data.getText());
}
