Utilizing JavaScript to analyze and interact with a website using Selenium's ghost drivers

Currently, I am attempting to scrape the second page of Google search results using Ghost driver. To achieve this, I am utilizing JavaScript to navigate through the HTML source of the search results page and click on the page numbers at the bottom with Ghost driver. However, I encountered an error message as shown below:


import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

driver = new HtmlUnitDriver();

JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("document.querySelectorAll('#foot span div table tbody tr td a')[2].click();");

Exception in thread "main" java.lang.UnsupportedOperationException: Javascript is not enabled for this HtmlUnitDriver instance

Answer №1

Instead of using GhostDriver, consider using HtmlUnit as an alternative. You have two options here. One is to enable JavaScript for HtmlUnit by configuring the desired capabilities of the driver. The other option is to utilize GhostDriver, which is a component of the PhantomJS project. In your Java programming, you would instantiate a PhantomJSDriver object to interact with and navigate through the resulting webpage.
