Embedding javascript for parsing and clicking a webpage in selenium ghost drivers

Question

I am trying to parse Google search result page with Ghost driver, for which I need to parse the second search result page. So using Java script, I am trying to go through the source (html) of search result page and navigating by clicking(with Ghost driver) the page numbers below it. Then it throws following Exception.

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

That's not using GhostDriver; that's using HtmlUnit. You have two choices. You can either enable JavaScript for HtmlUnit, which would be done through the desired capabilities of the driver, or you can actually use GhostDriver, which is a part of the PhantomJS project. In your Java code, you'd create a PhantomJSDriver object, which would be used to navigate to manipulate the resulting page.
