Is there a reason for the inability to deactivate JavaScript in GhostDriver/PhantomJSDriver?

Is there a way to turn off JavaScript in PhantomJSDriver for only one page? I found this link that says it's not possible because it will make the whole GhostDriver unusable.

Could you explain why this happens in a simple way, like I'm just 5 years old?

Are there any other options to stop PhantomJSDriver from running JavaScript on a specific page?

Answer №1

GhostDriver, a JavaScript-based tool, utilizes the PhantomJS API to interpret WebDriver wire protocol commands into native PhantomJS commands/calls.

In PhantomJS, there are two distinct contexts: the outer (phantom) context for controlling the browser and the inner (page) context where page JavaScript is run. Disabling JavaScript in PhantomJS only affects the page context, limiting functionality such as page.evaluate*(), which accesses the page context. The lack of DOM-related functions in the PhantomJS API means you cannot interact with elements on the page - no element location, text retrieval, modification, or clicking capabilities.

The only actions available are capturing screenshots (page.render()) and blind clicking/typing (page.sendEvent()), which fall short of meeting the requirements of the WebDriver protocol.
