chrome.webRequest.onCompleted not Found in Content Script

[Georgel]

hello ,

I am creating a chrome extension and I want to monitor current requests in a web page(especially images) .

When I use   chrome.webRequest.onCompleted.addListener(function(details) on the backgroud page it works fine,however when i use the content script to insert in in the current webpage nothing happens, console log shows : Uncaught TypeError: Cannot read property 'onCompleted' of undefined .

It seems I cannot use the webRequest API within the content script? If so,is there a workaroud using javascript to monitor the requests for a webpage ?(After the monitor i need to remove some images from the webpage ,that is why I need to use the Content Script)

Thank you.

Hey,

I'm not so sure this is possible.

According to the documentation: http://developer.chrome.com/extensions/content_scripts.html

However, content scripts have some limitations. They cannot:

• Use chrome.* APIs (except for parts of chrome.extension)

[Scott Fujan]

Correct, content scripts cannot access webRequest. But the docs are wrong; they can also access runtime and storage.

Hello Thank you for your answers .

I may have another question : How can I communicate from the background page of a chrome extension to the Content script of another page ?
