回答1:

You can implement this feature using the onBeforeRequest event of the webRequest API. Create a filter with type: ['sub_frame'], and extraInfoSpec ['blocking']. Then, return {cancel:true} in the event listener.

Minimal example:

chrome.webRequest.onBeforeRequest.addListener(function(details) {
    // Save the data in `details` for later use
    // The data must be associated with the `tabId` and `frameId`, so that it
    //  can be used later
    if (your_method_says_block_it())
       return {cancel: true};
}, {
    urls: ['*://*/*'],
    types: ['sub_frame']
}, ['blocking']);

Manifest file:

 ...
    "permissions": ["webRequest", "webRequestBlocking", "*://*/*"]
 ...

• The webRequest permission is needed to enable the API.
• The webRequestBlocking permission is needed to make the request handling synchronous, to enable the function to modify (cancel) the request.
• The *://*/* permission is needed to allow access to the host
