Chrome扩展程序的内容脚本未注入特定网站

Question

I have developed a basic chrome extension that appends some DOM elements to the website's HTML body. I'm using content scripts to achieve this. It is working fine on most websites, but on few (especially on net-banking websites), content script is not getting executed.

My question is, can a website block content script to inject any code into its webpage (as part of security measure or something)? If so, is there any other alternative? I tried using background script that programmatically executes content scripts, but background script is not getting executed each time a load a new page.

Answer 1

Please make sure if these websites contain iframe. If so, you need to add the following in your manifest.json.

"all_frames": true

Answer 2

Update your manifest.json with below permission

 "content_scripts": [{
                            "matches"       :   ["https://specificURL/*","https://*/*","http://*/*"],
                             "all_frames"   :   true
                        }]
