Question

I’m making a chrome package app. Here is my manifest.json

  "app": {
"launch": {
  "local_path": "main.html"
}

"content_scripts": [
{
  "matches": ["http://*/*", "https://*/*", "file://*/*"],
  "js": ["jquery-1.7.min.js", "content_script.js"],
  "all_frame": "true"
}

Why my content script can’t run on main.html? Can content script run on a package app?

Answer 1

Content scripts cannot run at the chrome-extension: protocol ^[1]. For this reason, the content script will not run at your app.

Include the scripts in main.html:

<script src="jquery-1.7.min.js"></script>
<script src="content_script.js"></script>

[1]: The only permitted protocols are http:, https: and file:. For all other protocols, Content scripts will not be injected, even when <all_urls> is specified.
