runtime ref:

  • Extension code (包含Background Pages): 可以访问全部chrome.* API
  • Content scripts
    • 有两种加入途径
      • manifest.json中的content_scripts字段
      • chrome.tabs.executeScript
    • 访问权限：
      • 可以访问部分chrome.* API
      • 可以访问全部 DOM
      • 不能访问window对象，也不能访问任何 frame
  • Injected scripts

Run content scripts both in new pages/tabs and iframes

By default, when http://abc.com/ifram/test.html page was in a frame of a page, the content scripts will not run.

You could use all_frames switch to make sure content scripts running in all pages, and also frames.

  "content_scripts": [
    {
      "matches": ["http://abc.com/ifram/test.html"],
      "all_frames": true,
      "js": [
        "fill.js"
      ]
    },
