如何使用 Chrome 扩展程序 API 访问未激活的选项卡的“文档”

Question

我有一个在后台运行 popup.js 的 chrome 扩展程序，每次加载完一个选项卡时 (Chrome Tabs API) 它都会执行一个名为 replaceText.js[ 的脚本=25=]

每次打开新标签时，replaceText.js 都会为 active 和 inactive 标签调用。但是，当我访问 document 时，它总是从 active 选项卡中获取 document。如何从其他选项卡访问 document？

popup.js

chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
  if (changeInfo.status == 'complete' && tab.active) {
    // console.log(tab.title, document);

    chrome.tabs.executeScript(null, {
      file: "replaceText.js"
    }, function() {
    // error
    });
  }
})

replaceText.js

let current_document = document;
// do something with document

manifest.json

{
    "manifest_version": 2,

    "name": "a name",
    "description": "a description",
    "version": "1.0",
    "author": "an author",
    "background": {
        "scripts": ["popup.js"],
        "persistent": true
    },
    "permissions": [
        "tabs",
        "http://*/",
        "https://*/"
    ]
}

作为@wOxxOm mentioned, I needed to replace null with tabId so that the script could know in which tab to run the script, it defaults to the current tab: tabs.executeScript docs。我还必须删除 tab.active 条件，以便它始终可以运行.

chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
  if (changeInfo.status == 'complete') {
    chrome.tabs.executeScript(tabId, {
      file: "replaceText.js"
    }, function() {
    // error
    });
  }
})
