如何调试Google Chrome后台脚本？ [英] How to debug Google Chrome background script?

问题描述

我有非常简单的扩展名：

I have very simple extension:

manifest.json

manifest.json

{
  "name": "historyCleaner",
  "version": "0.1.1",
  "manifest_version": 1,
  "description": "This is my first Chrome extension",
  "background": {
    "scripts": ["cleaner.js"]
  }, 
  "permissions": [
    "history"
  ]
}

clean.js

chrome.history.onVisited.addListener(function(HistoryItem result) {

  console.log("it works!");
  alert("it works!");

});

我已经将其加载到Google Chrome中，它已打开，...它没有工作。它不会在控制台中记录任何东西，它不会发出任何警告，更糟糕的是，我无法在开发人员工具脚本选项卡中找到它。我如何找到为什么它不起作用？

I've loaded it in Google Chrome, it is turned on and... it doesn't work. It doesn't log anything in console, it doesn't alert anything and what is worse, I can't find it in developers tools "Scripts" tab. How can I find why it doesn't work?

//编辑

我已经改变了清单。 json到这一个：

I've changed manifest.json to this one:

{
  "name": "historyCleaner",
  "version": "0.1.5",
  "manifest_version": 1,
  "description": "This is my first Chrome extension",
  "background_page": "background.html",
  "permissions": [
    "history",
    "background"
  ]
}

并将JavaScript嵌入到background.html

And embeded JavaScript in background.html

推荐答案

，如果您的 console.log （it works！）; 不显示，那意味着 chrome.history.onVisited 尚未触发。

and also if your console.log("it works!"); does not show up, then that's mean chrome.history.onVisited is not fired yet.

ps：对于函数（HistoryItem结果），您可能需要将其更改为 function（result） 。

ps: For function(HistoryItem result), you may want to change it to function(result).
