我对chrome扩展的整个世界都很陌生

我已经阅读了教程“hello world”页面，并试图了解content_脚本和background.html-但我可能服药过量，似乎找不到答案，我确信这是一项简单的任务

在选项卡中，站点包含以下隐藏的HTML：

<div class="XYZ">
<input id="form_ID" type="hidden" value="REF_CODE#Product_CODE#Product Name#">
</div>

弹出窗口需要向内容脚本发送消息，内容脚本收集隐藏字段信息并将响应发送回弹出窗口

以下是一个例子：

popup.html

<html>
<head>
<script>
function readIds() {
    console.log('Send request to content script');
    document.getElementById("response").innerText = "Requesting...";
    chrome.tabs.getSelected(null,function(tab){
        chrome.tabs.sendRequest(tab.id, {cmd: "readIds"}, function(response){
            console.log('Response from page is:' + response);
            document.getElementById("response").innerText = JSON.stringify(response);
        });
    });
}
</script>
</head>
<body style="width:400px;">
<a href="javascript:readIds();return false;">Click to read ids</a>
<pre id="response"></pre>
</body>
</html>

mainfest.json

  // Required

  // Pick one (or none)
  "browser_action": {
    "default_icon": "Foo.png", // optional
    "default_title": "Foo Extension",      // optional; shown in tooltip
    "popup": "popup.html"
    },

  "permissions": [ "http://*/", "https://*/", "tabs" ],

  "content_scripts": [
    {
      "matches": ["http://*/*", "https://*/*"],
      "js": ["content_script.js" ],
      "run_at": "document_idle"
    }
    ]
}

弹出窗口需要向内容脚本发送一条消息，然后内容脚本将收集隐藏字段信息并将响应发送回弹出窗口

以下是一个例子：
