Question

我正在看这个网站：

尝试从我的扩展中注入一个基本的内容脚本，在document_start，它只是在听到DOMContentLoaded事件时登录到控制台。什么都没发生。我查看了很多网站，这通常不是问题。

清单：

"content_scripts": [
    {
      "matches": ["http://*/*", "https://*/*"],
      "exclude_globs": ["*chrome-extension*", "*google*"],
      "js": [ "scripts/page-event-listener.js"],
      "run_at": "document_start"
    },
],

页面事件监听器：

function SendRuntimeMessage(pageStatus) { chrome.runtime.sendMessage({pageStatus: pageStatus}, function() {} ); }
function SendBeforeUnloadMessage() { SendRuntimeMessage("complete"); document.removeEventListener('readystatechange', pageSniffer, false); }

var pageSniffer = function(evt){

  var width = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
  var height = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;
  var screenSize = [width, height];

  if (evt.target.readyState === "loading") { SendRuntimeMessage("loading"); }

  else if (evt.target.readyState === "interactive") {

      chrome.runtime.sendMessage( { pageStatus: "interactive", screenSize: JSON.stringify(screenSize) }, function() {} );

      //setTimeout so we have a hook in cases where the page never hits the complete event, 5 secs to hit it
      setTimeout(function(){

          if (evt.target.readyState === "interactive") { // this stops the timer from firing even when we've reached the 5 seconds, if we've hit the complete event

                SendRuntimeMessage("complete");
                document.removeEventListener('readystatechange', pageSniffer, false);
                window.removeEventListener("beforeunload", SendBeforeUnloadMessage);
          }

      }, 5000);


  }

  else if (evt.target.readyState === "complete") {

        SendRuntimeMessage("complete");
        window.removeEventListener("beforeunload", SendBeforeUnloadMessage);

  }
};

document.addEventListener('readystatechange', pageSniffer, false);
//add an event listener in case the page is unloaded before the timeout or the complete event is hit
window.addEventListener("beforeunload", SendBeforeUnloadMessage);

我查看了网站的来源，我的脚本没有出现在内容脚本列表中。我还注意到该站点报告了服务工作者错误。

我的一般问题是：服务工作者是否应该干扰脚本注入沙箱的操作？有没有人注意到有关服务工作者的事情？这是Chrome错误还是我错过了什么？

扩展，内容脚本，＆＃39; document_start＆＃39;，服务工作者
