onUpdated，onActivated不起作用 - chrome扩展

Question

我正在学习编写JavaScript扩展，并选择了一个基本的应用程序。我正在编写的扩展名只是在每个链接中添加了属性target='_blank'。单击图标后激活扩展程序。它工作得很好，但我正在添加监听器来更新，替换和激活事件，而且它们都没有工作。已经检查了一些SO帖子，但它没有帮助（比如说this，this等等）。用Google搜索到达饱和点并发布问题。请帮忙。

这是我的代码。

background.js

chrome.browserAction.onClicked.addListener(function(tab){
  chrome.storage.local.get('click',function(result){
    if(result.click == 0){
        chrome.storage.local.set({"click":1},function(){
        mainProc(tab.id,result.click);
        });
    } else if (result.click == 1) {
        chrome.storage.local.set({"click":0},function(){
        mainProc(tab.id,result.click);
        });
    } else if (result.click == undefined) {
      chrome.storage.local.set({"click":1},function(){
      mainProc(tab.id,result.click);
      });
    }
  })
});

chrome.tabs.onActivated.addListener(function(activeInfo){
  chrome.storage.local.get("click",function(result){
    if(result.click == 1){
      mainProc(activeInfo.tabId,result.click);
    }
  })
})

chrome.tabs.onUpdated.addListener(function(tabid,changeInfo,tab) {
  if(changeInfo.status == "complete"){
    chrome.storage.local.get("click",function(result){
      if(result.click == 1){
      chrome.tabs.query({active:true,currentWindow:true},function(tabs){
        mainProc(tabs[0].id,result.click);
      });
      }
    })
  }
})

chrome.tabs.onReplaced.addListener(function(addedTabId,removedTabId){
  chrome.storage.local.get("click",function(result){
    if(result.click == 1){
      mainProc(addedTabId,result.click); //tried with removedTabId too, just to be sure
    }
  })
})

function changeIcon(clicked){
  if(clicked == 1){
    chrome.browserAction.setIcon({path: 'light.png'});
  }else {
    chrome.browserAction.setIcon({path: 'dark.png'});
  }
}

function activate(id){
  chrome.storage.local.get("click",function(result){
    if(result.click == 1){
      mainProc(id,result.click);
    }
  })
}

function clickListener(id){
  chrome.storage.local.get("click",function(result){
    if (result.click == 0) {
      chrome.storage.local.set({"click":1},function(){
        mainProc(id,result.click);
      });
    } else if (result.click == 1) {
      chrome.storage.local.set({"click":0},function(){
        mainProc(id,result.click);
      });
    } else if (result.click == null) {
      chrome.storage.local.set({"click":1},function(){
        mainProc(id,result.click);
      });
    } else if (result.click == undefined) {
      chrome.storage.local.set({"click":1},function(){
        mainProc(id,result.click);
      });
    }
  })
}

function mainProc(id,click){
  changeIcon(click);
  chrome.tabs.sendMessage(id,{clicked:click});
}

的script.js

chrome.runtime.onMessage.addListener(function(msg,sender){
  var a = document.getElementsByTagName("a");
  if(msg.clicked == 1){
    console.log("clicked:",msg.clicked);
    for(var i = 0;i<a.length;i++){
      a[i].setAttribute("target","_blank");
      a[i].className += " newtab";
    }
  } else if (msg.clicked == 0) {
    console.log("clicked:",msg.clicked);
    for(var i = 0;i<a.length;i++){
      if(a[i].classList.contains("newtab")){
        a[i].classList.remove("newtab");
        a[i].removeAttribute("target");
      }
    }
  }
});
