想要在地址栏值发生变化时以chrome方式触发事件

Question

我对Chrome进行了扩展，以阻止广告。但有个问题。每当我将地址栏的值从www.flipkat.com更改为www.snapdeal.com时，我的adblock都会显示两个网址上阻止的广告组合数量。对于同一个tabId，如果我在地址栏中更改了我的网址，则会显示在同一个标​​签中输入的所有网址的合计计数。

是否有一个函数可以在每次更改地址栏中的URL时使计数无效？

这是我的代码........

var FilterNotifier = require("filterNotifier").FilterNotifier;
var newURL = [];
var temp1 = [];
var onFilterChangeTimeout = null;
function onFilterChange()
{
  onFilterChangeTimeout = null;
  ext.webRequest.handlerBehaviorChanged();
}

var importantNotifications = {
  'filter.added': true,
  'filter.removed': true,
  'filter.disabled': true,
  'subscription.added': true,
  'subscription.removed': true,
  'subscription.disabled': true,
  'subscription.updated': true,
  'load': true
};

FilterNotifier.addListener(function(action)
{
  if (action in importantNotifications)
  {
    // Execute delayed to prevent multiple executions in a quick succession
    if (onFilterChangeTimeout != null)
      window.clearTimeout(onFilterChangeTimeout);
    onFilterChangeTimeout = window.setTimeout(onFilterChange, 2000);
  }
});

function onBeforeRequest(url, type, tab, frame)
{
  if (isFrameWhitelisted(tab, frame))
    return true;

  var docDomain = extractHostFromURL(frame.url);
  var filter = defaultMatcher.matchesAny(
    url,
    type == "sub_frame" ? "SUBDOCUMENT" : type.toUpperCase(),
    docDomain,
    isThirdParty(extractHostFromURL(url), docDomain)
  );

  //FilterNotifier.triggerListeners("filter.hitCount", filter, 0, 0, tab);
  //return !(filter instanceof BlockingFilter);

  if(filter instanceof BlockingFilter){
    try{
    if(newURL[tab._id]==undefined){
        var urls = []
        urls.push(extractHostFromURL(url))
        newURL[tab._id]=urls
    }else if(newURL[tab._id]!=undefined &&newURL[tab._id].length >0){
        //alert("suresh")
        temp1 = newURL[tab._id];
        temp1.push(extractHostFromURL(url))
        newURL[tab._id]=temp1
    }
    }catch(e){}
    //alert(newURL)
    return false;
  }else if(!filter instanceof BlockingFilter){
    return true
  }
}

/*function  UniqueArray (newURL,tabId)

           }
