content script - Multiple Tab Chrome Extension Issue -


i've created basic extension searches google if url/html content fulfill requirements. works part, fails miserably when there multiple instances of extension. example, if load tab , tab b, click on page action tab a, directed search of tab b's content.

i don't know how silo script each tab, clicking tab a's page action result in search tab stuff. how can done? i'd appreciate suggestions!

background.js

title = ""; luckysearchurl = "http://www.google.com/search?btni=i%27m+feeling+lucky&ie=utf-8&oe=utf-8&q=";  chrome.runtime.onmessage.addlistener(     function(request, sender, sendresponse) {         if (request.title != "") {             title = request.title;             sendresponse({confirm: "we got it."});         }     });  chrome.tabs.onupdated.addlistener(function(tabid, change, tab) {     if (change.status === "complete" && title !== "") {         chrome.pageaction.show(tabid);     } });  chrome.pageaction.onclicked.addlistener(function(tab) {     chrome.tabs.create({url: luckysearchurl + title}) })

contentscript.js

function getsearchcontent() {     url = document.url;     if (url.indexof("example.com/") > -1)         return "example"; }  if (window === top) {     content = getsearchcontent();     if (content !== null) {         chrome.runtime.sendmessage({title: content}, function(response) {         console.log(response.confirm); })   }; }

you store title associated tabid, way when click on pageaction uses correct title. changes these:

background.js

title= [];  [...]  chrome.runtime.onmessage.addlistener(function(request,sender,sendresponse){   if (request.title != "") {     title.push({tabid:sender.tab.id, title:request.title});     sendresponse({confirm: "we got it."});   } });  [...]  chrome.pageaction.onclicked.addlistener(function(tab) {   title.foreach(function(v,i,a){     if(v.tabid == tab.id){       chrome.tabs.create({url: luckysearchurl + v.title});        // here going remove array because otherwise        // array grow without bounds, better remove       // when tab closed can use pageaction more       // once.       a.splice(i,1);     }   }); });
