Change the URL in chrome after the page has loaded -

-

i've written following script change url of tab in chrome, can't figure out how automatically run on every page.

  var nytimes = /.*nytimes\.com.*/;   var patt = /(&gwh=).*$/;    function updateurl(tab){    if(tab.url.match(nytimes))    {     var newurl = tab.url.replace(patt,"");     chrome.tabs.update(tab.id, {url: newurl});    }   }  chrome.tabs.onupdated.addlistener(function(tab) {updateurl(tab);});

i put background page, isn't working. need put code somewhere else run?

i suggest read content scripts. you're looking need understand have limited access chrome.* api, you'll have use message passing in order use current functionality. however, using content scripts can make simpler using 1 of proposed solutions.

solution 1

assuming want send redirect same url every time, can configure extension run content script on ny times site. example;

content script: content.js

location = 'http://example.com';

solution 2

however, if redirect url can vary many want abstract logic in background page. example;

content script: content.js

// or can pass more specific section of url (e.g. `location.pathname`) chrome.extension.sendrequest({href: location.href}, function(data) {   location = data.url; });

background page: background.js

chrome.extension.onrequest.addlistener(function(request, sender, sendresponse) {   sendresponse({     url: geturl(request.href) // todo: `geturl` method containing logic...   }); });

important!

regardless of approach go need request permission run content script on target site in manifest file.

manifest: manifest.json

{   ...   "content_scripts": [     {       "js": ["content.js"],       "matches": ["*://*.nytimes.com/*"],       "run_at": "document_start"     }   ],   ... }
