How to fetch URL of current Tab in my chrome extension using javascript

I am just getting started with Google Chrome Extension development and my project involves making an extension which when clicked prints the URL of whichever page/tab is currently open.

So if I am on google's home page and I click my extension, I need to get "https://www.google.com/" as my output within the extension.

I need to do this using javascript and am unable to find code which I understand and which does the job. I read about using "window.location" and "document.href" and stuff but won't that give me the url of just my extension and not the current tab?

Please help me get started. Thanks in advance.

Update : If you are on manifest version 3 then proceed with the following,

 async function getCurrentTab() {
 let queryOptions = { active: true, currentWindow: true };

  let [tab] = await browser.tabs.query(queryOptions);
  localStorage.setItem('tabname' , tab);
   return tab;
  }

 getCurrentTab()
 .then((data) => { console.log('newdata',data)})
 .then(() => { console.log('error')});

Note you must have the tabs permission set in your manifest file

"permissions": [
    "tabs"
],

http://developer.chrome.com/extensions/tabs.html

or the activeTab permission if initiated by a click on the extension button[Xan]

https://developer.chrome.com/extensions/activeTab

Code:

chrome.tabs.query({currentWindow: true, active: true}, function(tabs){
    console.log(tabs[0].url);
});

Please be aware that chrome.tabs.query() and chrome.tabs.getCurrent will run into race conditions when called in short order from multiple content scripts.

The returned tab will not necessarily be the tab of the requestor.

An easier way to do this is to send a message to the background thread. This message includes the sending tab as the tab parameter.

The background thread can take this parameter and directly include it in its response to the message.

Not only does this prevent race conditions, it's also faster because it does not use an asynchronous operation (unlike the call to chrome.tabs.query())

Example:

Content script

var myTab;
chrome.runtime.sendMessage({ message: "get_tab_msg" }, (response) => {
    myTab = response.tab;
});

Background script

chrome.runtime.onMessage.addListener((request, sender, sendResponse) => {
    if (request.message === "get_tab_msg") {
        // The content script has asked for the tab.
        sendResponse({tab: sender.tab});
    }
});

let currentURL = window.location.href;
console.log(currentURL)

Here is the answer your looking for without adding new tabs permissions

chrome.browserAction.onClicked.addListener(function(e){
     console.log(e.url); 
     //give you the url of the tab on which you clicked the extension
})

DO NOT use getSelected

As per the Chrome Developer Docs: chrome.tabs.getSelected has been deprecated since Chrome ver.33

Instead use:

chrome.tabs.query({active:true}, __someCallbackFunction__) like Musa's second suggestion.

You need to be careful with what you mean by "current tab". If the user has more than one window open, each of them with multiple tabs, Chrome defines the "current window" as the one that is running the content script that makes use of the chrome.tabs API. That happened to me and I solved it by referencing not the "current" window but the last focused one:

chrome.tabs.query({ active: true, lastFocusedWindow: true }, function (tabs) {
    // Do something
});

References:

https://developer.chrome.com/extensions/windows#current-window https://developer.chrome.com/extensions/tabs#method-query

Hope it helps!

this worked for me give it a try 

chrome.tabs.query({
active: true,
lastFocusedWindow: true
}, function(tabs) {
// and use that tab to fill in out title and url
var tab = tabs[0];
console.log(tab.url);
alert(tab.url);
 });

UPDATE: this method is now deprecated, so please don't use it

In my case any above has not worked. So I used this:

chrome.tabs.getSelected(null, function(tab) {
    console.log(tab.url)
})

and it worked great! Hope it helps.

Using javascript, it will work if you are not using it in popup because javascript in popup will return url of popup therefore, in popup, you have to use Chrome tab API and set permission in Chrome manifest.

chrome.tabs.query({currentWindow: true, active: true}, function(tabs){
    console.log(tabs[0].url);
});

So best way is to use Chrome tab API
