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

Solution 1:

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);
});

Solution 2:

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
