Get current URL from within a chrome.contextMenus.onClicked listener

Question

I\'m creating my first Chrome extension and I need some help. I I think everything is working except the fact that I can\'t get the current URL of the tab.

var m         


        

Answer 1

Function:

function getCurrentUrl(callBackFuntion){
//you are in content scripts
    if(null == chrome.tabs || null == chrome.tabs.query){
        callBackFuntion(document.location.href);
    }else{
//you are in popup
        var queryInfo = {
            active: true, 
            currentWindow: true
        };
        chrome.tabs.query(queryInfo, function(tabs) {
            var tab = tabs[0]; 
            callBackFuntion(tab.url);
        }); 
    }
}

Function call:

function alertUrl(url){
    console.log("currentUrl : " + url);
}
getCurrentUrl(alertUrl);

Answer 2

chrome.tabs.getCurrent(function(tab){
    alert(tab.url);
});

OR if you're in a content script,

alert(document.location.href);

The info you require are provided to you already in the callback of the onClicked listener.

chrome.contextMenus.onClicked.addListener(function(info, tab) {
    // The URL of the tab (if any)
    var tabURL = tab && tab.url;

    // The URL of the page (if the menu wasn't triggered in a frame)
    var pageURL = info.pageUrl;

    // The URL of the frame (if the menu was triggered in a frame)
    var frameURL = info.frameUrl;

E.g. you could achieve what you want like this:

manifest.json:

{
    "manifest_version": 2,
    "name":    "Test Extension",
    "version": "0.0",

    "background": {
        "persistent": false,
        "scripts": ["background.js"]
    },

    "permissions": ["contextMenus"]
}

background.js:

var baseURL = 'http://example.com/';

chrome.contextMenus.create({
    id: 'myMenu',   // <-- event-pages require an ID
    title: 'Do cool stuff',
    contexts: ['all']
}, function () {
    /* It is always a good idea to look for errors */
    if (chrome.runtime.lastError) {
        alert('ERROR: ' + chrome.runtime.lastError.message);
    }
});

chrome.contextMenus.onClicked.addListener(function(info, tab) {
    /* Check which context-menu was triggered */
    if (info.menuItemId === 'myMenu') {
        /* Get the URL of the frame or (if none) the page */
        var currentURL = info.frameUrl || info.pageUrl;

        /* Open a new tab */
        chrome.tabs.create({
            url: baseURL + encodeURI(currentURL)
        });
    }
});

If you are using content script you can use

document.location.href

document.location is Object and can provide set of useful chunks in the URL

• document.location.host returns domain name ex: "http://www.google.com/"
• document.location.path returns the part after the domain name
• document.location.hash returns whatever after # symbol in the url
