I want to get the URL for my site collection. One way I thought I could do it was using the window.location in javascript and getting it that way.

I know that you can use ECMA script and the client object model to do this but unsure how.

I have tried:

var context = new SP.ClientContext;

This is returning /

How would I get it to include the full URL? i.e. http://mysharepoint:29292/

You can do it without any SharePoint calls by using the default JavaScript location object (W3schools) and the page variable _spPageContextInfo (Ted Pattison's Blog).

Something like:

var url = window.location.protocol + "//" + window.location.host + _spPageContextInfo.siteServerRelativeUrl;

    In my experience despite that this approach will work in a production environment, if you have a large team and you don't control their development environment @Matthias approach is better because it will work even when a developer is working with localhost. sharepoint.stackexchange.com/questions/24817/… Commented Mar 5, 2013 at 1:47

  • Great solution. Although I also needed the path to the current web which your solution didn't really take it all the way. But _spPageContextInfo.webServerRelativeUrl held what I was looking for.

You can do it like this:

function GetSiteUrl()
    var ctx = new SP.ClientContext();
    var site = ctx.get_site();
    ctx.executeQueryAsync(function(s, a){alert(site.get_url())});
<a href='javascript:GetSiteUrl();'>Get site URL</a>

To load only the URL from the site to minimize data traffic you can also call:

ctx.load(site, 'Url');

    Just for John - the difference between normal SP object model programming and the Client object model is that nothing actually happens until ctx.executeQueryAsync - so in previous example you were asking for site properties while it was still 'null' (not strictly null but you get the idea)

  • I had to add this code to Mattias' answer to get this all working: // Call function InitSiteUrl() after SP resources are loaded ExecuteOrDelayUntilScriptLoaded(InitSiteUrl, 'sp.js');

You can do it in Singleline of code

var siteCollectionURL = _spPageContextInfo.siteAbsoluteUrl;

    This is correct for SharePoint 2013, SP2010 _spPageContextInfo does not have the property siteAbsoluteUrl. Commented Feb 20, 2015 at 10:54
function initialize()
       var clientContext = new SP.ClientContext.get_current();
       siteCollec = clientContext.get_site();
       clientContext.executeQueryAsync(Function.createDelegate(this, getUrl), Function.createDelegate(this, getFailed));

function getUrl()
    function getFailed()
       alert('Failed to retrieve the server relative URL.');

For this you can use any of the two:

var url = window.location.protocol + "//" + window.location.host + _spPageContextInfo.siteServerRelativeUrl;

Or we can use

var context = new SP.ClientContext();
var relativeWebUrl = context.get_url();
var fullWebUrl = window.location.protocol + '//' + window.location.host + relativeWebUrl ;

You can use the following:

For Site Collection URL:

var url = window.location.protocol + “//” + window.location.host + _spPageContextInfo.siteServerRelativeUrl;

For Sub Site URL:

var url = _spPageContextInfo.webAbsoluteUrl;

You can use the below code to find WebApp url, this takes care of port number too (if exists)

var WebAppUrl="";
if (location.port)
        WebAppUrl = window.location.protocol + "//" + window.location.host + ":" + location.port;
        WebAppUrl = window.location.protocol + "//" + window.location.host;

I wanted to add another answer here as we've come into the age of the Sharepoint Add-In model and this won't work if you want to get the top level site collection from an Add-In, since you'll either be using a Provider Hosted add-in where your page is hosted off-site or Sharepoint Hosted add-in where it's hosted in the Add-In web. These answers will give you the URL for the Add-In web.

I got the top level site collection url from my Sharepoint Hosted add-in by using the following code:

//Get the URI decoded URLs.
hostweburl =
// Set toplevelurl to the top level site collection url
toplevelurl = hostweburl.split("://")[0] + "://" + hostweburl.split("://")[1].split('/')[0];

Of course if you actually want to take any actions on the top level site collection, remember to use the Cross Domain Library, specifically SP.ProxyWebRequestExecutorFactory and SP.AppContextSite so something like:

clientContext = new SP.ClientContext(addinweburl);
var factory = new SP.ProxyWebRequestExecutorFactory(addinweburl);
topContext = new SP.AppContextSite(clientContext, toplevelurl);

I won't go into using the CDL as that's covered well elsewhere and it's way beyond the scope of this question.

Hope this helps!


No jQuery, no spContext. This can be used on a modern site. Probably needs some tweaking but the idea is to do it using a regex rather than any SharePoint or library provided object.


function getSiteRelativeUrl(urlString) {
  var expr = "/sites/[A-Za-z0-9-]*"

  var match = urlString.match(expr);

  return match;

function getSiteAbsoluteUrl(urlString) {
  var expr = "https://[a-zA-Z.0-9]*"

  var matchFirstPart = urlString.match(expr);
  var relativeUrl = getSiteRelativeUrl(urlString);

    var ret = matchFirstPart + relativeUrl;

  return ret;

var url = "https://mySharePointSite.sharepoint.com/sites/WithumTest-022/sitepages/somepage.aspx"

var relativeUrl = getSiteRelativeUrl(url);
var absoluteUrl = getSiteAbsoluteUrl(url);


Site URL : _spPageContextInfo.siteAbsoluteUrl e.g. "https://site.sharepoint.com/sites/site1"

Page URL window.location.href e.g. "https://site.sharepoint.com/sites/site1/SitePages/Home.aspx"

<script language="javascript">
            function GrabUrl()
                // Custom JavaScript methods
                var currentUrl = document.URL;
