  1. POASP.NET Facebook Connect Confusion: Property 'open' of object [object DOMWindow] is not a function

    copied!<p>I am trying to implement Facebook Connect functionality into a website that I am working on. The site uses ASP.NET, a master page that wraps every existing page (including my login page) and Ajax Control Toolkit for some controls. I am using JavaScript SDK functions as the Facebook Documentation dictates. Here is the code to call Facebook API:</p> <pre><code>`&lt;div id="fb-root"&gt; &lt;/div&gt; &lt;script type="text/javascript"&gt; (function (d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_GB/all.js#xfbml=1&amp;appId=APP_ID"; fjs.parentNode.insertBefore(js, fjs); } (document, 'script', 'facebook-jssdk')); &lt;/script&gt;` </code></pre> <p>And here is the code that supplies users an entry point to Facebook Login with an anonymous JavaScript function:</p> <pre><code>&lt;input type="button" onclick=" FB.login(function(response) { if (response.authResponse) { console.log('Welcome! Fetching your information.... '); FB.api('/me', function(response) { console.log('Good to see you, ' + response.name + '.'); FB.logout(function(response) { console.log('Logged out.'); }); }); } else { console.log('User cancelled login or did not fully authorize.'); } }, {scope: 'email'});" value="Login Facebook" /&gt; </code></pre> <p>The problem is that I get an exception saying that window.open is not a function but a property of the object and the Facebook Login dialog won't appear (The exact exception message is as in the title). I don't understand where this error comes from. I have been dealing with this problem for a day and now I have got desperate about solving it. Is there a way to find the source of problem? Can you please help?</p> <p>Thanks in advance.</p> <p>Note: The weird thing is that it works when I create a new page without using the Master Page and migrate all the Facebook calls to the new page.</p>
