Facebook的問題，如按鈕，XFBML，動態網址？

所以我一直無法讓我的Facebook像按鈕一樣工作。我試圖將它們放在很多頁面上，而無需每次都在代碼段的'href'字段中輸入url。我試過用js來動態改變href參數，但是當我點擊'like'按鈕時，它不會經過 - 又名不會發布到我的臉書。下面是代碼：Facebook的問題，如按鈕，XFBML，動態網址？

<script> 
    window.fbAsyncInit = function() { 
    // init the FB JS SDK 
    FB.init({ 
     appId  : '456678891040542', // App ID from the App Dashboard 
     channelUrl : '//WWW.UNICONUTRITION.COM/channel.html', // Channel File for x-domain communication 
     status  : true, // check the login status upon init? 
     cookie  : true, // set sessions cookies to allow your server to access the session? 
     xfbml  : true // parse XFBML tags on this page? 
    }); 

    // Additional initialization code such as adding Event Listeners goes here 

    }; 

    // Load the SDK's source Asynchronously 
    (function(d){ 
    var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; 
    if (d.getElementById(id)) {return;} 
    js = d.createElement('script'); js.id = id; js.async = true; 
    js.src = "//connect.facebook.net/en_US/all.js"; 
    ref.parentNode.insertBefore(js, ref); 
    }(document)); 
</script> 


    <li class="sloo"><fb:like id="fb" href="www.asdf.com" layout="box_count"></fb:like> 

    </li> 

    <script type="text/javascript"> 
var sUrl = window.location; 
document.getElementById('fb').setAttribute('href', sUrl); 
</script>
