如何在Facebook上分享我的网站内容

Question

I have a website and on that I have a facebook button named as share. I want that when user clicks on that button the content of my webpage should share on his wall. My code is like this in my head tag of page:

<script>
    function fbs_click(){
        u = location.href;
        t = document.title;
        window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&t='+encodeURIComponent(t),'sharer','toolbar=0,status=0,width=626,height=436');
        return false;
    }
</script>

I also know that u= url of your content page t= title or site name and this is inside the body tag:

<a rel="nofollow" href="http://www.facebook.com/share.php?u=http://lums.edu.pk/event-detail/lecture-on-citation-management-and-referencing-1133"
class="fb_share_button" onclick="return fbs_click()" target="_blank"  
style="text-decoration:none;">Share</a>

?u is the link I want to share. This code open a share page for me, and share just my url not the content of my page. My content includes an image, tittle and detail (I'm fetching these values from database table). Please some one help me.

Have a look over OpenGraph tags like the ones below :

<meta property="og:title" content="TITLE" /> 
<meta property="og:image" content="URL" /> 
<meta property="og:description" content="DESCRIPTION" /> 
<meta property="og:url" content="URL" />

This example is using JSP. JS is based on top example.

<a id="fb_link" href="#fb_link" onclick="fbs_click('${product.id}');">Share me on FB</a>

function fbs_click(id) {
var url = 'http://www.facebook.com/sharer.php?u=' +
    encodeURIComponent('https://www.mysite.com.au/product/detail?advertiseId=') + id;
window.open(url, 'Share on FaceBook', 'left=20,top=20,width=550,height=400,toolbar=0,menubar=0,scrollbars=0,location=0,resizable=1');
return false;
}

Have to mention that for some magic reason location=0 doesn't work in my firefox ...
