title: Getting Information From Html
body: <p>I have an e-commerce website. I want to give html code block to users, for only one product so they can paste this code block on their web sites. This code block contains  tag and an input element. When this button clicked, my web site opened in iframe and shows any specific product's informations.</p>
  
  <p>Here is my problem: How can I get product id? Should code block that I give to users, contains this information? </p>
  
  <p><strong>EDIT</strong>
  I am trying to do like facebook's share buttons. Facebook give that code block</p>
  
  <pre><code>&lt;a name="fb_share"&gt;&lt;/a&gt; 
     &lt;script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" 
        type="text/javascript"&gt;
    &lt;/script&gt;
  </code></pre>
  
  <p>Iframe opened with my javascript code that give to users script tag like above. I don't want to give any specific url like "www.mysite.com?productId=123". How should I add product id ?</p>
