title: Changing Facebook meta tag Content Attribute using JQuery
body: <p>I want to know how can I use JQuery in order to replace the content attribute of my Facebook meta tags.</p>
  
  <p>I searched StackOverflow and what I've found was this example:</p>
  
  <pre><code>$("meta[property=og:title]").attr("content", title);
  $("meta[property=og:url]").attr("content", url);
  </code></pre>
  
  <p>In my code I have the following meta tags:</p>
  
  <pre><code>&lt;meta property="og:title" content="some content"/&gt;
  &lt;meta property="og:url" content="some content"/&gt;
  &lt;meta property="og:site_name" content="some content"/&gt;
  </code></pre>
  
  <p>When I run the function that should change the content for the 'title' and 'url' variables, the change doesn't take place. The same values for the 'content' still remains the same.</p>
  
  <p>I want to know how, if it's possible, to use JQuery to change the value of Facebook's meta tags.</p>
