title: jQuery selector not working on Windows Phone 7
body: <p>I have a strange problem with a web app for WP7 (7.1).</p>
  
  <p>The code that works with Chrome, Safari, etc.:</p>
  
  <pre><code>$.each(val, function(sub_key, sub_val) {
  
                  $("."+sub_key).html(sub_val);                       
  
  });
  </code></pre>
  
  <p>Examples for the variables in use:</p>
  
  <pre><code>sub_key : title-home
  sub_val : This is home
  </code></pre>
  
  <p>This does not work on WP7 (v. 7.1). I tried endless combinations but the only way to get the selector working is to define a static string inside the selector. Like so:</p>
  
  <pre><code>$.each(val, function(sub_key, sub_val) {
  
                  $(".title-home").html(sub_val);                     
  
  });
  </code></pre>
  
  <p>This is of course not an option.
  Is there some kind of bug in IE when joining strings like I did? </p>
  
  <p>BTW I think WP7 is using the IE 7 engine.</p>
  
  <p>Cheers Johe</p>
