title: Get Boostrap modal position with jQuery
body: <p>In my code, if you click the button inside the modal I'm trying to get it to alert the left/top position of the modal, however it always returns as 0.</p>
  
  <p>I'm not sure why the browser can't return these values.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$(window).on('load',function(){
    $('#myModal').modal('show');
  });
  
  function getPos() {
    alert("Top: "+ $("#myModal").position().top + " Left: " +$("#myModal").position().left);
  }</code></pre>
