Obtain or Check Which jQuery Version

16 May 2012 - JavaScript, jQuery, Quick Tip - James Brown - Comments Off on Obtain or Check Which jQuery Version

If you need to check which version of jQuery you are running (think Firebug or possibly), you can check the version using the following:

jQuery.fn.jquery

or use the shortcut

$.fn.jquery

Also, if you are loading multiple versions of jQuery on your page and need to verify, you can also use the property:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>

<script language='JavaScript'>
  var $_144 = jQuery.noConflict(true);
</script>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

<script language='JavaScript'>
 var $_171 = jQuery.noConflict(true);
  
  console.log($_144.fn.jquery);   //   "1.4.4"
  console.log($_171.fn.jquery);   //   "1.7.1"
</script>
