How to multiple version of jQuery?

Yes. You can use multiple versions of jQuery on the same page. To avoid any kind of conflict, use the jQuery.noConflict() method.
<script>var $jq = jQuery.noConflict(true);</script> <script> $(document).ready(function(){ $("button").click(function(){ alert($().jquery); alert($jq().jquery); }); }); </script>
While executing code, $.noConflict() method to give control of the $ variable back to whichever library first implemented it.

jQuery.noConflict() method

jQuery.noConflict() method allows you to use multiple frameworks , while using jQuery. The noConflict() method releases the hold on the $ shortcut identifier, so that other scripts can use it. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. In case of multiple versions of jQuery are loaded (which is not recommended), calling $.noConflict(true) from the second version will return the globally scoped jQuery variables to those of the first version.
