Using two jQuery versions on the same page

Question

I am making my project in twitter bootstrap. I am using a file upload script extension with jQuery. This plugin is already developed. I just ave to place it.

But bootstrap is developed for some other jquery version and this plugin is developed with 1.5.1 version of jQuery.

I am planning to not to import the 1.5.1 version. Will it create an problem?

_I am planning to not to import the 1.5.1 version. Will it create an problem?_ We do not know what jQ features you have used in the plugin. Just replace the jQuery with the newest version and check if your plugin works or not. — strah, Mar 13 '13 at 10:55

If you want to include both the js files..you can use jquery js files of multiple versions by using noConflict ..there is no problem with this

 <!-- load jQuery1.5 -->
    <script type="text/javascript" src="jquery/jquery-1.5.js"></script>
    <script type="text/javascript">
    var jQuery_1_5 = $.noConflict(true);
    </script>

    <!-- load jQuery 1.9 -->
    <script type="text/javascript" src="jquery/jquery-1.9.js"></script>
    <script type="text/javascript">
    var jQuery_1_9= $.noConflict(true);
    </script>

Remember that you can't use the "dot" in a variable name. – MarcoK Mar 13 '13 at 10:44

If you want to use JQuery 1.9, there is a JQuery Migrate plugin which might be useful.

It is designed for when you are migrating to a newer JQuery version. I have used it in the past, it adds the old features again and will give you a warning if you ever make use of a function which is depreciated.

This way you will know if the file upload plugin makes use of depreciated code and could possibly update it.
