If you include 2 version of jQuery in a page how do you restrict a plugin to just one of them?

Question

So this question isn\'t as crazy as it might sound at first. I\'m developing a piece of javascript code to drop into my client\'s pages. What I\'m worried about is if they

Answer 1

You could use

(function($) {        

})(dom);

To wrap you calls.

This maps dom to $ for just the code within replacing any external $ definition.

But I am not sure if this works with 2 different jQuery, maybe jQuery cannot coexist with other jQuery versions.

Answer 2

There is a trick you could use. If your version of jQuery is second which loads, you will need first move to safety theirs version before you load it, something like this

<script type="text/javascript">
    (function($){
       var theirs_jquery = $;
    })(jQuery);
</script>

Then add your jQuery version script include tag

<script src="link/to/my/jquery.js"></script>
 <!-- add your plugins -->
<script src="link/to/my/jquery/plugins/plugin1.js"></script>
<script src="link/to/my/jquery/plugins/plugin2.js"></script>

then add another script block with folowing

<script type="text/javascript">
(function(){
    var $$ = jQuery; // this is your shortcut
    var $ = theirs_jquery; // put back their version
})(jQuery);
</script>

after this you can access your jquery version with $$ shortcut
