RequireJS - jQuery plugins with multiple jQuery versions

Question

I am trying to port some obsolete js codes to modules so that they can be loaded using RequireJS.

I have three jQuery plugins, let them be called a, b and c.

• Plugin a works with any version of jQuery
• Plugin b works with jQuery version 1.4.2
• The c plugin uses a and b and works with any version of jQuery.

Therefore, at any time when plugin a is required, the downloadable jQuery is version 1.4.2. My require.config looks something like this:

require.config({ paths:{ "jquery": "libs/jquery.1.9.1.min", "jquery1-4-2" : "libs/jquery1.4.2.min" }); 

And plugins are defined as follows:

 plugin a: define(["jquery"], function($){ (...) }); plugin b: define(["jquery1-4-2"], function($){ (...) }); plugin c: define(["jquery", "a","b"], function($){ (...) }); 

How can I configure this script so that if some plug-in needs a specific version of jQuery, while others do not require a version, then only this specific version is loaded?

Thanks in advance.

If you are really using jquery 1.4, this version does not support Requirejs, you have to define the shim configuration, but you will have a conflict because jquery defines $ object globally, so it will overwrite any existing global $ variable. I think you can avoid this problem by using jQuery.noConflict.
