RequireJS - jQuery plugins with multiple jQuery versions

问题

I am trying to wrap some legacy js code in modules so that they can be loaded with RequireJS.

I have three jQuery plugins, let's call them a,b and c.

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

So anytime the plugin a is required, the jQuery that needs to be loaded is version 1.4.2. My require.config looks something like:

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

And the 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 scenario so that if any plugin needs a certain version of jQuery, and the others don't require a version, that and only that certain version is loaded?

Thanks in advance.

If you are really using jquery 1.4 this version doesn't support Requirejs, you should define de shim configuration, however you will have a conflict as jquery defines $ object globally, so it will overwrite any existing global $ variable. I think you can avoid this problem using jQuery.noConflict.
