Using jQuery with Other Libraries

Updates!!:

What can we do to fix this?

You can try moving the jQuery.js to top and than use jQuery.noConflict().

If that is not an option you can do the following –

IMPORTANT – Do not use [REPLACE ALL]

  • Edit prototype.js – find where it defines function $() and change the name to function $$$()
  • Still in prototype.js, carefully replace each occurrence of $(…) with $$$(…), but don’t touch anything which says $$(…)
  • Edit each of the other *.js files (e.g. effects.js) and carefully replace each occurrence of $(…) with $$$(…), but don’t touch anything which says $$(…).
  • That is it.

And just in case you have trouble doing the above, Following links point to already edited prototype.js and effects.js. Please remember all the references to these files must start with $$$ instead of $.

Download – Prototype.js

Download – Effects.js

GENERAL

The jQuery library, and virtually all of its plugins are constrained within the jQuery namespace. As a general rule, “global” objects are stored inside the jQuery namespace as well, so you shouldn’t get a clash between jQuery and any other library (like Prototype, MooTools, or YUI).

That said, there is one caveat: By default, jQuery uses “$” as a shortcut for “jQuery”

OVERRIDING THE $-FUNCTION

However, you can override that default by calling jQuery.noConflict() at any point after jQuery and the other library have both loaded. For example:

 <html>
 <head>
   <script src="prototype.js"></script>
   <script src="jquery.js"></script>
   <script>
     jQuery.noConflict();

     // Use jQuery via jQuery(...)
     jQuery(document).ready(function(){
       jQuery("div").hide();
     });

     // Use Prototype with $(...), etc.
     $('someid').hide();
   </script>
 </head>
 <body></body>
 </html>

This will revert $ back to its original library. You’ll still be able to use “jQuery” in the rest of your application.

Additionally, there’s another option. If you want to make sure that jQuery won’t conflict with another library – but you want the benefit of a short name, you could do something like this:

 <html>
 <head>
   <script src="prototype.js"></script>
   <script src="jquery.js"></script>
   <script>
     var $j = jQuery.noConflict();

     // Use jQuery via $j(...)
     $j(document).ready(function(){
       $j("div").hide();
     });

     // Use Prototype with $(...), etc.
     $('someid').hide();
   </script>
 </head>
 <body></body>
 </html>

You can define your own alternate names (e.g. jq, $J, awesomeQuery – anything you want).

Finally, if you don’t want to define another alternative to the jQuery name (you really like to use $ and don’t care about using another library’s $ method), then there’s still another solution for you. This is most frequently used in the case where you still want the benefits of really short jQuery code, but don’t want to cause conflicts with other libraries.

 <html>
 <head>
   <script src="prototype.js"></script>
   <script src="jquery.js"></script>
   <script>
     jQuery.noConflict();

     // Put all your code in your document ready area
     jQuery(document).ready(function($){
       // Do jQuery stuff using $
       $("div").hide();
     });

     // Use Prototype with $(...), etc.
     $('someid').hide();
   </script>
 </head>
 <body></body>
 </html>

This is probably the ideal solution for most of your code, considering that there’ll be less code that you’ll have to change, in order to achieve complete compatibility.

INCLUDING JQUERY BEFORE OTHER LIBRARIES

If you include jQuery before other libraries, you may use “jQuery” when you do some work with jQuery, and the “$” is also the shortcut for the other library. There is no need for overriding the $-function by calling “jQuery.noConflict()”.

 <html>
 <head>
   <script src="jquery.js"></script>
   <script src="prototype.js"></script>
   <script>
     // Use jQuery via jQuery(...)
     jQuery(document).ready(function(){
       jQuery("div").hide();
     });

     // Use Prototype with $(...), etc.
     $('someid').hide();
   </script>
 </head>
 <body></body>
 </html>

REFERENCING MAGIC – SHORTCUTS FOR JQUERY

If you don’t like typing the full “jQuery” all the time, there are some alternative shortcuts:

  • Reassign jQuery to another shortcut
    • var $j = jQuery;
    • (This might be the best approach if you wish to use different libraries)
  • Use the following technique, which allows you to use $ inside of a block of code without permanently overwriting $:
    • (function($) { /* some code that uses $ */ })(jQuery)
    • Note: If you use this technique, you will not be able to use Prototype methods inside this capsuled function that expect $ to be Prototype’s $, so you’re making a choice to use only jQuery in that block.
  • Use the argument to the jQuery(document).ready(function($) {})
DOM ready event:
    • jQuery(function($) { /* some code that uses $ */ });
    • Note: Again, inside that block you can’t use Prototype methods.
