Programmatically: How to implement custom Magento jQuery plugins

Step 1: Create a new directory and file structure

Create a new directory YourCompany_YourModule under app/code/local and inside it create a new directory view and a file js under it. Inside the js directory, create a new file yourplugin.js. yourplugin.js

	// yourplugin.js
	(function($) {
    $.fn.yourPlugin = function() {
        // Your plugin code here
        return this;
    };
	})(jQuery);
	

Step 2: Add the JavaScript file to Magento's concatenation process

In your module's config.xml file, add the following code:

	
    
        
        
         
         yourcompany_yourmodule/js/yourplugin.js

Step 4: Use the custom plugin in your PHTML file
