copied!<p>Yes, you can do it like this:</p> <pre><code>$('#someid').somePlugin('option', 'animation', 5000); </code></pre> <p>Additionally, you can change multiple options at once via:</p> <pre><code>$('#someid').somePlugin('option', {animation: 5000, otherOption: 'blah'}); </code></pre> <p>I should mention this only works for <em>certain</em> if you're using "official" jQuery plugins. A lot of plugin authors adhere to this design pattern, but not all do. Also, if you develop a plugin using the <a href="http://jqueryui.com/widget/" rel="nofollow">jQuery UI Widget Factory</a>, you get this functionality for free.</p> <hr> <p>EDIT: Since the OP is authoring his own plugin, we can show an example of how to facilitate this functionality with a custom plugin. Taken directly from the <a href="http://docs.jquery.com/Plugins/Authoring#Plugin_Methods" rel="nofollow">jQuery plugin authoring page</a>:</p> <pre><code>(function( $ ){ var methods = { init : function( options ) { //Extend options here with your //defaults and init your plugin }, option: function( key, value ){ options[key] = value; } }; $.fn.somePlugin = function( method ) { // Method calling logic if ( methods[method] ) { return methods[ method ].apply( this, Array.prototype.slice.call( arguments, 1 )); } else if ( typeof method === 'object' || ! method ) { return methods.init.apply( this, arguments ); } else { //some error that method doesnt exist } }; })( jQuery ); $('div').somePlugin({someOption: true}); //..later $('div').somePlugin('option', 'someOption', false); </code></pre>
