我正在为一个项目开发插件,以下代码是我基于《Smashing Magazine》上的一篇文章中的“A Lightweight Start”部分编写的: http://coding.smashingmagazine.com/2011/10/11/essential-jquery-plugin-patterns/。目前它已经完全符合我的需求,但是该文章的其余部分离题了并讨论了jQuery UI小部件,我认为我需要使用jQuery UI库,但我不想使用。请注意,html标签应保留。

// the semi-colon before the function invocation is a safety
// net against concatenated scripts and/or other plugins
// that are not closed properly.
;(function ( $, window, document, undefined ) {
// undefined is used here as the undefined global
// variable in ECMAScript 3 and is mutable (i.e. it can
// be changed by someone else). undefined isn't really
// being passed in so we can ensure that its value is
// truly undefined. In ES5, undefined can no longer be
// modified.
// window and document are passed through as local
// variables rather than as globals, because this (slightly)
// quickens the resolution process and can be more
// efficiently minified (especially when both are
// regularly referenced in your plugin).
// Create the defaults once
var pluginName = 'defaultPluginName',
defaults = {
propertyName: "value"
};
// The actual plugin constructor
function Plugin( element, options ) {
this.element = element;
// jQuery has an extend method that merges the
// contents of two or more objects, storing the
// result in the first object. The first object
// is generally empty because we don't want to alter
// the default options for future instances of the plugin
this.options = $.extend( {}, defaults, options) ;
this._defaults = defaults;
this._name = pluginName;
this.init();
}
Plugin.prototype.init = function () {
// Place initialization logic here
// You already have access to the DOM element and
// the options via the instance, e.g. this.element
// and this.options
};
// A really lightweight plugin wrapper around the constructor,
// preventing against multiple instantiations
$.fn[pluginName] = function ( options ) {
return this.each(function () {
if (!$.data(this, 'plugin_' + pluginName)) {
$.data(this, 'plugin_' + pluginName,
new Plugin( this, options ));
}
});
}
})( jQuery, window, document );
我现在需要给这个插件添加一个方法,但是我不太清楚该如何操作。
该方法需要以这样的方式工作:通过控制台调用方法并传递一个值,就能动态地改变插件在页面上创建实例的属性(最终这将通过其他过程来完成,但目前使用控制台)。
我应该如何修改上面的代码以实现这一点呢?还是我的方向错了呢?
非常感谢任何帮助,复杂的JavaScript有时会让我感到困惑,但我喜欢尝试以“最佳实践”来完成任务。
