运行事件回调的同时禁用当前元素，避免相同的回调再次被触发，在回调中可以调用 enable 函数解除禁用。

jquery.ice.js

;(function($, undefined){
/**
 * @param  {String}   types       event types
 * @param  {String}   [selector]  
 * @param  {Function} fn          function(e, enable){}
 * @param  {Object}   [option]
 * @return {Object}               jQuery Object
 * @version 0.3
 */
$.fn.ice = function(types, selector, fn, option){
  if (typeof selector == 'function' ){
		option = fn;
		fn = selector;
		selector = undefined;
	};

	option = $.extend({
		onDisable: function(){},
		onEnable: function(){}
	}, option);

	this.on(types, selector, function(e) {
		var that = this,
			$that = $(that);

		if ($that.is('.disabled')) return false;

		$(this).addClass('disabled');
		option.onDisable.call(that, e);

		return fn.call(that, e, function(){
			$that.removeClass('disabled');
			option.onEnable.call(that, e);
		});
	});
	return this;
}
})(jQuery);
