实现代码：
(function($){
	$.fn.shuffleLetters = function(prop){
		// Handling default arguments
		var options = $.extend({
			// Default arguments
		},prop)
		return this.each(function(){
			// The main plugin code goes here
		});
	};
	// A helper function
	function randomChar(type){
		// Generate and return a random character
	}

})(jQuery);

function randomChar(type){
	var pool = "";

	if (type == "lowerLetter"){
		pool = "abcdefghijklmnopqrstuvwxyz0123456789";
	}
	else if (type == "upperLetter"){
		pool = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
	}
	else if (type == "symbol"){
		pool = ",.?/\\(^)![]{}*&^%$#'\"";
	}

	var arr = pool.split('');
	return arr[Math.floor(Math.random()*arr.length)];
}
