//兼容的事件绑定方法
var addEvent = function( obj, type, fn ) {
	if (obj.addEventListener)
		obj.addEventListener( type, fn, false );
	else if (obj.attachEvent){
		obj["e"+type+fn] = fn;

//生成用户唯一标示
var getUid = function(){
	var o = new Date().getUTCMilliseconds();
    var suid = (Math.round(Math.random() * 2147483647) * o) % 10000000000;

//关于cookie的请求

//cookie调用方法

	var suid = cookie.get("suidkey");

		suid = getUid();
		cookie.add("suidkey",suid,24);
		countUrl+=suid+"|1";
	}else{

	}
//给标签一个data-rel之类的属性，为该类属性的标签绑定事件

$(document).ready(function(){
    $("a[data-rel^='prettyPhoto']").prettyPhoto();
  });
