location.href和location.search区别

location.href和location.search区别：

location.href返回完整的 URL，如：var url = location.href;  //url=http://write.blog.youkuaiyun.com/postedit?ref=toolbar&ticket=ST-238906-YIVrWAhpAUsswkCIvYkb-passport.youkuaiyun.com

location.search:是从当前URL的?号开始的字符串,如 var searchstring = location.search; //同上面的链接，

                        searchstring 为"?ref=toolbar&ticket=ST-238906-YIVrWAhpAUsswkCIvYkb-passport.youkuaiyun.com"

如果要获取参数ref：

 var arr = params.substring(1).split("&"); 

 var ref=arr[0];
