###url链接验证
var strRegex = "^((https|http|ftp|rtsp|mms)?://)"
+ "?(([0-9a-z_!~'().&=+$%-]+: )?[0-9a-z_!~'().&=+$%-]+@)?" //ftp的user@
+ "(([0-9]{1,3}.){3}[0-9]{1,3}" // IP形式的URL- 199.194.52.184
+ "|" // 允许IP和DOMAIN（域名）
+ "([0-9a-z_!~'()-]+.)" // 域名- www.
+ "([0-9a-z][0-9a-z-]{0,61})?[0-9a-z]." // 二级域名
+ "[a-z]{2,6})" // first level domain- .com or .museum
+ "(:[0-9]{1,4})?" // 端口- :80
+ "((/?)|" // a slash isn't required if there is no file name
+ "(/[0-9a-z_!~*'().;?:@&=+$,%#-]+)+/?)$";
var re = new RegExp(strRegex);
