1. ip正则表达式验证

java:

private boolean IsIpAddressValidOrEmpty(String ip) {
　　if (ip == null) return false;
　　String temp = "^(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])\\.(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])\\.(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])\\.(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])$";
　　return ip.matches(temp);
}

js:
var temp = /^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$/
if (!temp.test(detailIP)) {
mx.indicate("warn", "IP格式错误,请重新输入!");
return;
}

js:

以http://或https://开头的URL验证：   /(http|https):\/\/([\w.]+\/?)\S*/;

IP地址正则：  /^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])(\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])){3}$/;

 

IP地址+端口正则： /^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])(\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])){3}:([0-9]|[1-9]\d{1,3}|[1-5]\d{4}|6[0-5]{2}[0-3][0-5])$/;

http://192.168.1.1:8080或 https://192.168.1.1:8080 正则：/^(http|https):\/\/(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])(\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])){3}:([0-9]|[1-9]\d{1,3}|[1-5]\d{4}|6[0-5]{2}[0-3][0-5])$/;
