[Amit Kumar6]

Hi,

I have requirement for validating the IP Address in Catalog item in the format (0-235).(0-235).(0-235).(0-235)

Kindly suggest me how can i achieve this.

Thanks

Try any of the below options:

1. var ipaddress = current.ip_address;
2. function ValidateIPaddress(ipaddress)    
3. {  
4. if (/^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/.test(ipaddress))  
5.   {  
6.       return (true) //allow access  
8.   }  
9. alert("You have entered an invalid IP address!")  
10. return (false) //deny access
11. }

OR

1. var ipAddress = current.ip_address;
2. var ipAdressV4 = new SncIPAddressV4(ipAddress);  
3. var startIP = new SncIPAddressV4(IP Address Start);  
4. var endIP = new SncIPAddressV4e(IP Address End);  
5. var range = new SncIPRangeV4(startIP, endIP);  
6. if (range.contains(ipAdressV4))    
7. //allow access  
8. else  
9. //deny access  
10. }

apparently, this no longer works:

Background message, type:error, message: Illegal access to constructor com.snc.commons.networks.IPRangeV4(com.snc.commons.networks.IPAddressV4,com.snc.commons.networks.IPAddressV4)
