Many a times you would require validation for IP Address if there is a field on the form.
- A valid IPv4 address should be in the form of xxx.xxx.xxx.xxx, where xxx is a number from 0-255.
- Class A IP addresses are networks belonging from 1.0.0.0 to 127.0.0.0. Class B is networks 128.0.0.0 through 191.255.0.0. Class C is 192.0.0.0 through 223.255.255.0
- IP Address 0.0.0.0 is valid since it contains four octets, each within the range 0 through 255 inclusive. However, it's not usable as a real IP address.
- Valid IP Address always are in between the extreme values, "0.0.0.0" and "255.255.255.255" excluding these extreme values.
For example below are few valid IPv4 Addresses:
10.10.10.10
192.168.1.1
Invalid IPv4 Addresses:
192.168.1.256
255.245.276.243
There exists already a field type IP Address; you can try using that.
Here is the onChange Script on the field:
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var val = validateIP(newValue);
if(val == 'reserved'){
alert('This is a reserved IP address so cannot be used');
g_form.clearValue('fieldName');
}
else if(!val){
alert('Please enter valid IP Address');
g_form.clearValue('fieldName');
}
}
function validateIP(ip) {
alert('inside function');
if(ip == '0.0.0.0' || ip == '255.255.255.255')
return 'reserved';
//Check Format
var ip = ip.split(".");
if (ip.length != 4) {
return false;
}
//Check Numbers
for (var c = 0; c < 4; c++) {
//Perform Test
if ( ip[c] <= -1 || ip[c] > 255 ||
isNaN(parseFloat(ip[c])) ||
!isFinite(ip[c]) ||
ip[c].indexOf(" ") !== -1 ) {
return false;
}
}
return true;
}
