IP addresses
Sort IP addresses numerically
- Author: Dominique Fournier
Sorts a column containing IP addresses (IPv4 and IPv6) or IPv4 address and port delimited by ':' in typical dot notation / colon. This can be most useful when using DataTables for a networking application, and reporting information containing IP address.
Plug-in code
jQuery.extend( jQuery.fn.dataTableExt.oSort, {
"ip-address-pre": function ( a ) {
var i, item;
var m, n, t;
var x, xa;
if (!a) {
return 0
}
a = a.replace(/<[\s\S]*?>/g, "");
//IPv4:Port
t = a.split(":");
if (t.length == 2){
m = t[0].split(".");
}
else {
m = a.split(".");
}
n = a.split(":");
x = "";
xa = "";
if (m.length == 4) {
// IPV4
for(i = 0; i < m.length; i++) {
item = m[i];
if(item.length == 1) {
x += "00" + item;
}
else if(item.length == 2) {
x += "0" + item;
}
