how to extract fields from an array, and then add new fields to get the data as follows:
var data = [
{"id":"1","name":"","data":"25u6s8f545d3"},
{"id":"2","name":"","data":"cd58de9d3c5d"},
];
the format of the data I want to get is as follows:
var data = [
{"id":"1","name":"","data":"25u6s8f545d3","mac":"25:u6:s8:f5:45:d3"},
{"id":"2","name":"","data":"cd58de9d3c5d","mac":"cd:58:de:9d:3c:5d"},
];
my current method is as follows:
for (var i = 0; i < data.length; iPP) {
var mac = data[i].data.toUpperCase();
mac1 = mac.substring(0, 2);
mac2 = mac.substring(2, 4);
mac3 = mac.substring(4, 6);
mac4 = mac.substring(6, 8);
mac5 = mac.substring(8, 10);
mac6 = mac.substring(10, 12);
var mac = mac1 + ":" + mac2 + ":" + mac3 + ":" + mac4 + ":" + mac5 + ":" + mac6;
data[i].mac = mac;
};
is there a better way? I think my method is a little bad.
