There are various options you have how you can access the your JSON to display the values, which are to use bracket [] notation or add a new property to your JSON so you can use dot . notation.
Here are some simple ways of doing both. (To see the results of what is being output open your browser developer tools > console)
The first console.log() accesses the values using bracket notation.
The for loop adds a new key value pair into your JSON.
The second console.log() access the values using dot . notation to access the newly created value
var obj = [
{"@networkName":"nameOfNetwork1"},
{"@networkName":"nameOfNetwork2"}
];
console.log(obj[0]["@networkName"]);
// This will log "nameOfNetwork1"
for(var i = 0; i < obj.length; i++) {
// To will add a new key value into your data with a key name of newName
obj[i].networkName = obj[i]["@networkName"];
}
console.log(obj[0].networkName);
// This will log "nameOfNetwork1"
@. You could access it as is (myObject["@networkName"]) or replace it at some point (myObject.networkName = myObject["@networkName"])
