Loop on array of objects

by gioking posted Mar 12 2018, 7:00

Hi, I have a question, I'm building a bot that have to call a rest service made by me, the service response is a List of json objects but at the moment I can get only the first element of the array eg. array[0].Name ecc...

My ask is: how can I loop the array to have the following formatted data ?

Name: Pluto

Surname: Paperino

ecc...

this is my method:

function getpersons() {
debug(star);
var result = Http.requestJSON("http://endospore.xxxx.com:85/api/Data/GetPersons");

//var person = result[0].Name + " " + result[0].Surname;

var text = "Persons are: ";
for (i = 0; i < result.length; i++) {
text = text + person[i] + "<br>";
}
return text;
}

Thanks

There are a few ways to iterate over an array.
In your code use result.length() not result.length

var result = Http.requestJSON("http://endospore.xxxx.com:85/api/Data/GetPersons"); var text = "Persons are: "; for (i = 0; i < result.length(); i++) { var person = result[i].Name + " " + result[i].Surname; text = text + person + "<br>"; }

You can also use,

var result = Http.requestJSON("http://endospore.xxxx.com:85/api/Data/GetPersons"); var text = "Persons are: "; for (person in result) { text = text + person.Name + " " + person.Surname + "<br>"; }

Or to iterate over an array's elements, or any attribute set of an object use,

var result = Http.requestJSON("http://endospore.xxxx.com:85/api/Data/GetPersons"); var text = "Persons are: "; for (person in result.element) { text = text + person.Name + " " + person.Surname + "<br>"; }
