jQuery: Convert string with comma separated values to specific JSON format

Question

I've been losing hours over something that might be trivial:

I've got a list of comma-separated e-mail addresses that I want to convert to a specific JSON format, for use with the Mandrill API (https://mandrillapp.com/api/docs/messages.JSON.html)

My string:

var to = '[email protected],[email protected],[email protected]';

What (I think) it needs to be:

[
    {"email": "[email protected]"},
    {"email": "[email protected]"},
    {"email": "[email protected]"}
]

I've got a JSFiddle in which I almost have it I think: http://jsfiddle.net/5j8Z7/1/

I've been looking into several jQuery plugins, amongst which: http://code.google.com/p/jquery-json But I keep getting syntax errors.

Another post on SO suggested doing it by hand: JavaScript associative array to JSON

This might be a trivial question, but the Codecadamy documentation of the Mandrill API has been down for some time and there are no decent examples available.

Answer 1

var json = [];
var to = '[email protected],[email protected],[email protected]';
var toSplit = to.split(",");
for (var i = 0; i < toSplit.length; i++) {
    json.push({"email":toSplit[i]});
}

Answer 2

Try this ES6 Version which has better perform code snippet.

'use strict';

let to = '[email protected],[email protected],[email protected]';

let emailList = to.split(',').map(values => {
    return {
        email: values.trim(),
    }
});

console.log(emailList);
