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 = 'bigbadwolf@grannysplace.com,hungry@hippos.com,youtalkin@to.me';

What (I think) it needs to be:

[
    {"email": "bigbadwolf@grannysplace.com"},
    {"email": "hungry@hippos.com"},
    {"email": "youtalkin@to.me"}
]

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 = 'bigbadwolf@grannysplace.com,hungry@hippos.com,youtalkin@to.me';
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 = 'bigbadwolf@grannysplace.com,hungry@hippos.com,youtalkin@to.me'; let emailList = to.split(',').map(values => { return { email: values.trim(), } }); console.log(emailList); 

Answer 3

Try changing the loop to this:

    var JSON = [];
    $(pieces).each(function(index) {
        JSON.push({'email': pieces[index]});   
    });

Answer 4

How about:

var to = 'bigbadwolf@grannysplace.com,hungry@hippos.com,youtalkin@to.me',
    obj = [],
    parts = to.split(",");

for (var i = 0; i < parts.length; i++) {
    obj.push({email:parts[i]});
}

//Logging
for (var i = 0; i < obj.length; i++) {
    console.log(obj[i]);
}

Output:

Object {email: "bigbadwolf@grannysplace.com"}
Object {email: "hungry@hippos.com"}
Object {email: "youtalkin@to.me"}
