Javascript or Ruby. Reformat a JSON object

Question

I need to turn this JSON object:

[
    [
        "[email protected]"
    ],
    [
        "[email protected]"
    ],
    [
        "[email protected]"
    ],
    [
        "[email protected]"
    ]
]

Into this:

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

How is this done?

Well, that's really just an array of arrays, but that's besides the point. Just loop through the array of arrays and push the relevant data onto the new array in your object:

var my_new_object = {};
my_new_object['data'] = [];

for (var i = 0; i < your_array.length; i++) {
  my_new_object.data.push({"email": your_array[i][0]});
}

Working demo.

You're close, but I think you need: your_array[i][0]

Its very close. The [] around the email address should not be there. How can I remove it? pastie.org/1812997.

Javascript:

var original = [
[
    "[email protected]"
],
[
    "[email protected]"
],
[
    "[email protected]"
],
[
    "[email protected]"
]
];

var output = {};
output.data = new Array();
for(var i=0;i<original.length;i++){
    var o = new Object();
    o.email = original[i][0];
    output.data.push(o);
}

you can test it here: http://jsfiddle.net/v3fnk/

var data=[["[email protected]"],["[email protected]"],["[email protected]"],["[email protected]"]];

for (var i in data) {
    for (var x in data[i]) {
        $("#info").append(data[i][x] + '<br/>');
    }

}
