How to save new array?

Question

I am have an array:

var data = [
    [0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0]
];

And if I run my code this array changes to something like:

var data = [
    [1, 0, 0, 0, 0],
    [1, 1, 0, 0, 0],
    [1, 1, 1, 0, 0]
];

And my question: How to save or copy this new array?

That's not very specific. Save it *where*? localStorage? Make an AJAX call? — vcsjones, Sep 11 '11 at 15:16

There was very detailed dicussion about related topic. You can found here details: How do you clone an Array of Objects in Javascript?

And probably the most clear answer you can found here What is the most efficient way to deep clone an object in JavaScript? from John Resig

About saving issue - more details needed where exactly you want to save it.

Print data to <textarea>

script

var data = [
                [1, 0, 0, 0, 0],
                [1, 1, 0, 0, 0],
                [1, 1, 1, 0, 0]
            ];

$(document).ready(function () {
    var printData = '';
    $.each(data, function (index, value) {
        printData += '[';
        $.each(value, function (index, value) {
            printData += value + ','
        });
        printData += ']\r\n';
    });

    $('#console').val(printData);
});

html

<textarea id="console"></textarea>

Also not to mention that above code uses jquery and not plain javascript. – Achshar Sep 11 '11 at 15:50
Why not just use `JSON.stringify`? – vcsjones Sep 11 '11 at 15:51
Yes, it can be used, but in this case the presentation will be not so clear (without line breaks) – Samich Sep 11 '11 at 16:12
