Jquery - JSON.stringify, array is empty

Question

i hope somebody can help me, the array value is empty in the post.

$(function start() {

    c_all = new Array('#div { font-color:#ff0000; border:1px solid #00ff00; }', '#div_2 { font-color:#ff0000; }', '.line2 { font-color:#00ffff; }');

    css(c_all);

});


function css(x) {

    values = new Array();

    for (i = 0; i < x.length; i++) {
        c0_selector = '' + x[i].match(/^.*{/) + '';
        c0_selector = c0_selector.replace(/\s*/g, '');
        c0_selector = c0_selector.replace(/{/, '');

        x[i] = x[i].replace(/^.*{/, '');
        x[i] = x[i].replace(/}/, '');

        c0_arr = x[i].split(';');

        values['' + c0_selector + ''] = new Array();

        $('#log').append(''+c0_selector+'<br />');

        for (i2 = 0; i2 < c0_arr.length; i2++)
        {
            values[''+c0_selector+''][i2] = c0_arr[i2].split(':');
            $('#log').append(''+c0_arr[i2]+'<br />');  
        }

    }

    $.ajax({
            type: 'post',
            data: JSON.stringify(values),
            contentType: 'application/json',
            dataType: 'json'
    });


}

Try making values an Object, (like it should be in javascript for named keys).

var values = {};

Also, it is a really good idea to declare your variables with the var keyword, so you're not creating global variables.

Also, no need for '' + c0_selector + '' since you already have a String. Just do c0_selector.

Finished product logs the populated Object. http://www.jsfiddle.net/V9Euk/450/

This is straight from the ECMAScript spec.

The abstract operation JA(value) serializes an array. It has access to the stack, indent, gap, and space of the invocation of the stringify method. The representation of arrays includes only the elements between zero and array.length – 1 inclusive. Named properties are excluded from the stringification. An array is stringified as an open left bracket, elements separated by comma, and a closing right bracket.

Basically any named properties are excluded from the result.
