Restructure Json

I now have a JSON response from the server like, but i want to restructure it, according to dates. for e.g i now have { 'items': [ { 'A': [

Solution 1:

I can only assume that you want this:

var arr = JSON.parse(response); // or something like that (assuming valid JSON)// or just assign the array literalvar result = {};
for (var i=0; i<arr.length; i++) {
    var date = arr[i].date,
        sales = arr[i].sales;
    if (date in result)
        result[date].push(sales);
    else
        result[date] = [sales];
}

Solution 2:

Assuming you get your JSON worked out:

<?php$list = array(
    array(
        'product'   => 'a',
        'date'      => '2012-08-01',
        'sales'     => 500,
    ),
    array(
        'product'   => 'b',
        'date'      => '2012-08-02',
        'sales'     => 600,
    ),
    array(
        'product'   => 'c',
        'date'      => '2012-08-01',
        'sales'     => 250,
    ),
    array(
        'product'   => 'd',
        'date'      => '2012-08-02',
        'sales'     => 800,
    ),
);

echo json_encode($list);
?><scriptsrc="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script><script>varJSON = '<?phpecho json_encode($list); ?>';
var pJson = jQuery.parseJSON(JSON);

var cArray = new Array();

for each ( i in pJson ) {
         if ( typeof cArray[i.date] == 'undefined' ) {
                cArray[i.date] = Array();
         }
        cArray[i.date].push(i.sales);
}
</script>

I added the php section to show what a JSON string should look like. This solution also requires jQuery.
