Question

Ok, this question may be dumb, but I’m really stuck with this.

I want to a json structure like the following:

order: {
    currency: 'eur',
    order_items: [
        {
            id: 3,
            quantity: 1
        },
        {
            id: 67,
            quantity: 1
        }
    ]
}

What I’m doing right now is this:

function makeOrder(){
    var myArray = new Array();
    for(var i=0;i<bookedItemsArray.length;i++){
        var newObject = new OrderedItem(bookedItemsArray[i].id, bookedItemsArray[i].amount);
        myArray.push(newObject);
    }
    var mystring = JSON.stringify(myArray);
    //myString = "order: {currency: 'eur', order_items: " + myString + "}";
    console.log(myString);​
}

The way I get the data inside the order_items array is being cool, but when I try to concat the array with the rest (line in comments), I get:

?:??: W/?(?): Uncaught SyntaxError: Unexpected token ILLEGAL at file:///android_asset/www/november/js/t03/Booking/bookingProcess.js:96

Is there something I’m missing about the way a string and a JSON structure can be combined?

Thank you very much.

why don’t you do it like this?

var x = {
    order: {
        currency: 'eur',
        order_items: []
    }
};
for (var i = 0; i < 10; i++) {
    var newObject = {
        i: i,
        Text: 'Some Text'
    };
    x.order.order_items.push(newObject);
}

var str = JSON.stringify(x);

look at this fiddle: http://jsfiddle.net/9V6Vb/

Here is the generated JSON:

{
    "order": {
        "currency": "eur",
        "order_items": [{
            "i": 0,
            "Text": "Some Text"},
        {
            "i": 1,
            "Text": "Some Text"},
        {
            "i": 2,
            "Text": "Some Text"},
        {
            "i": 3,
            "Text": "Some Text"},
        {
            "i": 4,
            "Text": "Some Text"},
        {
            "i": 5,
            "Text": "Some Text"},
        {
            "i": 6,
            "Text": "Some Text"},
        {
            "i": 7,
            "Text": "Some Text"},
        {
            "i": 8,
            "Text": "Some Text"},
        {
            "i": 9,
            "Text": "Some Text"}]
    }
}​
