I'm trying to dynamically create a JS object which has an array inside such as this one:
//other values omitted for clarity
"items": [
{
"name": "T-Shirt",
"unit_amount": {
"currency_code": "USD",
"value": "90.00"
},
"quantity": "1",
"category": "PHYSICAL_GOODS"
},
{
"name": "Shoes",
"unit_amount": {
"currency_code": "USD",
"value": "45.00"
},
"quantity": "2",
"category": "PHYSICAL_GOODS"
}
],
I am able to create a single value with this code:
var product = {};
product.name = "T-Shirt";
product.quantity = "1";
product.category = "PHYSICAL_GOODS";
var subproduct = {};
subproduct.currency_code = "USD";
subproduct.value = "90.00";
product.unit_amount = subproduct;
var jsonString= JSON.stringify(product);
Which creates:
{
"name": "T-Shirt",
"unit_amount": {
"currency_code": "USD",
"value": "90.00"
},
"quantity": "1",
"category": "PHYSICAL_GOODS"
}
How can I add up the created values inside the array? I have an onclick event for providing the values for any given "item" in the example. For clarity, I do not know beforehand how many "items" the array will have.
You are on the right path, just iterate your code and put it in an array :
var productList = [];
for (var i = 0 ; i < 2; i++) {
// your code
var product = {};
product.name = "T-Shirt";
product.quantity = "1";
product.category = "PHYSICAL_GOODS";
var subproduct = {};
subproduct.currency_code = "USD";
subproduct.value = "90.00";
product.unit_amount = subproduct;
productList.push(product);
}
var answer = JSON.stringify(productList);
console.log(answer);To add the object to an array you should use the array method .push().
You could do it in the following way:
// Object which has a property `items`, where we will store product objects
var main = {
items: []
};
// Create the full product object
var product = {
name: "T-Shirt";
quantity: "1";
category: "PHYSICAL_GOODS";
unit_amount: {
currency_code = "USD";
value = "90.00";
}
};
// Push the new object to the `items` array
main.items.push(product);
