Declare array of objects

Jeyasingh Yovan

I need to store array of objects and then convert that into string using JSON.stringify and transfer that string to external link. Below is my typescript code..

let orderItems: any[] = [];

let order_data = {};

this.storage.get("cart").then((cart) => {

cart.forEach((element, index) => {

orderItems.push({ "product_id": element.product.id, "quantity": element.qty });

});

console.log(orderItems);

order_data = {

"customer_name": "Singh",

"line_items": orderItems,

}

console.log(JSON.stringify(order_data));

In my console I got empty array of objects..... {"customer_name":"Singh","line_items":[]}

Anyone here pls help me out of this... Thank you in advance....

Hi Yovan,

codes looks fine it might be scoping issue just change let to var then try

var orderItems: any[] = [];
var order_data = {};

this.storage.get("cart").then((cart) => {
cart.forEach((element, index) => {
orderItems.push({ "product_id": element.product.id, "quantity": element.qty });
});
});
console.log(orderItems);
order_data = {
"customer_name": "Singh",
"line_items": orderItems,
}
console.log(JSON.stringify(order_data));

It is because you are pushing the same value again and again from orderitems.push().

Take a help from this will help you,
// Users
var users = {
user : {username: user9110252username, genrePref: user9110252genre},
jon : {username: 'Jon', genrePref: 'rock'},
lucy : {username: 'Lucy', genrePref: 'pop'},
mike : {username: 'Mike', genrePref: 'rock'},
luke : {username: 'Luke', genrePref: 'house'},
james : {username: 'James', genrePref: 'house'},
dave : {username: 'Dave', genrePref: 'bass'},
sarah : {username: 'Sarah', genrePref: 'country'},
natalie : {username: 'Natalie', genrePref: 'bass'}
}
// Users array
var allUsers = [];
//add values to array
allUsers.push(allUsers, user, jon, lucy, mike, luke, james, dave, sarah, natalie);
// Populate users array
for(var key in users)
{
allUsers.push(users[key]);
}
