What is the best way to retrieve the index of an object within an array?

https://i.sstatic.net/We8lJ.pngHow can I retrieve the index of an object's array? https://i.sstatic.net/hmDKx.png

I am looking to access the index of the items array within the form object.

https://i.sstatic.net/OxePH.png

When adding a new item row, the unit_price of the new row overrides previously created rows.

The issue stems from this scenario

 productSelected(product) {
     this.form.items['id'] = product.id;
     this.form.items['unit_price'] = product.price;
   }

I aim to set the product price to form.items[index].unit_price

Answer №1

It seems like your question is a bit unclear, but based on my interpretation, I will provide two types of answers:

1) Retrieve all the values from the items array

form.items.map((item)=> console.log(item));

2) Retrieve a specific index value:

const findIndex = 0;
form.items[findIndex];

Answer №2

It seems like you are looking to retrieve the index of an item from an array. Here is a solution that might assist you:

myArray.forEach((element, idx) => {
 console.log('element:', element)
 console.log('index:', idx) // index of the element
})
