function FinalAmount() {
var FinalPrice = document.getElementById("FinalPrice");
let AllProductTotalPrice = 0;
for (let index = 0; index < OrderedProductList.length; ++index) {
alert;
var CurrentProductTotal = 0;
CurrentProductTotal = OrderedProductList[index].TotalPrice;
console.log(CurrentProductTotal);
AllProductTotalPrice += CurrentProductTotal;
console.log(AllProductTotalPrice);
}
FinalAllProductPrice = AllProductTotalPrice;
FinalPrice.innerText = "RM" + FinalAllProductPrice;
}
This is my javascript code. I would have a question about why the console.log(CurrentProductTotal) is already an integer but the above AllProductTotalPrice is a string value. Is there any way to let its sum as an integer and bring it to the below FinalAllProductPrice. Please help me TT
I think the easiest way would be to
use Number() to parse a string to a number. (we don't define integers specifically in javascript)
const num = "1234"
Number(num)
⚠️ If you give it a string which does not solely consist out of numbers it will return NaN
So in your example that would be:
CurrentProductTotal = OrderedProductList[index].TotalPrice
Now to your questions:
console.log() automatically displays it formatted for you. I would use the typeof operator to check whether CurrentProductTotal is really a number, or a string which the console formats differently which is a bit confusing.Try this in your browser console:
const num = "1234"
> undefined
num
> '1234'
console.log(num)
> 1234 // formatted like a number
console.log(num, typeof num)
> 1234 string // still formatted like a number, but a string in reality
