The utilization of count variable is not permitted in embedded array lookup

I've been using C# for quite some time, but I'm facing a challenge with a basic concept in the JavaScript part of my project. The following code snippet is part of a larger function I've written:

addPaymentsToBreakdown = function () {
    for (var count = 0; count < checkedPayments.length; count++) {
        (function (count) {
            console.log(checkedPayments[0][count].value); 
        })(count); 
    }
}

This code snippet uses an array 'checkedPayments' that is properly instantiated elsewhere. However, I'm struggling to understand why I can't simply use the 'count' variable to iterate over the second tier of indexes in the array. I can access individual indexes manually or print the entire array using console.log(), but when I try to combine the 'count' variable with the array index, I encounter issues. The error message I'm receiving is

Uncaught TypeError: Cannot read property 'value' of undefined.
Can someone help me understand why this isn't working and provide a solution? Thank you.

Answer №1

Thank you to everyone for your valuable feedback. I was able to uncover the solution and I am excited to share it with you all. Here is the code snippet that helped me achieve this:

addPaymentsToBreakdown = function () {
        console.log('checkedPayments:', checkedPayments); 
        for (var count = 0; count < checkedPayments.length; count++) {
            console.log(checkedPayments[count][0].value);
        }
    }

I successfully implemented the solution I was looking for by delving deeper into the [count][0].value. This allowed me to access the necessary layer within the array and retrieve the values of the three elements, which correspond to the ID's from the database. With this information, I can now proceed with my query as needed. I greatly appreciate all the assistance provided ;)
