loop through records with letters as variable

Marius Vasile

I can loop through records with

$("#btnVerTest").on("click", function () {

    for (let i = 1; i <= 3; i++) {

        if ($("#txtCor" + i).text() == "DA") {
            $("#inputRasCor").val($("#txtRas" + i).text());
            $("#inputCor").val($("#txtCor" + i).text());
        }
    };
})

where txtCor has id from 1 to 3.

How can I loop through records if all id's have letters instead of numbers, A, B and C? txtCorA, txtCorB, txtCorC and so on

Accepted answer

If your IDs have letters instead of numbers (e.g., txtCorA, txtCorB, txtCorC), you can use an array of letters to loop through them.

$("#btnVerTest").on("click", function () {
    const letters = ['A', 'B', 'C']; // Add more letters if needed

    for (const letter of letters) {
        const txtCorId = "#txtCor" + letter;

        if ($(txtCorId).text() === "DA") {
            $("#inputRasCor").val($("#txtRas" + letter).text());
            $("#inputCor").val($(txtCorId).text());
        }
    }
});

Hi, Please try like below

$("#btnVerTest").on("click", function () {
    const letters = ['A', 'B', 'C']; // Array of letters

    for (let i = 0; i < letters.length; i++) {
        const id = "txtCor" + letters[i];

        if ($("#" + id).text() == "DA") {
            $("#inputRasCor").val($("#txtRas" + letters[i]).text());
            $("#inputCor").val($("#" + id).text());
        }
    }
});

I am sorry that I do not have the exact code to solve your problem but it is possible to convert a letter to a number and a number to a letter as in the following.
```
let out = "";
for (let i = 'a'.charCodeAt(0); i <= 'c'.charCodeAt(0); i++) {
  out += String.fromCharCode(i) + " ";
}
message.innerHTML = out;
```
In the C language and most languages like C, it is very easy to convert a letter to a number and a number to a letter because in C and C++ they are the same thing. JavaScript makes it too complicated.
