I have three input fields and one button
1. text
2. time
3. text

BUTTON

These names are: array[]

I want their data to be put into one variable "inputValue" when the click was on the button.

But when I console.log it gives "undefined".

Somebody?

What I have tried:

HTML
<!DOCTYPE html>
<html>
<head>
    <meta charset='utf-8'>
    <meta http-equiv='X-UA-Compatible' content='IE=edge'>
    <title>Value undefined</title>
    <meta name='viewport' content='width=device-width, initial-scale=1'>
</head>
<body>
    <div>
        <h3>To Do </h3>
        <input type="text" id="myInput" name="array[]" placeholder="Write here...">
        <h3>It's time: </h3>
        <input type="time" id="myInput_time" name="array[]" placeholder="Write here...">
        <h3>Description: </h3>
        <input type="text" id="myInput_description" name="array[]" placeholder="Write here...">
        <button onclick="getInputs()" class="addBtn">ADD</button>
    </div>
    <script>
        function getInputs(){
            let inputValue = document.getElementsByName("array[]").value
            console.log(inputValue)
        }
    </script>
</body>
</html>

JavaScript
let inputValue = document.getElementsByName("array[]").value
You cannot do that. You have to enumerate the list of controls returned by getElementsByName and get the .value of each control separately, appending that value to your result string.
JavaScript
let inputs = document.getElementsByName("array[]");
inputs.forEach(c => inputValue = inputValue + ";" + c.value);

But, it would be better to scrap the "array[]" name for every input and just use individual names for each input, preferably names that describe what the input is for.
