Why is my input value variable empty when retrieving it after user input?

Troubleshooting Empty Input Value Stored in Variable

When attempting to retrieve the value of an input field () for later use in fetching data from an API, you may encounter an issue where the stored variable remains empty regardless of the user's input. This occurs because the variable holding the input value is initialized only once during initial script evaluation, never to be updated again.

In your provided code snippet, the inputValue variable is assigned the value of the input field when the script is first loaded, not when the button is clicked. To access the updated input value each time the button is clicked, you have two options:

1. Query the Element Every Time:

const testing = () => {
  const inputValue = document.getElementById("inputField").value;

  alert(inputValue);
};

In this case, the input value is retrieved and used within the testing function every time it is called.

2. Reference the Element and Query the Value Property:

const inputElement = document.getElementById("inputField");
const testing = () => alert(inputElement.value);

Here, the input element reference is stored in inputElement, allowing you to access its value property whenever needed.
