Retrieving and Updating Form Input Values
Learn how to efficiently get and set the current values of HTML form input fields using JavaScript for interactive forms.
const inputField = document.getElementById('myInputField');
// Get the current value
const currentValue = inputField.value;
console.log('Current value:', currentValue);
// Set a new value
inputField.value = 'New Data';
console.log('Updated value:', inputField.value);
How it works: This snippet demonstrates how to access and modify the value property of an input element. It first retrieves the element by its ID, then reads its current value, and finally assigns a new string to its value property, effectively updating the content displayed in the input field.
