Answer: Use the value property of the input element.
When working with forms in JavaScript, one common task is to retrieve the value entered by the user in an input field. This can be done by accessing the input element and then using the value property to get the value entered by the user.
Here is a simple example:
“`javascript
// Get the input element
var inputElement = document.getElementById(‘myInput’);
// Get the value entered by the user
var inputValue = inputElement.value;
// Print the value to the console
console.log(inputValue);
“`
By using the value property of the input element, you can easily retrieve the value entered by the user and use it in your JavaScript code.
