When I try to log the value of a text input field to the console, it appears empty. Any idea why this is happening?
<input type="text" id="word"/>
//JavaScript
var userInput = document.getElementById("word").value;
console.log(userInput);

Remember to include an event handler for better functionality.
Attach an onchange event listener to the input element.
function updateText() {
var newText = document.getElementById("text").value;
console.log(newText);
}<input type="text" id="text" onchange='updateText()'/>To populate the input field with a default value or manually enter one is required.
<input type="text" id="word" value="World"/>
var enteredWord = document.getElementById("word").value;
console.log(enteredWord);
The console will display the entered value.
Implement .addEventListener to execute a function when a change event occurs - This function will be triggered whenever the value in the input field is updated and the focus is shifted away from the input box
document.getElementById('word').addEventListener('change', function () {
let newWord = this.value;
console.log(newWord);
});<input type="text" id="word"/>Alternatively, you can utilize the input event, which triggers as soon as the input content is altered
document.getElementById('word').addEventListener('input', function () {
let newWord = this.value;
console.log(newWord);
});<input type="text" id="word"/>It seems that you are looking to retrieve the value from an input box using a function when a specific event occurs. Here is a sample code snippet that demonstrates how this can be achieved:
<!DOCTYPE html>
<html>
<body>
<p>In this example, a function is executed when a key is pressed in the input field.</p>
<input type="text" id="myInput" onkeypress="getValue()">
<p id="output"></p>
<script>
function getValue() {
var inputValue = document.getElementById('myInput').value;
document.getElementById('output').innerHTML = inputValue;
}
</script>
</body>
</html>
