Get The Value Of Input Text When Enter Key Pressed

Have you ever been working on a web project and wanted to capture the value of an input text field when the Enter key is pressed? It's a common need for many developers, especially when dealing with forms or search functionalities. In this article, we'll explore how you can easily achieve this functionality using JavaScript.

To start off, let's set up a basic HTML structure with an input text field:

Now, let's write the JavaScript code to capture the input value when the Enter key is pressed. We will add an event listener to the input field to listen for the 'keypress' event and check if the pressed key is the Enter key (key code 13). Here's the code snippet to achieve this:

const inputField = document.getElementById('myInput');

inputField.addEventListener('keypress', function(event) {
  if (event.keyCode === 13) {
    const enteredValue = inputField.value;
    console.log(enteredValue); // You can do whatever you want with the value here
  }
});

In the code above, we first get a reference to the input field using `document.getElementById('myInput')`. We then add an event listener for the 'keypress' event, which triggers the specified function whenever a key is pressed while the input field is focused.

Inside the event listener function, we check if the key code of the pressed key is equal to 13, which corresponds to the Enter key. If the condition is met, we capture the current value of the input field using `inputField.value` and store it in the `enteredValue` variable.

You can replace `console.log(enteredValue)` with any action you want to perform with the captured value, such as submitting a form, triggering a search function, or updating the UI.

With this simple JavaScript code snippet, you can easily get the value of an input text field when the Enter key is pressed. It's a practical solution that can enhance the user experience and streamline the interaction in your web applications.

Remember to test your implementation thoroughly across different browsers to ensure compatibility and a seamless user experience. Happy coding!
