Identifying the pressing of the enter key in an input field

Question

Identifying the pressing of the enter key in an input field

Currently, I am developing an innovative IFrame browser that features an omnibox (identified as "address") and a "GO" button (identified as "submit"). One of the key challenges I'm facing is detecting when the user inputs information and hits the Enter key, triggering a specific JavaScript function. I experimented with utilizing the <form> tag and sought guidance from various resources like the W3Schools How TO - Trigger Button Click on Enter. However, my attempts with the form tag led to complications within my application, and the method of triggering the button click on Enter did not yield the desired outcome.

Below is a snippet of the code I've been working with:

<!DOCTYPE html>
<html lang="en">
<head>
     <!--- Code snippet goes here --->
</head>
<body>
     <!--- Additional code snippet goes here --->
</body>
</html>

Your assistance and time in resolving this matter would be greatly appreciated. Thank you for your support!

Answer №1

Here is an example of how you can achieve this:

const inputElement = document.getElementById("enter-input");

inputElement.addEventListener("keyup", handleEnter);

function handleEnter(event) {
  event.preventDefault();
  if (event.keyCode === 13) {
    console.log("hello");
  }
}

<form onsubmit="event.preventDefault();" action="">
  <input id="enter-input" type="text" />
</form>

Try clicking on the input and pressing enter to see a console log. Pressing any other key will not trigger the console log.
