As you can see we have created a box at the top of a web page. When you press a key on your keyboard. Then all the information in the box can be seen.

How to Detect enter key in Javascript

Here you will find complete information and step-by-step tutorials. But to make this detect enter key project you need to have an idea about HTML, CSS, and javascript.

Below the article is a section on copying code. There is also a button to download the source code.

Step 1: Basic area of the project

First I created a box at the top of the web page in which all the information can be found. I have used blue color in the background of the web page and light white color has been used in the background of the box. 

<div class=”container”>
 
</div>
* {
box-sizing: border-box;
margin: 0;
padding: 0;
font-family: “Montserrat”, sans-serif;
}
body {
display: flex;
justify-content: center;
align-items: center;
text-align: center;
min-height: 100vh;
background: #1276d1; /* fallback for old browsers */
 }
.container {
display: flex;
width: 400px;
flex-direction: column;
padding: 2rem;
background: rgba(255, 255, 255, 0.25);
box-shadow: 0 8px 32px 0 rgba(31, 38, 135, 0.37);
backdrop-filter: blur(4px);
-webkit-backdrop-filter: blur(4px);
border-radius: 10px;
border: 1px solid rgba(255, 255, 255, 0.18);
}

Step 2: Display the view of the pressed key

Now another small box has been created in that box in which key-related information can be found. This means that what you press on your keyboard can be seen in that box.

 <div class=”key-container”>
   <p>Press any key</p>
 </div>
.key-container {
display: inline-flex;
font-size: 22px;
flex-direction: column;
font-weight: bold;
padding: 20px;
position: relative;
color: #333;
margin: 2.5rem;
min-width: 150px;
background: white;
box-shadow: 0 8px 32px 0 rgba(31, 38, 135, 0.37);
backdrop-filter: blur(2.5px);
-webkit-backdrop-filter: blur(2.5px);
border-radius: 10px;
border: 1px solid rgba(255, 255, 255, 0.18);
}
Display the view of the pressed key

Step 3: Activate detect pressed key with JavaScript

Now you need to activate it with JavaScript. Very simple JavaScript has been used for this. Here I have tried to explain as much as possible. As a result, you will not have any difficulty in making detect enter key javascript.

//A constant of the basic box has been determined
const container = document.querySelector(“.container”);
//The keydown event is fired when a key is pressed. 
window.addEventListener(“keydown”, (e) => {
//console. log(e) method is used for writing a message in the console
  console.log(e);
//innerHTML property is part of the Document Object Model (DOM)
  container.innerHTML = 
    `<div class=”key-container”><h4>Key</h4>${
      e.key === ” ” ? “Space” : e.key
    }</div> <div class=”key-container”><h4>Code</h4>${
      e.code
    }</div><div class=”key-container”><h4>Key Code</h4>${e.keyCode}</div>`;
 });
detect pressed key with JavaScript

The h4 tag has been designed using some of the following CSS. We have used this h4 tag in JavaScript.

.key-container h4 {
color: #333;
position: absolute;
top: -2rem;
right: 0px;
text-align: center;
width: 100%;
}
