How to Create a button to execute code when pressing enter or clicking the button?-CodePudding

I have created a button. right now the button only works after clicking the button. what I want to do is, When I press the 'enter' key on the keyboard or click the button my code needs to be executed.

how to do that?

const befoClick= document.querySelector('.befoClick');
const afteClick=document.querySelector('.afteClick');

befoClick.addEventListener('click',()=>{
    afteClick.classList.toggle('clicked'); 
 });

body{
  display: grid;
  place-items: center;
  height:100vh;  
}

button{
  width:200px;
  height:50px;
  font-size:20px;
  cursor: pointer;
  border:none;
   border-radius: 8px;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%); 
}
.befoClick{
  background-color: rgb(74, 74, 255);
}

.afteClick{
   background-color: rgb(67, 255, 77);
  visibility: hidden;
}

.clicked{
    visibility: visible;
}

.bfrClick{
    visibility: hidden;
}

<div class='allBtn'>
<div >
  <button class='befoClick'>CLICK ME</button>
  </div>
<div >
  <button class='afteClick'>CLICKED</button>
  </div>
  
  </div>

Use the keyup event listener and then check the pressed key.

There are two event listeners so, I added a separate function.

const befoClick= document.querySelector('.befoClick');
const afteClick=document.querySelector('.afteClick');

const toggleClass = () => afteClick.classList.toggle('clicked'); 

befoClick.addEventListener('click', toggleClass);
 
document.addEventListener('keyup', (event) => {
  if (event.key === 'Enter') {
    toggleClass();
  }
});

body{
  display: grid;
  place-items: center;
  height:100vh;  
}

button{
  width:200px;
  height:50px;
  font-size:20px;
  cursor: pointer;
  border:none;
   border-radius: 8px;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%); 
}
.befoClick{
  background-color: rgb(74, 74, 255);
}

.afteClick{
   background-color: rgb(67, 255, 77);
  visibility: hidden;
}

.clicked{
    visibility: visible;
}

.bfrClick{
    visibility: hidden;
}

<div class='allBtn'>
<div >
  <button class='befoClick'>CLICK ME</button>
  </div>
<div >
  <button class='afteClick'>CLICKED</button>
  </div>
  
  </div>

we can use an array like ['click', 'keyup] and then use forEach on the array to listen to both Events with the same eventListener.

However, if you use Enter it will trigger the eventListener twice as it recognizes the click and the Enter press itself. As such we need to run the script then also twice.

Then in the actual script, you can use classList.toggle to toggle between a clicked class to apply style changes.

Then you can toggle the textContent of the button between an array aswell.

var eleButton = document.querySelector('.button'),
  buttonText = ['CLICK ME', 'CLICKED'],
  indexButtonText = 0;

['click', 'keyup'].forEach(el => {
  eleButton.addEventListener(el, function(e) {
    changeButton();
    if (e.key == 'Enter') {
      changeButton();
    }
  });
});

function changeButton() {
  indexButtonText = (indexButtonText == 0 ? 1 : 0);
  eleButton.classList.toggle('clicked');
  eleButton.textContent = buttonText[indexButtonText];
}

body {
  display: grid;
  place-items: center;
  height: 100vh;
}

button {
  width: 200px;
  height: 50px;
  font-size: 20px;
  cursor: pointer;
  border: none;
  border-radius: 8px;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  background-color: rgb(74, 74, 255);
}

.clicked {
  background-color: rgb(67, 255, 77);
}

<button class='button'>CLICK ME</button>
