I would like to use a code when I press the space bar a shape appears and it disappears when I press it again. I'm trying to get the addEventListener to work with a sample:
hello = document.querySelector('#Player');
with player being the id of the shape that I want to control. I declared hello above and initialized it in setup (I am using JavaScript), the Player id has also been initialized in HTML and given a shape in CSS. When I use
hello.addEventListener('keypress', (event) => {
console.log(event.key)
})
nothing happens, but when I use
window.addEventListener('keypress', (event) => {
console.log(event.key)
})
it works. Is there anything that I am doing wrong?
That's what should happen.
You can add the keypress event to the window or document.
And, if you add it to both, the window wins over for some reason – someone else might clarify this to both of us.
const el = document.getElementById("el");
el.addEventListener("keypress", event => keyPressed(event, "blue"));
document.addEventListener("keypress", event => keyPressed(event, "green"));
window.addEventListener("keypress", event => keyPressed(event, "purple"));
function keyPressed(event, color) {
if (event.key = " ")
el.style.backgroundColor = color;
}#el {
width: 100px;
height: 100px;
background: red;
}<div id="el"></div>It is because by default div is not selectable. In order to make it selectable you need to use tabindex attribute on your div. It will make your div selectable.
const hello = document.querySelector('#player');
hello.addEventListener("keypress", evt => {
console.log(evt.key)
})<div id="player" tabindex="0">
Player Shape
</div>It will show a boundary around your div which can be remove by using css -
outline: none;
