I want when i click in each one of them to pop the span element with class color but only for that button.
[![enter image description here][1]][1]
I only achieved when i click on one of them to change the visibility to visible on all elements with class colors.
my Code : https://jsbin.com/govowakasa/edit?js
document.getElementById("btn-apple").addEventListener("click", function(e) {
showColor()
});
function showColor() {
const colors = document.getElementsByClassName("color");
for (let i=0; i<colors.length; i ) {
colors[i].style.visibility = 'visible';
}};
CodePudding user response:
You can simply add this line
fruits[i].style.backgroundColor = 'red'
CodePudding user response:
You can not use the same ID
for more than 1 element.
I replaced the IDs of buttons with a new class name fruit-btn
.
Then I made an array in JS of both buttons and color spans.
Then I looped through each button to add an EventListener
.
In the event I added another loop that hides every color span and then makes the i
span visible. There is no need for a function.
const fruit_btn = document.getElementsByClassName("fruit-btn");
const color_spans = document.getElementsByClassName("color");
for (let i = 0; i < fruit_btn.length; i ) {
fruit_btn[i].addEventListener("click", function(e) {
for (let i = 0; i < fruit_btn.length; i ) {
color_spans[i].style.visibility = "hidden";
}
color_spans[i].style.visibility = "visible";
});
}
body {
font-size: 2rem;
}
li {
margin: 20px;
list-style: none;
}
button i {
cursor: pointer;
font-size: 3rem;
}
.color {
margin: 10px;
border: 1px solid black;
background-color: blanchedalmond;
display: inline-block;
padding: 10px;
visibility: hidden;
}

I would suggest to add/remove a Class instead of adding/removing directly CSS styling.
