Try something like this
const btns = document.querySelectorAll(".btn-post")
btns.forEach(btn => {
btn.onclick = () => btns.forEach(_btn => _btn.className = "btn btn-success")
}).btn-post {
background-color: black;
color: white;
}
.btn-success {
background-color: green;
}<button class="btn-post">Post</button>
<button class="btn-post">Post</button>
<button class="btn-post">Post</button>
<button class="btn-post">Post</button>You can use javascript to do so.
var elems = document.getElementsByClassName("btn-post");
for(var i = 0; i < elems.length; i++) {
elems[i].className = "btn btn-success";
}
You can get all the elements with class bln-post, and create an array from it. You can then edit the class names using classList API.
const elems = document.getElementsByClassName('btn-post')
Array.from(elems).forEach(el => {
el.classList.remove('btn-post');
el.classList.add('btn');
el.classList.add('btn-success');
}).btn-success {
color: green
}<button class="btn-post">Post</button>
<button class="btn-post">Post</button>
<button class="btn-post">Post</button>
<button class="btn-post">Post</button>So I have a few elements:
HTML:
<button class="btn-post">Post</button>
<button class="btn-post">Post</button>
<button class="btn-post">Post</button>
<button class="btn-post">Post</button>
As you can see, these buttons have the class btn-post and when someone clicks a button and activates an event.
I want to replace all the btn-post classes with btn btn-success (btn and btn-success)
Any helpful advice?
Loop through elements selected with
