Trying to display animation on click....not working (js, html, css)-CodePudding

I have a loading element that I want to display on the click of a certain button. I have tried various methods including updating the visibility and display, as well as adding a "show" classList to the div onclick (current code). Nothing has worked so far and I am desperate. I would really appreciate any help. Thanks :)

document.getElementById('text-generate-button').onclick = () => {
  parent.postMessage({
    pluginMessage: {
      type: 'placeholder-frame'
    }
  }, '*')
  const loader = document.getElementById('loader');
  loader.classList.add("show")
}

.loader {
  opacity: 0;
  background: #ffffff;
  /* background: radial-gradient(#222, #000); */
  bottom: 0;
  left: 0;
  right: 0;
  top: 0;
  /* z-index: 99999; */
  -webkit-transform: scale(0.4);
  -moz-transform: scale(0.4);
  -ms-transform: scale(0.4);
  transform: scale(0.4);
}

.loader.show {
  background: #ffffff;
  /* background: radial-gradient(#222, #000); */
  bottom: 0;
  left: 0;
  right: 0;
  top: 0;
  /* z-index: 99999; */
  -webkit-transform: scale(0.4);
  -moz-transform: scale(0.4);
  -ms-transform: scale(0.4);
  transform: scale(0.4);
}

.loader-inner {
  bottom: 0;
  height: auto;
  left: 0;
  margin: auto;
  position: relative;
  right: 0;
  top: 0;
  width: 100px;

CodePudding user response：

I think the problem is that the "show" class you are adding is set to "display: none". Maybe it can help.

CodePudding user response：

I didn't dig deep whether there is a better way but one thing you can do is in your HTML set

<div  id="loader>

and in your JS

 loader.classList.toggle("loader")

here is running version : https://jsbin.com/boromarugo/edit?html,css,js,output

there should be cleaner way but you get the idea
