Sk-spinner css class about render_async

[omnikron]

In case anybody finds it useful, I am using this spinner, saved in app/assets/images/spinner/gif:

with this in a .scss file:

.sk-spinner-double-bounce.sk-spinner {
  background-image: image_url("spinner.gif");
  background-size: contain;
  display: inline-block;
  width: 15px;
  height: 15px;
}

This is makes pretty tiny spinners, as I am just loading numbers into a table asynchronously. Works great. Thanks for a really useful gem @nikolalsvk!

@basicBrogrammer sure thing, bring it on :)

You can use similar PR as an inspiration for it.

@basicBrogrammer you are right, there isn't anything in documentation about it.

Before I add CSS to render_async, you can try out this solution if it fits you:

If you want to have a working spinner you can add CSS to your application:

/*
 *  Usage:
 *
 *    <div class="sk-spinner sk-spinner-double-bounce">
 *      <div class="sk-double-bounce1"></div>
 *      <div class="sk-double-bounce2"></div>
 *    </div>
 *
 */
.sk-spinner-double-bounce.sk-spinner {
  width: 40px;
  height: 40px;
  position: relative;
  margin: 0 auto;
}
.sk-spinner-double-bounce .sk-double-bounce1,
.sk-spinner-double-bounce .sk-double-bounce2 {
  width: 100%;
  height: 100%;
  border-radius: 50%;
  background-color: #8BB634;
  opacity: 0.6;
  position: absolute;
  top: 0;
  left: 0;
  -webkit-animation: sk-doubleBounce 2s infinite ease-in-out;
  animation: sk-doubleBounce 2s infinite ease-in-out;
}
.sk-spinner-double-bounce .sk-double-bounce2 {
  -webkit-animation-delay: -1s;
  animation-delay: -1s;
}
@-webkit-keyframes sk-doubleBounce {
  0%,
  100% {
    -webkit-transform: scale(0);
    transform: scale(0);
  }
  50% {
    -webkit-transform: scale(1);
    transform: scale(1);
  }
}
@keyframes sk-doubleBounce {
  0%,
  100% {
    -webkit-transform: scale(0);
    transform: scale(0);
  }
  50% {
    -webkit-transform: scale(1);
    transform: scale(1);
  }
}

Thanks y'all

Didn't realize you were going to work on adding this... I was about to take the css from https://github.com/tobiasahlin/SpinKit and it worked after modifying it a little. I was doing this as a spike so I've deleted that branch already :/

One reason I abandoned the spike was bc one of my partials was a paginated collection. When i clicked to the next page it replaced my entire body with the async partial. Has anyone worked with this already?

[basicBrogrammer]

Hey would y'all be interested in a PR to allow any of the spinkit spinners with a local variable passed to the render_async helper?

• add local variable to partial
• add css for each of the spinners

I've made some changes that lets you pass in your own placeholder. 💪

I've removed the old code that has CSS classes sk-spinner sk-spinner-bounce.

You can checkout how to use your own placeholder in the README
