Description

How can I add a spinning icon to the Kendo UI Button?

Solution

  1. Use the icon option of the Button to define a name of an existing icon in the Kendo UI theme sprite. As a result, the icon is applied as a background image of a span element inside the Button.
  2. Define a spinning keyframe.
  3. Apply the animation on the .k-icon class.
<div id="example">
    <div class="demo-section k-content">
        <button id="primaryTextButton" class="k-primary">Primary Button</button>
    </div>
</div>

<style>
    @-moz-keyframes spin {
        from { -moz-transform: rotate(0deg); }
        to { -moz-transform: rotate(360deg); }
    }
    @-webkit-keyframes spin {
        from { -webkit-transform: rotate(0deg); }
        to { -webkit-transform: rotate(360deg); }
    }
    @keyframes spin {
        from {transform:rotate(0deg);}
        to {transform:rotate(360deg);}
    }

    .k-icon {
        -webkit-animation: spin 2s infinite linear;
        animation: spin 2s infinite linear;
    }
</style>

<script>
    $(document).ready(function() {
        $("#primaryTextButton").kendoButton({
        icon: "refresh"
        });
    });
</script>
