EmberJS-Binding Element Attributes

Binding Element Attributes

The HTML elements attribute in the template that are bound to the controller are known as binding element attributes.

<script type="text/x-handlebars">
   {{bind-attr controller}}
</script>

The above syntax describes that the bind-attr tag helps to bind controllers.

Example

<!DOCTYPE html>
<html>
   <head>
      <title>Emberjs Binding Element Attributes</title>
      <!-- CDN's-->
      <script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/3.0.1/handlebars.min.js"></script>

   <body>
      <script type="text/x-handlebars">

         <h3 {{bind-attr style="App.priority"}}>
            Warning Message!
         </h3>
      </script>

      <script type="text/javascript">
