What is the best way to add bind-attr class to an existing class in Ember framework?

Is there a way to add a dynamic CSS class onto an initial static one using the {{bind-attr}} method?

The problem I am facing is that when there is a static initial class, the dynamic class does not get added when the page loads. However, once I change the variable during the application run, the class binding works as expected.

You can check out an example of this situation in action on this JSFiddle here.

Answer №1

To achieve the desired effect, make sure to implement the syntax as shown below:

<p {{bind-attr class=':bold isRed:red'}}>

For further information, refer to the documentation provided by Ember.js here. Pay close attention to the section that states:

It is not possible to combine bound class names with static class names.
