![]() So if in the future the column object carries a new property, a new attribute will be assigned to the component, without having to change the template explicitly. That will assign each property in the column object to the attribute in the component with that same name. React's JSX on the other hand, has a syntax for this purpose: We'd have to go over every place where this component is used, and add the new attribute explicitly. Right now I have to repeat every attribute explicitly, as in: īesides being too verbose, this has a fundamental flaw: imagine if a new attribute is added to the component in the future. In Ember.Component the classNames, classNameBindings and attributeBindings properties are concatenated. To clarify, I'll be more explicit about my current situation. īut could I do it if I wanted the properties of the column object to be passed as attributes to this component? React.js, for instance has a notation for this. attributes to it.I'd like to pass the properties of an object as attributes of a component.įor instance, in the example below, I'm passing the object as an attribute column of the dynamic-table-column component. For example, Ember components having an implicit wrapper element, and Ember automatically applying. For instance, in the example below, I'm passing the object as an attribute column of the dynamic-table-column component. This is when the framework does something for you that you have no insight into, so you may not understand what is happening or why. Handlebars.js: Pass object properties as Ember.js component attributes Asked 7 years, 6 months ago Modified 7 years, 5 months ago Viewed 1k times 1 I'd like to pass the properties of an object as attributes of a component. attributes in our Glimmer component, we need to update how we're calling the component:Ī common point of dissatisfaction with frameworks, including Ember, is the so called "magic". In this case we do not want to pass class as an HTML attribute when calling the component because class is special in that it merged together the existing classes in the component with whatever you pass to the component: // app/components/my-button.hbsįor the sake of exemplifying attributeBindings I glossed over the fact that Ember will apply any HTML attributes you pass to an Ember component to the implicit wrapper element. attribute we are telling Ember where to put any HTML attributes that are passed in when calling the component. ![]() extend ( we are saying that the value should be primary if is not defined, and in. ![]() One of the first proposals for Ember components had actions defined as a member function of the component, like so: export default Component. How you define the component actions also requires an adjustment. Now you should use native getters and setters, as well as tracked properties. With the new Glimmer component implementation you are expected to use the native class syntax, but it also changes something more important: a Glimmer component no longer inherits from EmberObject. The first thing that catches the eye is that Glimmer components have a different base class with a radically different API (see Ember Component vs Glimmer component).
