ember | Ember Communication Patterns

You just have to identify those elements (and I think you can do so using the class with a css selector), then loop through the elements and append the text to the appropriate array.

That specific button can be located with this XPath:

how about using window.open instead of location.replace

This question was featured on today's episode of May I Ask a Question.

These code examples are from an Octane-style app and have Octane syntax, but the features are available in older Ember versions as well.

Some built-in Ember features will help you out here: Loading and Error Substates and the error event.

First, you need to throw the error. Then you need to add an error action and say what should happen when an error occurs. When your request errors, the error event fires automatically, and you can put your transition code there. The error event handling is a feature of Ember routes.

You can define a variable allMatched and increment its value whenever a match is found. Then in the resetBoard function, you can check for a condition whether the allMatched is equal to half of the card's length and then run the audio.

Yes, you can use conditionals in the template. However, the syntax you use will not work as Ember defines a restricted and strict syntax for templates for better understanding.

Ember exposes helpers to perform functions like this in the template. You can create a new helper to check if the two properties are equal like:

This can not work because the glimmer rendering engine (which is used by ember) does not operate on strings. Instead your ember templates are compiled to a binary format during the build, and later at the runtime glimmer will directly produce DOM, not an HTML string.

This means you can never pass a glimmer template around as a string. You could bundle the template compiler with your app (but you should not) to compile the template in the browser, but even then you can not use it to produce an HTML string representation because in this step you loose information (for example action binding). This is because these action bindings are never part of the HTML, but glimmer directly attaches event listeners to the DOM nodes during rendering. By using a HTML string and {{{...}}} you render plain HTML, not a glimmer template, and so this wont work.

What you should do is move all your HTML to templates and use a component to embed it.

The only other possibility is to utilize did-insert from ember-render-modifiers to manually attach an event. so you could do this:

Apparently you want to call the searchuser action on the component without need to click the button on the component, i.e. when the component is shown. Use the did-insert modifier for that.

Usuall that goes like this: you put the modifier on a tag in a component. In your case the or searchbutton would do.

I would recommend to not extend a component in Ember Octance by extending from it's JavaScript class. Instead invoke the component in the template of the wrapping component:
