Ember Checkbox getting name of element in callback - ember.js

Question

If I define a checkbox as follows:
{{input type="checkbox" name="email" checked=controller.isEmailChecked}} Email
In the callback controller.isEmailedChecked, defined as:
isEmailChecked: function(key, value) {
...
}
How do I get the value of name ("email")?
My controller is responsible for displaying multiple checkboxes so I do not want to have to write lines like this:
{{input type="checkbox" name="x" checked=controller.isXChecked}} X
{{input type="checkbox" name="y" checked=controller.isYChecked}} Y
Only to be doing:
ixXChecked: function(key, value) {
// Set or Get
this.set('x', value);
this.get('x');
}
ixYChecked: function(key, value) {
// Set or Get
this.set('y', value);
this.get('y');
}
Can someone point me to the docs please.
Edit: Same applies to actions on Buttons:
<button {{action 'toggleSetting'}}>
</button>
How would I get the name of the element in the toggleSetting callback?
Thanks a lot,

Answer 1

Thanks albertjan but this is more simple:
{{view Ember.Checkbox checkedBinding=someModelProperty}}
It updates the someModelProperty when clicked, and it also sets the correct value initially.

You can pass a parameter to a action like this: {{action "post" "test"}} where the second test can also be a variable. {{action "post" mail}}
As for the checkboxes I'd solve that with an item controller:
{{#each thing in things itemController='thing'}}
{{input type="checkbox" checked=onChecked}}
{{/each}}
and your controller would looks something like:
App.ThingController = Ember.Controller.extend({
needs: ['parent'] //where parent is the name of your other controller.
action: {
isChecked: function() {
this.get('contollers.parent')
.send('checkboxChecked', this.get('model.name'));
}
}
});
Or you can add a component, lets call it named-checkbox. And that would look something like this:
Template (app/templates/components/named-checkbox.hbs):
{{input name=name type="checkbox" checked=onChecked}}
{{yield}}
Component (app/components/named-checkbox.js):
import Ember from 'ember';
import layout from '../templates/components/named-checkbox';
export default Ember.Component.extend({
layout: layout,
name: "",
action: {
onChecked: function() {
this.sendAction(this.get('action'), this.get('name'));
}
}
});
Then you can use it like this:
{{named-component name="email" action=isChecked}}
This will result in the isChecked action being called on the controller with the name as it's attribute:
actions: {
isChecked: function(name) {
this.set('name', !this.get('name'))
}
}
