Angular Component

Location: app/assets/javascripts/components.

Basic pattern

A component shouldn't modify any data or DOM that's out of its scope. All communication should go via bindings. One-way binding should be preferred over two-way binding.
Set controllerAs: "vm".
templateUrl: should be preferred over template: but at the moment it's impossible to test that component's HTML is generated correctly if templateUrl: is used. So temporarily template: should be used instead of templateUrl:.

miq-button

Component for a button element.

%miq-button{:name      => t = _('Cancel'),
            :title     => t,
            :alt       => t,
            :enabled   => "true",
            'on-click' => "cancelClicked()"}

%miq-button{:name          => t = _('Validate'),
            :enabledTitle  => validate_title_on,
            :disabledTitle => validate_title_off,
            :enabled       => "true",
            'on-click'     => "cancelClicked(),
            :primary       => "true"}

It consists of:

  • name (String) sets text shown in the button.
  • enabled (expression) sets button to enabled or disabled.
  • enabledTitle (String, optional) used if button has different title/alt for enabled and disabled state. Sets title/alt for enabled button. If enabledTitle is set disabledTitle should be set as well.
  • disabledTitle (String, optional) used if button has different title/alt for enabled and disabled state. Sets title/alt for disabled button. If disabledTitle is set enabledTitle should be set as well.
  • primary (expression, optional) True if button has class btn-primary otherwise it will have class btn-default.
  • onClick (function) is a callback to be called when button is clicked.

If title/alt are the same for both states, title and alt should be set as attributes of the button.
