# Action
A simple component to perform an Action.
Whether that 'action' be visiting a web page, navigating to a section of a
Javascript application via the History API or dispatching a javascript
event/Ember action. It doesn't matter, just use `Action`.
**Note: You should use this for all links/buttons throughout the UI.** (apart from
links that are part of i18n translations, you'll know which ones these are as
they are in translation files, not handlebars templates) Many components export
a slightly more configured Action contextual component which will be this
component with a few more HTML attributes applied.
You don't need to worry/think about which native tag to use the component will
use the semantically correct tag depending on whether you give it a href
argument or not.
If you give the Action a `href` then that will navigate you to that hyperlink
reference (semantically this is the same as the HTML Anchor tag, and
semantically renders as one).
```hbs preview-template
Click Me
```
If you don't give the `Action` a `href` then the action you are performing will
not be navigation you to a hyperlink reference and instead performing the action
specified, generally using the `on` modifier (semantically this is the same as
a HTML button tag, and semantically renders as one).
```hbs preview-template
Click Me: {{if this.boolean 'On' 'Off'}}
```
We currently have a handy shortcut to tag the Action as an `external` hyperlink
reference. The following will add the necessary attributes for you for an
`external` link so you don't have to. This is likely to be handled automatically
in the future.
```hbs preview-template
Click Me
```
## Arguments
| Argument | Type | Default | Description |
| :-------- | :------ | :-------- | :------------------------------------------------------------- |
| href | string | undefined | Clicking the Action will take the user to the specified href |
| external | boolean | false | Sets the href as an external link that will be treated as such |
