Input Helpers
The {{input}} and {{textarea}} helpers in Ember.js are the easiest way to
create common form controls. The {{input}} helper wraps the built-in
Ember.TextField and Ember.Checkbox views, while {{textarea}} wraps
Ember.TextArea. Using these helpers, you can create these views with
declarations almost identical to how you'd create a traditional <input> or
<textarea> element.
Text fields
{{input value="http://www.facebook.com"}}
Will become:
<input type="text" value="http://www.facebook.com"/>
You can pass the following standard <input> attributes within the input
helper:
| `readonly` | `required` | `autofocus` |
| `value` | `placeholder` | `disabled` |
| `size` | `tabindex` | `maxlength` |
| `name` | `min` | `max` |
| `pattern` | `accept` | `autocomplete` |
| `autosave` | `formaction` | `formenctype` |
| `formmethod` | `formnovalidate` | `formtarget` |
| `height` | `inputmode` | `multiple` |
| `step` | `width` | `form` |
| `selectionDirection` | `spellcheck` |
If these attributes are set to a quoted string, their values will be set directly on the element, as in the previous example. However, when left unquoted, these values will be bound to a property on the template's current rendering context. For example:
{{input type="text" value=firstName disabled=entryNotAllowed size="50"}}
Will bind the disabled attribute to the value of entryNotAllowed in the
current context.
Actions
To dispatch an action on specific events, such as enter or key-press, use the following
{{input value=firstName key-press="updateFirstName"}}
Event Names must be dasherized.
Checkboxes
You can also use the {{input}} helper to create a checkbox by setting its
type:
{{input type="checkbox" name="isAdmin" checked=isAdmin}}
Checkboxes support the following properties:
checkeddisabledtabindexindeterminatenameautofocusform
Which can be bound or set as described in the previous section.
Text Areas
{{textarea value=name cols="80" rows="6"}}
Will bind the value of the text area to name on the current context.
{{textarea}} supports binding and/or setting the following properties:
