Adding attributes to input element in Handlebars (

Question

Let's say I have something like:

{{input value=someModel }}

And then I want to add the simple required HTML 5 attribute to the input.

How would I do that?

---

Note that I tried the following variations without success:

{{input value=someModel required }} <!-- doesn't parse -->

{{input value=someModel required='required' }} <!-- doesn't render the attribute -->

{{view Ember.TextField valueBinding=someModel 
    required='required' }} <!-- doesn't render the attribute -->

<input required {{bindAttr value=someModel}}
     /> <!-- doesn't update the model, as expected -->

---

Update: This question was for Ember 1.0.

Answer 1

To globally add support for additional attributes you can reopen Ember.TextField

Answer 2

I'm using Ember version 1.5.1 and required="required" seems to work fine now. This markup:

{{input class="form-control" value=firstName autofocus="autofocus" required="required"}}

...renders this:

<input id="ember392" class="ember-view ember-text-field form-control" autofocus="autofocus" required="required" type="text">

Answer 3

First you need to add support to the required attribute:

Ember.TextSupport.reopen({  
    attributeBindings: ["required"]  
}) 

Then in your view:

{{view Ember.TextField required="required"}}
