I'm new to Ember.js. I want to focus on TextField(in sample, id="text") after initialization, but in ready function, doesn't work focus method...
<body>
<!-- library load -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script>!window.jQuery && document.write(unescape('%3Cscript src="js/libs/jquery-1.6.1.min.js"%3E%3C/script%3E'))</script>
<script src="http://cloud.github.com/downloads/emberjs/ember.js/ember-0.9.5.min.js"></script>
<script type="text/x-handlebars">
{{view Em.TextField id="text"}} // want to focus it.
</script>
<script type="text/javascript">
var App = Em.Application.create();
App.ready = function() {
$('#text').focus(); // does'nt work.
}
</script>
</body>

The following code does work:
<script type="text/x-handlebars">
{{view App.TextField id="text"}} // want to focus it.
</script>
<script type="text/javascript">
var App = Em.Application.create();
App.TextField = Em.TextField.extend({
didInsertElement: function() {
this.$().focus();
}
});
</script>
Subclassing TextField and then spreading a custom View around your templates seemed a bit messy to me, so I wrote this little 1kb package that lets you do this more elegantly, directly in the template, without any further coding:
<body>
<!-- all the libraries -->

<script src="http://cdnjs.cloudflare.com/ajax/libs/handlebars.js/1.3.0/handlebars.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/ember.js/1.2.0/ember.min.js"></script>
<script src="http://rawgithub.com/AndreasPizsa/ember-autofocus/master/dist/ember-autofocus.min.js"></script>
<!-- your template -->
<script type="text/x-handlebars">
Hello, world! {{ input }}
:
: more elements here
:
{{ autofocus }} {# <<<<-- Magic happens here #}
</script>
<!-- your app -->
<script>
Ember.Application.create();
</script>
</body>
You can get it from https://github.com/AndreasPizsa/ember-autofocus
or with bower install ember-autofocus. I appreciate feedback!
