我是Ember.js的新手.我想在初始化后专注于TextField(在示例中,id ="text"),但是在ready函数中,不能使用focus方法...
<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>

以下代码确实有效:
<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>
