emberjs如何禁用Ember.Select？ [英] emberjs how to disable Ember.Select?

问题描述

我有一个类似的问题

Emberjs - 禁用并启用TextField

所以对于文本字段它是disabledBinding。

so for text field it's disabledBinding.

Ember.Select（下拉栏）怎么样？
i尝试禁用绑定但不起作用。

what about Ember.Select (drop down field)? i tried disabledBinding but it's not working.

谢谢！

推荐答案

它不工作，因为禁用未在 attributeBindings 中定义，请参阅代码。

It's not working because disabled is not defined in attributeBindings, see code.

解决方案是将 Ember.Select 并将禁用扩展到连接的属性* attributeBindings ，请参见 http://jsfiddle.net/pangratz666/wTXfH/ ：

A solution is to extend the Ember.Select and add disabled to the concatenated property* attributeBindings, see http://jsfiddle.net/pangratz666/wTXfH/:

Handlebars ：

<script type="text/x-handlebars" >
    {{view App.Select disabled="true"}}
</script>​

JavaScript ：

App.Select = Ember.Select.extend({
    attributeBindings: ['disabled']
});​

---

* concatenated属性意味着在子类中覆盖此属性不会覆盖这些值，而是从超类中扩展现有的。

---

*concatenated property means, that overwriting the this property in a subclass does not overwrite the values, but extends the existing ones from the super class.
