将名称属性添加到Ember.TextField？ [英] add a name attribute to a Ember.TextField?

问题描述

这是一个漫长的一天，这可能是非常简单的，但是如何添加一个名称属性到Ember.TextField？

我想做这样的事情：

  {view Ember.TextField valueBinding =your_nameplaceholder =Your namename =your_name}} 
  

与占位符配合使用，但忽略名称。

任何想法？

谢谢
Rick

解决方案

p> name属性未被默认绑定，请参阅

作为解决方法，您可以创建自己的 TextField ，请参阅 http://jsfiddle.net/fkPzr/

  App.TextField = Ember.TextField.extend（{
 init：function（）{
 this._super（）; 
 //获取attributeBindings并添加'name'
 var attributeBindings = this.get（'attributeBindings'）; 
 attributeBindings.pushObject（'name'）; 
 this.set（'attributeBindings'，attributeBindings）; 
} 
}）;

更新

由于 attributeBindings 被声明为连接属性 *可以简化TextField，请参阅 http://jsfiddle.net/cRhcg/ ：

  App.TextField = Ember。 TextField.extend（{
 attributeBindings：['name'] 
}）; 
  

*连接的属性不会覆盖扩展对象的属性，而是覆盖超级对象的现有值被连接起来说得通？以下是示例

Its been a long day and this is probably extemely simple but how do i add a name attribute to a Ember.TextField ?

I want to do something like this :

{view Ember.TextField valueBinding="your_name" placeholder="Your name" name="your_name"}}

This works with the placeholder but ignores the name.

Any ideas ??

thanks Rick

解决方案

The name attribute is not bound by default, see

As a workaround, you could create your own TextField, see http://jsfiddle.net/fkPzr/

App.TextField = Ember.TextField.extend({
    init: function() {
        this._super();
        // get attributeBindings and add 'name'
        var attributeBindings = this.get('attributeBindings');
        attributeBindings.pushObject('name');
        this.set('attributeBindings', attributeBindings);
    }
});

​UPDATE:

Since attributeBindings is declared as a concatenated property* the TextField can be simplified, see http://jsfiddle.net/cRhcg/:

App.TextField = Ember.TextField.extend({
    attributeBindings: ['name']
});

*a concatenated property does not override the property of an extended object but the existing values from the super object are concatenated. Makes sense? Here's an example
