Question

使用Ember，我正在尝试构建一个表单，并在商店中填充<select>个下拉列表。我不知道如何从这里恢复一个值，以便在＆＃34; save＆＃34;功能

我做错了什么？

以下是我所拥有的简化版本：

route访问不同模型。这很好用：

import Ember from 'ember';
export default Ember.Route.extend({

    model() {
        var store = this.store;

        return Ember.RSVP.hash({
            fighters: store.findAll('fighter'),
            duels:store.findAll('duel')
        });
    },

    setupController(controller, models) {

        var fighters = models.fighters;
        var duels = models.duels;

        controller.set('fighters', fighters);
        controller.set('duels', duels);
   }
});

Controller应使用表单的值保存新的决斗。这里＆＃34; formdata＆＃34;表单提交时为null

import Ember from 'ember';
export default Ember.Controller.extend({

    actions: {
        save(formdata) {
             var newduel = this.store.createRecord('duel', {
                  fighter1:formdata.fighter1,
                  fighter2:formdata.fighter2,
             });             
        }
    }
});

模板显示下拉列表确定，但我无法连接＆＃34;到控制器中的值，无论我尝试##FIGHTERn##！

 <form {{action "save" formdata on "submit"}}>
<dl>
    <dt>
        <select value='##FIGHTER1##'>
            {{#each fighters as |fighter|}}
                <option value={{fighter.id}}>{{fighter.name}}</option> 
            {{/each}}
    </select>            
    </dt>

    <dt>
       <select value=##FIGHTER2##>
            {{#each fighters as |fighter|}}
                <option value={{fighter.id}}>{{fighter.name}}</option> 
            {{/each}}
        </select>  
    </dt>
</dl>
<button type="submit">Add</button>

AsyncLayoutInflater inflater = new AsyncLayoutInflater(getActivity());
do {
    inflater.inflate(R.layout.xxx, gridLayout, new AsyncLayoutInflater.OnInflateFinishedListener() {
        public void onInflateFinished(View view, int resid, ViewGroup parent) {
            //some logic
            parent.addView(view);
            Log.d(TAG, parent.getChildCount() + " " + parent.getWidth() + "x" + parent.getHeight());
        }
    });
} while (cursor.moveToNext());

控制器：

<form {{action "save" formdata on "submit"}}>
<dl>
    <dt>
        <select onchange={{action (mut fighter1) value="target.value"}}>
            {{#each fighters as |fighter|}}
                <option value={{fighter.id}} selected={{is-equal fighter1 fighter.id}}>{{fighter.name}}</option> 
            {{/each}}
    </select>            
    </dt>

    <dt>
       <select onchange={{action (mut fighter2) value="target.value"}}>
            {{#each fighters as |fighter|}}
                <option value={{fighter.id}} selected={{is-equal fighter2 fighter.id}}>{{fighter.name}}</option> 
            {{/each}}
        </select>  
    </dt>
</dl>
<button type="submit">Add</button>
