我仍在学习Ember,并且在显示/隐藏模板中的某些元素时遇到了保持一致行为的问题。我有以下控制器
import Ember from 'ember';
export default Ember.ArrayController.extend({
actions: {
newCalendar: function() {
this.set('showCalendarForm', true);
},
hideNewCalendar: function() {
this.set('showCalendarForm', false);
this.set('calendarName', '');
},
showCalendarForm: false,
createCalendar: function() {
var name = this.get('calendarName');
if (!name) { return; }
if (!name.trim()) { return; }
var calendar = this.store.createRecord('calendar', {
name: name
});
this.set('calendarName', '');
this.set('showCalendarForm', false);
calendar.save();
},
}
});
和模板
{{#if showCalendarForm}}
<div class="input-group">
{{input
class = 'form-control'
id = 'newCalendar'
type = 'text'
placeholder = 'New calendar'
value = calendarName
autofocus = 'autofocus'
focus-out = 'hideNewCalendar'
action = 'createCalendar'
}}
</div>
{{else}}
<button class="btn btn-sm btn-primary" {{action "newCalendar"}}>New</button>
{{/if}}
问题是输入字段仅在我第一次单击按钮时才会自动聚焦,在后续点击时,输入会显示,但不会自动聚焦。我该如何解决这个问题?
