如何在頁面加載時爲選擇框設置默認選項?我試過在下面的例子中設置selectedPersonController的默認值,但無濟於事。難道我做錯了什麼?Ember.Select默認選項
var App = Ember.Application.create();
App.Person = Ember.Object.extend({
id: null,
firstName: null,
lastName: null,
fullName: function() {
return this.get('firstName') + " " + this.get('lastName');
}.property('firstName', 'lastName').cacheable()
});
App.selectedPersonController = Ember.Object.create({
person: null
});
App.peopleController = Ember.ArrayController.create({
content: [
App.Person.create({id: 1, firstName: 'Yehuda', lastName: 'Katz'}),
App.Person.create({id: 2, firstName: 'Tom', lastName: 'Dale'}),
App.Person.create({id: 3, firstName: 'Peter', lastName: 'Wagenet'}),
App.Person.create({id: 4, firstName: 'Erik', lastName: 'Bryn'})
]
});
模板:
{{view Ember.Select
contentBinding="App.peopleController"
selectionBinding="App.selectedPersonController.person"
optionLabelPath="content.fullName"
optionValuePath="content.id"}}
對不起,只是一個錯字。這正是我所期待的。謝謝! – skinneejoe 2012-03-17 01:47:17
