我正在尝试学习 backbone.js(Backbone.js 1.0.0)这是我使用集合的示例 html 页面。 fetch() 方法获取集合，并使用 View 显示它。我正在获取结果 谷歌浏览器，但在 mozilla 中没有任何显示。我不知道确切的原因。
虽然我指的是 backone 网站 http://backbonejs.org/#Collection-fetch
有人说:
请注意，不应使用 fetch 在页面加载时填充集合——加载时需要的所有模型都应该已经引导到位。 fetch 旨在为不需要立即使用的界面延迟加载模型:例如，包含可以打开和关闭的笔记集合的文档。
这与我的问题有关吗？
这是我的示例 html 页面

//Person Model
var Person = Backbone.Model.extend({

});
// A List of People
var PeopleCollection = Backbone.Collection.extend({
model: Person,

// View for all people
var PeopleView = Backbone.View.extend({
tagName: 'table',
render: function(){
this.collection.each(function(person){
var personView = new PersonView({ model: person });
this.$el.append(personView.render().el); // calling render method manually..
}, this);
return this; // returning this for chaining..
}
});
// The View for a Person
var PersonView = Backbone.View.extend({
tagName: 'tr',
template: _.template($('#personTemplate').html()),
////////// initialize function is gone from there. So we need to call render method manually now..
render: function(){
this.$el.html( this.template(this.model.toJSON()));
return this; // returning this from render method..
}
});
var peopleCollection = new PeopleCollection();
//peopleCollection.fetch();
peopleCollection.fetch({ success: function () { console.log("collection fetched"); } });
//peopleCollection.fetch({context:collection}).done(function() {
// console.log(this.length)
// })
//console.log(peopleCollection.toJSON())
alert(JSON.stringify(peopleCollection));
var peopleView = new PeopleView({ collection: peopleCollection });
$(document.body).append(peopleView.render().el); // adding people view in DOM
</script>
</body>
</html>
任何帮助将不胜感激
最佳答案
尝试
var fetching = peopleCollection.fetch({ success: function () { console.log("collection fetched"); } });
$.when(fetching).done(function(){
var peopleView = new PeopleView({ collection: peopleCollection });
$(document.body).append(peopleView.render().el); // adding people view in DOM
});
关于javascript - Backbone 集合。 fetch() 不在 mozilla 中呈现 View ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21773649/
