我刚刚开始我的 Backbone 教程，在第一次作业时我必须在页面上显示一点 ul。我写了下面的代码，浏览器没有显示任何错误，但也没有在屏幕上显示列表。有人可以检查我的代码，我哪里做错了。

var SongsView = Backbone.View.extend({
render: function(){
var self = this;
this.model.each(function(song){
var songView = new SongView({ model: song });
self.$el.append(songView.render().$el);
});
}
});
// Adding Data to Models.
var songs = new Songs([
new Song({title: "This is title One"}),
new Song({title: "This is Title Two"}),
new Song({title: "This is title third"})
]);
var Object_SongsView = new SongsView({el: "songs", model: songs});
Object_SongsView.render();
</script>

最佳答案
应该像这样创建 View (注意 songs 的 CSS 选择器前面的 #):
var Object_SongsView = new SongsView({
el: "#songs",
model: songs
});
关于javascript - 将数据传递给 Backbone Js 中的 View 在浏览器中看不到，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27650640/
