我对Rails TodoList应用程序有以下视图。没有javascript错误。我甚至可以通过.fetch()方法看到/ todos的GET请求。问题是,没有调用addOne函数,因此没有查看更新。
$(function(){
Todos = new TodoList.Collections.Todos;
TodoList.Views.TodoView = Backbone.View.extend({
tagName: "li",
events: {},
initialize: function(){},
template: _.template('<li> {{task }}</li>'),
render: function(){
var todo = this.model.toJSON();
//return this.template(todo);
return "blah";
}
});
TodoView = TodoList.Views.TodoView;
TodoList.Views.AppView = Backbone.View.extend({
el: $("#todo_app"),
events: {
"submit form#new_todo": "createTodo"
},
initialize: function(){
_.bindAll(this, 'addOne', 'addAll','render');
Todos.bind("add", this.addOne);
Todos.bind("refresh", this.addAll);
Todos.bind("all", this.render);
Todos.fetch();
},
addOne: function(todo){
var view = new TodoView({model: todo});
this.$("#todo_list").append(view.render().el);
alert("here");
},
addAll: function(){
Todos.each(this.addone);
},
newAttributes: function(event){
var new_todo_form = $(event.currentTarget).serializeObject();
return {
dog: {
name: new_todo_form["todo[task]"],
age: new_todo_form["todo[done]"]
}
};
},
createTodo: function (e){
e.preventDefault();
var params = this.newAttributes(e);
Dogs.create(params);
}
});
});
另外,我尝试使用
手动调用它this.addOne({task: "blah", done:"true"});
初始化函数中的。这会引发javascript错误,说toJSON函数未定义。

我认为您写了一个拼写错误并写了refresh
而不是reset
。事件为reset
,因此您必须替换此行:
Todos.bind("refresh", this.addAll);
使用:
Todos.bind("reset", this.addAll);
