我是Backbone.js的新手,很难获得嵌套视图。触发Login视图的render方法,但不会向DOM添加任何内容。似乎它没有从父视图中看到元素。
elm.views.Navigation = Backbone.View.extend({
render: function () {
this.$el.html(this.template());
new elm.views.Login({model: this.model, el: '#login'});
return this;
},
events: {
'mousedown li': 'mouseDown',
'mouseup li': 'mouseUp',
'click .btn-login': 'login'
},
mouseDown: function (e) {
$(e.currentTarget).addClass('active');
},
mouseUp: function () {
$('li').removeClass('active');
},
login: function () {
$(document).trigger('login');
return false;
}
});
elm.views.Login = Backbone.View.extend({
initialize: function() {
this.render();
},
render: function () {
console.log("login render");
this.$el.html(this.template(this.model.toJSON()));
return this;
},
events: {
'click .login': 'login',
'click .logout': 'logout'
},
login: function (e) {
$(document).trigger('login');
return false;
},
logout: function (e) {
$(document).trigger('logout');
return false;
}
});
回应评论:
导航视图正在路由器的初始化程序中显示:
initialize: function() {
elm.user = new elm.models.Person();
elm.navigationView = new elm.views.Navigation({model: elm.user});
$("#pageContent").html(elm.navigationView.render().el);
},
答案 0 :(得分:2)
您的导航视图适用于分离的DOM节点,这意味着您的登录视图无法找到#login
,因此无法填充。
将容器作为el
参数传递到主视图:
elm.navigationView = new elm.views.Navigation({
model: elm.user,
el: "#pageContent"
});
navigationView.render();

或将您的子元素范围限定为主视图中使用的元素:
elm.views.Navigation = Backbone.View.extend({
render: function () {
this.$el.html(this.template());
new elm.views.Login({el: this.$('#login')});
return this;
}
...
});
