我正在尝试更改页面并显示带有 JQM 和主干的视图。
我的主页加载正常,但是当我尝试转到第二页时 - 这是我有几个问题的时候。页面加载但没有显示
所以我的应用程序有一个路由器
var AppRouter = Backbone.Router.extend({
//define routes and mapping route to the function
routes: {
'': 'showHome', //home view
'home': 'showHome', //home view as well
'products/productList' : 'showProducts',
},
initialize:function () {
// Handle back button throughout the application
$('.back').live('click', function(event) {
window.history.back();
return false;
});
this.firstPage = true;
},
defaultAction: function(actions){
this.showHome();
},
showHome:function(actions){
// will render home view and navigate to homeView
var homeView=new HomeView();
homeView.render();
this.changePage(homeView, 'fade');
},
showProducts:function(){
var productList=new Products();
var self = this;
productList.fetch({
success:function(data) {
self.changePage(new ProductListView({collection:data}));
}
});
},
changePage:function (view, transition) {
//add the attribute 'data-role="page" ' for each view's div
if (transition != "slidefade") {
transition = "pop";
}
view.$el.attr('data-role', 'page');
$('.ui-page').attr('data-role', 'page');
//append to dom
$('body').append(view.$el);
if(!this.init){
$.mobile.changePage($(view.el), {changeHash:false, transition: transition});
}else{
this.init = false;
}
}
});
$(document).ready(function () {
console.log('App Loaded');
app = new AppRouter();
Backbone.history.start();
});
return AppRouter;
这也是我的产品查看页面
var ProductListView = Backbone.View.extend({
template: _.template(productViewTemplate),
initialize: function () {
_.bindAll(this, "render");
this.collection.bind("reset", this.render);
},
render: function () {
var self = this;
this.collection.each(function(model) {
self.$el.append(self.template(model.toJSON()));
console.log("here");
});
}
});
return ProductListView;
因此,从 homeView 中我可以更改页面,这很好,我在产品视图上做错了什么,因为它不返回任何东西.. 没有返回错误。
谢谢
所以我做了更多的工作并使我的展示产品功能
showProducts:function(){
var productList=new Products();
var self = this;
var productListView =new ProductListView({collection:productList});
productList.fetch(self.changePage(productListView));
}
当视图为
var ProductListView = Backbone.View.extend({
template: _.template(productViewTemplate),
initialize : function () {
_.bindAll(this, "render");
this.collection.bind("reset", this.render, this);
},
render: function() {
var self = this;
this.collection.each(function(model) {
self.$el.append(self.template(model.toJSON()));
console.log("here");
});
}
});
return ProductListView;
但是现在 jQueryMobile 没有添加它的代码,所以它没有样式..
有什么建议么?
