z22*_*z22 7 jquery-mobile backbone.js
我正在使用带有backbone.js的jQuery Mobile.当我加载主页时,我收到以下错误:
Uncaught TypeError: Cannot call method '_trigger' of undefined
这是我做的加载主页.在routes.js中:
routes:{
'':'home',
}
home:function () {
new HomeView();
this.changePage(new HomeContentView());
},
changePage:function (page) {
$(page.el).attr('data-role', 'page');
console.log($(page.el));
page.render();
$('body').append($(page.el));
var transition = $.mobile.defaultPageTransition;
if (this.firstPage) {
transition = 'none';
this.firstPage = false;
}
$.mobile.changePage($(page.el), {changeHash:false, transition: transition});
}
在view.js中
window.HomeView = Backbone.View.extend({
template : Handlebars.compile($('#home').html()),
render : function (eventname) {
this.$el.html(this.template());
this.header = new HeaderElement();
this.$el.find('div.header_element').append(this.header.$el);
this.footer = new FooterElement();
this.$el.find('div.footer_element').append(this.footer.$el);
return this;
}
});
window.HomeContentView = Backbone.View.extend({
initialize: function(options) {
this.collection = new Fan();
this.template = Handlebars.compile(tpl.get('elements/home'));
//~ console.log(tpl.get('home'));
this.collection.on("reset",this.render,this);
this.init = true;
if (this.init) {
upLimit = 1;
this.collection.index();
this.init = false;
}
},
el: '#home_content_view',
render : function (eventName) {
var self = this;
var js = (self.collection.toJSON())[0];
console.log(js);
$('#home_content_view').html(self.template(js));
$('#home_content_view').trigger("create");
}
});
在home.html
<div data-role="content">
hi
</div>

其他页面正确呈现.只有主页给我带来麻烦.我哪里错了？我该如何解决这个问题？
我认为这个错误可能是因为jQuery Mobile需要一个元素来过渡changePage.这是一个黑客攻击,但在index.html div中将data-role属性设置为"page"时将其解析为:
<body>
<!-- jQM seems to need a page to exist in the document before it transitions to the first dynamically generated one -->
<div data-role="page"></div>
</body>
