[英]How do I deal with this error with Backbone Router?
This is my application.js file这是我的 application.js 文件
window.App = {
init: function() {
this.router = new PackageViewer();
Backbone.history.start();
}
};
This is calling the other packageviewer.js that's here这是调用这里的另一个 packageviewer.js
window.PackageViewer = new Backbone.Router.extend({
routes : {
'':'home'
},
initialize:function(){
this.collection = new Package();
},
home:function(){
$('body').append("<h1>Welcome</h1>");
}
});
And here is my index.html's script tag that is inside <body>
这是我在
<body>
中的 index.html 的脚本标签
<script type="text/javascript">
$(document).ready(function (){
App.init();
});
</script>
When I run this I get TypeError: 'undefined' is not a function (evaluating 'parent.apply(this, arguments)')
当我运行这个时,我得到
TypeError: 'undefined' is not a function (evaluating 'parent.apply(this, arguments)')
I cannot comprehend this.我无法理解这一点。 Help!
帮助!
Change this:改变这个:
window.PackageViewer = new Backbone.Router.extend({
routes : {
'':'home'
}
to this:对此:
window.PackageViewer = Backbone.Router.extend({
routes : {
'':'home'
}
Because here you're supposed to be just extending Backbone.Router, not creating a new instance.因为在这里您应该只是扩展 Backbone.Router,而不是创建新实例。
You correctly create a new instance in your App.init when you call `this.router = new PackageViewer();当您调用 `this.router = new PackageViewer(); 时,您在 App.init 中正确创建了一个新实例;
I tested this with a dummy Package Model and Collection and it worked.我用一个虚拟 Package Model 和 Collection 对此进行了测试,它工作正常。
window.Package = Backbone.Model.extend({
});
window.Packages = Backbone.Collection.extend({
model: Package
});
