我正在尝试使用 Backbone.js,只是试图让消息在我的控制台屏幕上弹出。但是,每次我这样做时,都会不断出现错误(如下所述)
Uncaught TypeError: Expecting a function in instanceof check, but got [object Object] backbone.js:1032
_.extend.setElement backbone.js:1032
_.extend._ensureElement backbone.js:1104
Backbone.View backbone.js:986
child backbone.js:1531
(anonymous function) pageLoader.js:19
(anonymous function)
这是JavaScript文件
(function ($){
window.PageLoader = Backbone.View.extend({
el: $("section"),
events: {
"": "initialization",
"click #aboutUs" : "aboutUs",
},
initialization: function(){
console.log('pageLoader.js initialized\nHome page rendered');
},
aboutUs:function(){
console.log('About us page rendered.');
}
});
var pageLoader = new PageLoader();
//pageLoader.initialization();
//pageLoader.aboutUs();
})(jQuery);
这里也是HTML
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/main.css">
<meta />
<meta />
<title>Bus tours and tows</title>

<body>
