Question

当我实例化模型的新实例时，我经常遇到错误。任何人都可以监视错误吗？

Uncaught TypeError: Object [object Object] has no method 'apply'

脚本：

(function() {
    var Ticket = new Backbone.Model.extend({
        urlRoot: "/api/tickets",
        Subject: "",
        Created: null
    });

    var TicketView = new Backbone.View.extend({
        Model: Ticket,
        el: "body",
        render: function() {
            return this.$el.html(this.Model.Subject);
        }
    });

    // Error here
    var t = new Ticket();
    var tv = new TicketView({ model: t });

    tv.render();

})()

HTML：

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>

        <script type="text/javascript" src="/Scripts/Home_Index.js"></script>

</html>
