有一个带有 backbone.js 的简单模板 -
jsTemplateBackbone.html
<html>
<head>
<script src="jquery-2.1.0.min.js"></script>
<script src="json2.min.js"></script>
<script src="underscore.js"></script>
<script src="backbone.js"></script>
<!--Order is important !!!-->
</head>
<body>
<script type="text/template" id="item-container">
<li><%= value %></li>
</script>
<script src="jsBackboneHomeView.js"></script>
</body>
</html>
jsBackboneHomeView.js
//Model
Wine = Backbone.Model.extend();
// Collection
Wines = Backbone.Collection.extend({
Model: Wine,
url: "#"
});
// Collection object
wines = new Wines([
{ name: "Robert Mondovi" },
{ name: "CakeBread" }
]);
// List
ListView = Backbone.View.extend({
tagName: 'ul',
initialize: function () {
// grabing the html template
this.template = _.template($('#item-container').html());
},
render: function () {
var el = this.$el, template = this.template;
el.empty();
wines.each(function (wine) {
el.append(template(wine.toJSON()));
});
return this;
}
});
// View
HomeView = Backbone.View.extend({
el: 'body',
initialize: function () {
this.render();
},
render: function () {
this.$el.empty();
this.$el.append("<h1>My App</h1>");
listView = new ListView();
// append two <li> on <ul> and return it
this.$el.append(this.listView.render().el);
return this;
}
});
// View instance
wineApp = new HomeView();
当我执行它时，它给出了一个错误 -
Uncaught TypeError: Cannot call method 'replace' of undefined - underscore.js:1236
line 1236 - text.replace(matcher, function(match, escape, interpolate, evaluate, offset) {
这里出了什么问题？

最佳答案
模型中的属性称为name，而模板中的属性称为value，因此无法替换。尝试:
<li><%= name %></li>
在您的模板中。
