我尝试将Backbone.js用于我的一个项目,但是使用视图事件时遇到了问题。
HTML文件:
<html>
<head>
<script type="text/javascript" src="underscore-min.js"></script>
<script type="text/javascript" src="backbone-min.js"></script>
<script type="text/javascript" src="model.js"></script>
</head>
<body>
<div id="app">
</div>
</body>
</html>
model.js代码是
window.onload = function() {
var MyModel = Backbone.Model.extend({
defaults: {
name: "Test"
}
});
var MyView = Backbone.View.extend({
tagName: "li",
events: {
"click li": "Show"
},
render: function() {
this.el.innerHTML = this.model.get("name");
},
Show: function() {
alert(this.model.get("name"));
}
});
var model = new MyModel();
var view = new MyView({model: model});
view.render();
document.getElementById("app").appendChild(view.el);
}
我没有错误,但“li”点击时不会触发“显示”功能。有什么问题?
答案 0 :(得分:2)
问题是你将click事件绑定到(不存在的)&#34;&#34;元素的子元素,而不是li元素本身。试试这个:
var MyView = Backbone.View.extend({
tagName: "li",
events: {
"click": "Show"
},
render: function() {
this.el.innerHTML = this.model.get("name");
},
Show: function() {
alert(this.model.get("name"));
}
});
