它是被自动通过Backbone生成的,所以该模型可以被唯一地标识在客户端上的客户端ID。
model.cid
<!DOCTYPE html>
<head>
<title> Model Example</title>
<script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script>
<script type="text/javascript">
var Person = Backbone.Model.extend();
var person = new Person();
document.write("<b> Before setting unique identifier of model Person : </b>",person.id);
document.write("<br>");
document.write("<b> Before setting unique identifier of model Person, CID: </b>",person.cid);
document.write("<br>");
var person = new Person({id: 1});
document.write("<b> After setting unique identifier of model Person : </b>",person.id);
document.write("<br>");
document.write("<b> After setting unique identifier of model Person, CID: </b>",person.cid);
</script>
</head>
<body></body>
</html>
