使用Backbone.sync持久化一个集合的状态到服务器。
collection.sync(method, collection, options)
<!DOCTYPE html>
<head>
<title>Collection 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>
</head>
<body>
<script type="text/javascript">
//The sync() method reads and fetches the model data
Backbone.sync = function(method, model) {
document.write("The state of the model is:");
document.write("<br>");
//The 'method' specifies state of the model
document.write(method + ": " + JSON.stringify(model));
};
//The 'myval' is collection instance and contains the values which are to be fetched in the collection
var myval = new Backbone.Collection({
site:"YiiBai",
title:"Simply Easy Learning..."
});
//The myval.fetch() method display the model's state by delegating the sync() method
myval.fetch();
</script>
</body>
</html>
让我们进行以下步骤来看看上面的代码工作：
保存上述代码在文件sync.html
在浏览器打开这个HTML文件。
