Backbone.js集合的获取方法用于使用sync方法获取集合中的默认模型集。
句法：
collection.fetch(options)参数说明
选项：它指定“成功”或“错误”回调，它们都将作为参数传递。
让我们以一个示例来部署fetch方法。
请参阅以下示例：
<!DOCTYPE html>
<head>
<title>Fetch 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 represents state of a model
Backbone.sync = function(method, model) {
//The 'method' gives 'read' state of the model by representing data in JSON format
document.write("The fetched details are: ", method + ": " + JSON.stringify(model));
};
//The collection instance 'details' contains the values which are to be fetched in the collection
var details = new Backbone.Collection({
Name:"Narendra Modi", Country:"India"
});
//This will display the model state by delegating the 'sync()' method
details.fetch();
</script>
</body>
</html>输出：
将上面的代码保存在fetch.html文件中，然后在新的浏览器中打开该文件。
