srcmini本文概述
Backbone.js集合的create方法用于在集合中创建模型的新实例。
句法：
collection.create(attributes, options)参数说明
属性：它指定已定义模型的属性。
options：它指定参数（例如id，name等）来创建集合实例。
让我们以一个示例来部署create方法。
请参阅以下示例：

<script type="text/javascript">
//The model 'ModelDemo' uses the sync method to display the model state such as create, read, update etc
var ModelDemo = Backbone.Model.extend({
sync : function (method, model, options) {
document.write(JSON.stringify(arguments));
}
});
//'CollectionDemo' is an instance of the collection
var CollectionDemo = Backbone.Collection.extend({
model : ModelDemo //The model 'ModelDemo' is specified by overriding the 'model' property
});
//'ViewDemo' is the name of the view
var ViewDemo = Backbone.View.extend({
//The instance of the collection 'collectiondemo' is created within the 'initialize()' function
initialize : function () {
var collectiondemo = new CollectionDemo();
collectiondemo.create({
Name:"Narendra Modi", Country:"India"
});
}
});
new ViewDemo(); //The view instance 'ViewDemo' is created using the 'new' keyword.
</script>
</body>

将以上代码保存在create.html文件中，然后在新的浏览器中打开该文件。
