The Backbone.JS Model() collection method is used to specify the model class.
Syntax:
Backbone.Collection.model
Example:
<title>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 X = Backbone.Model.extend({
defaults: {
name: "Tom",
age: 20
}, });
var Y = Backbone.Collection.extend({
model: X
});
var Z=new Y({});
document.write("Collection: ",JSON.stringify(Z));
</script>Collection: [{"name":"Tom","age":20}]
<title>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 X = Backbone.Model.extend({
defaults: {
name: "Tom",
age: 20
}, });
var Y = Backbone.Collection.extend({
model: X
});
var Z=new Y({});
document.write("Collection: ",JSON.stringify(Z));
</script>Collection: [{"name":"Tom","age":20}]
Example Collection: [{"name":"Tom","age":20}]
Output:
Collection: [{"name":"Tom","age":20}]
Collection: [{"name":"Tom","age":20}]
Collection: [{"name":"Tom","age":20}]
Explanation:
In the above example, the model ‘X’ includes the default values and is extended using the Backbone.Model class, and ‘Y’ is an instance of the collection.
