The Backbone.js clone is used to return the attributes of the given object in JSON format. We have to use JSON.stringify() to return the attributes.
Syntax:
Backbone.Model.toJSON(options)
Parameters:
- options: Used to take the attribute name.
If it is not specified, then it will return the whole model.
Example 1: In this example, we will display all the attributes in a book model.
HTML
<!DOCTYPE html> <html>
<head>
<script src=
type="text/javascript">
</script>
<script src=

<body>
<script type="text/javascript">
var Books = Backbone.Model.extend();
var book = new Books(
{
book_name:"css",
price:900,
type:"web"
});
document.write("Values in book model: ",
JSON.stringify(book));
</script>
</body>
</html>

Output:
Values in book model:
{
"book_name":"css",
"price":900,
"type":"web"
