I think this source code speaks for itself, it creates a new view. Every time I find a tutorial there is this return value on the render function. But I never understood what it does, my code always worked with or without that return value, what does it exactly do?
// renders individual todo items list (li)
app.TodoView = Backbone.View.extend({
tagName: 'li',
template: _.template($('#item-template').html()),
render: function(){
this.$el.html(this.template(this.model.toJSON()));
return this; // "enable chained calls" whatever that means
}
});
It does what you say, it enables chain calls that means you can invoke multiple method calls.
The most common use I've seen in Backbone it's calling el
after render
.
var view = new TodoView();
('#todo').append(view.render().el);
But you could create any other method in your view and chain it together.
view.render().method1().method2()
