backbone.jsHow can I use a template in Backbone.js?

Backbone.js provides a powerful way to use templates in your application. Templates are used to generate HTML from your model data.

To use a template in Backbone.js, you need to first create a template using a templating language like Underscore.js. For example, the following template creates a list of items from a model:

  <% _.each(items, function(item) { %>
    <li><%= item.name %></li>
  <% }); %>

Once the template is created, you can use the Backbone.View object to render the template. The render() method of the View object takes the model data and passes it to the template. For example:

var view = new Backbone.View({
  model: items

view.render = function() {
  return this;

The render() method takes the model data as an argument and passes it to the template. The template is then rendered to the $el property of the view.

You can also use a pre-compiled template, which is a template that has already been compiled into JavaScript code. This can be done using a templating library like Handlebars.js.

Finally, you can also use a template engine such as Mustache.js to create and render templates in Backbone.js.

Code explanation

  1. <ul> - This is the start tag for an unordered list.
  2. <% _.each(items, function(item) { %> - This is an Underscore.js loop that iterates through the items in the model and creates a list item for each item.
  3. <li><%= item.name %></li> - This is a list item tag that displays the item's name.
  4. <% }); %> - This is the end tag for the Underscore.js loop.
  5. var view = new Backbone.View({ - This creates a new Backbone.View object.
  6. model: items - This sets the model data for the view.
  7. view.render = function() { - This is the render() method for the view.
  8. this.$el.html(this.template(this.model.toJSON())); - This takes the model data and passes it to the template.
  9. return this; - This returns the view object.
