backbone.jsHow do I use Backbone.js to create a Hacker News-style application?
Backbone.js is a JavaScript library that can be used to create a Hacker News-style application. To do this, you'll need to create a model to store data, a collection to store a group of models, and a view to display the data. Here's an example of how to create a model:
var NewsItem = Backbone.Model.extend({
defaults: {
title: '',
content: '',
comments: []
}
});
This creates a model that has three default attributes: title, content, and comments.
Then you'll need to create a collection to store a group of NewsItem models:
var NewsItemsCollection = Backbone.Collection.extend({
model: NewsItem
});
This creates a collection of NewsItem models.
Finally, you'll need to create a view to display the data:
var NewsItemView = Backbone.View.extend({
tagName: 'li',
template: _.template($('#news-item-template').html()),
render: function(){
this.$el.html(this.template(this.model.toJSON()));
return this;
}
});
This creates a view that will render a list item element with the model's data.
To use these components together, you'll need to create an instance of the NewsItemsCollection, add NewsItem models to it, and then create a NewsItemView for each model.
