backbone.jsHow do I create a modal dialog using Backbone.js?
Creating a modal dialog using Backbone.js is relatively easy. The following example code will create a modal dialog:
// Create a new Backbone view
var ModalDialog = Backbone.View.extend({
// Set the template
template: _.template("<div class='modal-dialog'> <div> <h1><%= title %></h1> <p><%= message %></p> </div> </div>"),
// Initialize the view
initialize: function(options) {
this.title = options.title;
this.message = options.message;
},
// Render the view
render: function() {
var html = this.template({
title: this.title,
message: this.message
});
this.$el.html(html);
return this;
}
});
// Create a new instance of the modal dialog
var modal = new ModalDialog({
title: 'My Modal Dialog',
message: 'This is my modal dialog!'
});
// Render the modal dialog
modal.render();
The rendered modal dialog will look like this:
<div class="modal-dialog">
<div>
<h1>My Modal Dialog</h1>
<p>This is my modal dialog!</p>
</div>
</div>
