Backbone.Modal.js removes boilerplate code and adds default behaviors and interactions. You can create a simple dialog modal or complex wizards with stacked modals on top of each other in a few lines of code.
Backbone.modal.js is built on top of Backbone.js. Make sure you include everything that's needed for Backbone and add Backbone.Modal.js and the CSS files to start playing with it. You can also start out with the examples.
If you'd like to create a stacked modal (multiple modals on top of each other), you'll need to use Backbone.Marionette.js and Backbone.Marionette.Modals.js.
Options can be added when extending from Backbone.Modal like:
prefix (for classnames),
keyControl (disable enter/esc events).
You can bind your views by adding an event handler, just like you would define events in a Backbone.View. You can add additional options to pass along:
view (as Backbone.View or template which is required),
viewOptions (for specific options for that view). By using the
onActive callback, you can see whenever a view is active.
Get the amount of views in a modal.
You don't need the
views to create a modal, you can simply use a template if you just want to show one view. But if you want to create a complex modal, you can combine the
views, but you'll have to define a
All views will be rendered within the viewContainer. Select a container from your template by doing:
You can define an element that will trigger all submit events. This will result in calling
submit and closing the modal.
submitEl you can define an element that will cancel the modal. This will result in calling
cancel and closing the modal.

This method is called when the user submitted the modal.
Returns the index of the current view that is visible.
Call this method to remove all events listerners, modal and internal views.
This method is called when the modal view is destroyed.
When you're using Marionette, you can set a Marionette.Region class as modal region:
Backbone.Marionette.Modals. When showing views in this region, it will behave like you would expect. Adding multiple modals, will result in stacked modals. You can close them individually, or all at once.
Like you'd expect from a region, to render a view. When you already have a modal in there, it will animate differently and stack the modal.
This will destroy the last modal you have in the region.
Useful when you want to destroy all modals at once in this region.
This will let you know how many modals are stacked.
