Backbone.BootstrapModal

  • Takes care of instantiation and opening/closing modals
  • Manages multiple modals
  • Adds several options
  • Removes the element from the DOM when closed

##Usage

var view = new Backbone.View({...});

var modal = new Backbone.BootstrapModal({ content: view }).open();

##Events

###cancel The user dismissed the modal (e.g. pressed cancel or Esc etc.)

###ok The user clicked OK

###shown Fired when the modal has finished animating in

###hidden Fired when the modal has finished animating out

##Events in the view You can listen to the events triggered by the modal inside the Backbone.View

var MyView = Backbone.View.extend({
    initialize: function () {
        this.bind("ok", okClicked);
    },

    okClicked: function (modal) {
        alert("Ok was clicked");
        modal.preventClose();
    }
});

var view = new MyView();

var modal = new Backbone.BootstrapModal({ content: view }).open();

##Methods

###new Backbone.BootstrapModal(options) Set up the modal with the following options:

  • {String|View} [options.content] Modal content. Default: none
  • {String} [options.title] Title. Default: none
  • {String} [options.okText] Text for the OK button. Default: 'OK'
  • {Boolean} [options.focusOk] Wether the 'OK' button should have the focus or not. Default: true
  • {Boolean} [options.okCloses] Wether the modal should close on 'OK' click or not. Default: true
  • {String} [options.cancelText] Text for the cancel button. Default: 'Cancel'. If passed a falsey value, the button will be removed
  • {Boolean} [options.allowCancel] Whether the modal can be closed, other than - OK. Default: true
  • {Boolean} [options.escape] Whether the 'esc' key can dismiss the modal- true, but false if options.cancellable is true
  • {Boolean} [options.animate] Whether to animate in/out. Default: false
  • {Function} [options.template] Compiled underscore template to override the default one
  • {Object} [options.modalOptions] Options to pass directly to bootstrap-modal
  • {Boolean} [options.enterTriggersOk] Whether the 'enter' key will trigger OK. Default: false

###modal.open([cb]) Renders and opens the modal, running the optional callback if the 'OK' button is pressed

###modal.close() Close the modal and remove it from the DOM

###modal.preventClose() Prevents the modal from closing. Can be called from within a 'ok' or 'cancel' event listener:

var modal = new Backbone.BootstrapModal().open();

modal.on('ok', function() {
  //Do some validation etc.
  if (!isValid) modal.preventClose();
});
