FormWrapper component

The idea behind the FormWrapper is to have a black box that validates views for us.

FormWrapper works by taking a view (ItemView, CollectionView or CompositeView) as input, and giving back another view that you can then call render or show on.

Dependencies

• Backbone.Validation
• Backbone.Syphon

Prerequisites

In case you pass an ItemView:

• needs to have a model bound to it
• the Model needs to specify validation rules using Backbone.Validation
• every field that you want to validate needs to have a name property that matches the property name in the model

Example

Template:

<input type="text" name="firstName" />
<input type="text" name="lastName" />

Model:

var Model = Backbone.Model.extend({
  validation: {
    firstName: {
      rangeLength: [1, 28]
    },
    lastName: {
      rangeLength: [1, 29]
    }
  }
});

In case you pass a CollectionView or CompositeView:

Every childView needs to respect the rules mentioned for the ItemView.

How to use it

In case you pass an ItemView:

var viewToValidate = new Marionette.ItemView.extend({
  model: new Model()
});

var formWrapper = new FormWrapper({
  contentView: viewToValidate
});

formWrapper.render();

Options

These are the options accepted by the constructor:

• contentView (Object, default: undefined, required: true)

The instance of the view that you want to validate.

• noHtml5Validate (Boolean, default: true, required: false)

Adds the novalidate attribute to the form element and prevent the validation of the new HTML5 input types.
