copied!<p>From the docs: <a href="http://backbonejs.org/#Model-validate" rel="nofollow">http://backbonejs.org/#Model-validate</a>:</p> <blockquote> <p><code>isValidmodel.isValid()</code></p> <p>Models may enter an invalid state if you make changes to them silently ... useful when dealing with form input. Call <code>model.isValid()</code> to check if the model is currently in a valid state, according to your validate function.</p> </blockquote> <p>also from <a href="https://github.com/thedersen/backbone.validation#what-gets-validated-when" rel="nofollow">https://github.com/thedersen/backbone.validation#what-gets-validated-when</a></p> <blockquote> <p>What gets validated when?</p> <p>If you are using Backbone v0.9.1 or later, all attributes in a model will be validated. However, if for instance name never has been set (either explicitly or with a default value) that attribute will not be validated before it gets set.</p> <p>This is very useful when validating forms as they are populated, since you don't want to alert the user about errors in input not yet entered.</p> <p>If you need to validate entire model (both attributes that has been set or not) you can call <code>validate()</code> or <code>isValid(true)</code> on the model.</p> </blockquote> <p>The Backbone-Forms docs specifically mention model.validate:</p> <p><a href="https://github.com/powmedia/backbone-forms#model-validation" rel="nofollow">https://github.com/powmedia/backbone-forms#model-validation</a></p> <p>You could easily hook model.Validate up to whatever edit events or click events you want.</p> <p>Also, you might find this useful (not sure if it is compatible with Backbone.Forms though):</p> <p><a href="https://github.com/thedersen/backbone.validation" rel="nofollow">https://github.com/thedersen/backbone.validation</a></p>
