#Forked:
Forked to work with backbone.js:
-Provides a .now() call to do validation without form submission since in backbone.js most form submissions are handled by custom code instead of its default behavior.
-Provides an .unHappy() callback in the options hash.
-Provides a 'scope' input to take in your backbone view's scoped el.
-Don't revalidate upon blur; do it on submit.
-Clear out old errors.
this.$el.find('#id').isHappy({
unHappy: function() {}, // Callback when validation fails.
scope : this.el // Pass in the scoped el for this validation form
}).now(); // Call now() when you want to run the validation.
#Happy.js – are your forms happy? Just ask 'em!
