backbone.js Model Creating models
Example
Backbone models describe how data is stored using JavaScript objects. Each model is a hash of fields called attributes and the behaviour of the model including validation is described by options.
A model of Todo item in a TodoApp would be
var ToDo = Backbone.Model.extend({
defaults: {
assignee: '',
task: ''
},
validate: function(attrs) {
var errors = {},
hasError = false;
if(!attrs.assignee) {
errors.assignee = 'assignee must be set';
hasError = true;
}
if(!attrs.task) {
errors.task = 'task must be set';
hasError = true;
}
if(hasError) {
return errors;
}
}
});
