我的验证函数没有在下面的代码中被调用:-
var Vehicle = Backbone.Model.extend({
color: 'green',
validate: function (attrs) {
var validColors = ['white', 'red', 'blue', 'yellow'];
var colorIsValid = function (attrs) {
if (!attrs.color) return true;
return _.contains(validColors, attrs.color);
}
if(!colorIsValid(attrs)) {
return "color must be one of: " +validColors.join(",");
}
}
});
var car = new Vehicle();
car.on('error', function (model, error) {
console.log(error);
});
console.log(car.get('color'));
car.set('color', 'muave');

有人能告诉我为什么没有调用验证函数吗?
