我使用主干的插件backbone.validation进行模型字段验证。我喜欢插件引入的很好的声明性验证方式。我缺少的是验证不是特定领域的方法,而是整个模型。这就是我想要的:
var SomeModel = Backbone.Model.extend({
validation: {
field1: {
required: true
},
field2: {
required: true
},
field3: {
required: true
}
'whole model': function () {
// this method makes some complex validation logic and expected to be
// called each time the validation of model (some fields) is performed
}
}
});
当我不使用backbone.validation插件时,我可以很容易地做到这一点,但是当我使用它时怎么做呢?

你可以这样做,见这里:https://github.com/thedersen/backbone.validation#validate
"You can also call it manually without any parameters to validate the entire model."
插件会在幕后覆盖Backbone.Model.prototype.validate。如果您声明了所有规则并致电modelInstance.validate()
,则应验证所有属性。
