我使用Backbone.Validation插件验证简单表单。以下是我的模特
var BuyerModel = Backbone.Model.extend({
defaults: {
name: '',
age: ''
},
validation: {
name: {
required: true
},
age: {
min: 18
}
},
initialize: function () {
_.extend(Backbone.Model.prototype, Backbone.Validation.mixin);
}
});
以下是我的观点
var BuyerModelFormView = Backbone.View.extend({
events: {
'click [name~="save"]': 'save'
},
initialize: function () {
Backbone.Validation.bind(this);
},
template: _.template('\
<form>\
Enter name:\
<input name="name" type="text" value="<%= name %>"><br>\
Enter age:\
<input name="age" type="text" value="<%= age %>"><br>\
<input type="button" name="save" value="Save">\
</form>\ '),
render: function () {
var html = this.template(this.model.toJSON());
$(this.el).html(html);
},
save: function () {
console.log(this.model.toJSON());
this.model.set({
name: $('[name~="name"]').val(),
age: $('[name~="age"]').val()
});
console.log(this.model.toJSON());
}
});
以下是我使用它的方式
var buyerModel = new BuyerModel();
var buyerModelFormView = new BuyerModelFormView({
model: buyerModel,
el: 'body'
});
buyerModelFormView.render();
当我在表单中输入任何内容并点击输入时更新模型但不验证。即使我输入不正确的值模型仍然会更新。
我做错了什么,我该如何解决?
答案 0 :(得分:4)
像这样设置强制验证
this.model.set({
name: $('[name~="name"]').val(),
age: $('[name~="age"]').val()
}, {validate: true});
这是你想要的吗?
因为Model.set有这样的字符串
// Run validation.
if (!this._validate(attrs, options)) return false;
并且
// Run validation against the next complete set of model attributes,
// returning `true` if all is well. Otherwise, fire an `"invalid"` event.
_validate: function(attrs, options) {
if (!options.validate || !this.validate) return true;
因此,如果您没有通过验证 - 它将被忽略
以这种方式检查
$(function(){
var buyerModel = new BuyerModel();
buyerModel.on('change', function(){
console.log('on change', arguments);
});
var buyerModelFormView = new BuyerModelFormView({
model: buyerModel,
el: 'body'
});
buyerModelFormView.render();
});
