0.5.3版本对Model数据验证时,绑定Error就可以了:
(function(){
var Model = Backbone.Model.extend({
initialize : function(){
this.bind('error',function(model,error){
alert(error);
});
},
validate : function(attrs){
for (var key in attrs){
if (attrs[key] == ''){
return key + '不能为空';
}
}
}
});
var model = new Model;
model.set({name:''});
model.set({age:''});
})();
1.0.0版本有变化,需要绑定invalid事件,而且要显示声明{validate:true}:
(function(){
var Model = Backbone.Model.extend({
initialize : function(){
this.bind('invalid',function(model,error){
alert(error);
});
},
validate : function(attrs){
for (var key in attrs){
if (attrs[key] == ''){
return key + '不能为空';
}
}
}
});
var model = new Model;
model.set({name:''},{validate:true});
model.set({age:''},{validate:true});
})();
Backbone的例子网上比较少,文档不多,如果突然使用新版文件可能难以找出问题。
