Question

NodeJs :(服务电话）

router.route('/getProAtribute')
.post(function(req,res,next){
ProductData.find({},{'_id':0,'attribute':1},function(err,productDatas){
if(!err){res.json(productDatas);}
else{res.json({'status':'no data or error'});}
});
});

架构：

var product_schema = new mongoose.Schema({
product_id:{type:Number},
product_name:{type:String},
product_image:{type:String},
product_image_type:{type:String},
category_id:{type:Number},
category_name:{type:String},
attribute:{type:[]}
})
var ProductData = module.exports = mongoose.model('productData', product_schema);

JSON输出：

[{"_id":"5693413efc055b0011ac7891","attribute:[{"Size":"asd","Brand":"asds","product_id":"1"}]},{"_id":"569cb82c079bfa80094dc936","attribute":[{"Size":"SA","Brand":"123","product_id":"2"}]}]

注意：属性键会动态变化（大小，颜色，类型，价格等......）

所以我需要在前端打印密钥和值。

试试这个

<div ng-repeat="(key,value) in data">
{{value._id}}
<div ng-repeat="(key,values) in value.attribute">
{{values.Size}}  {{values.Brand}}
Key: {{key}}
</div>
</div>

OR

<div ng-repeat="value in data">
{{value._id}}
{{value.attribute[0].Size}}<!--For static you can use $index in place of 0-->
</div>

如何使用AngularJS访问此JSON数据？
