Question

我有一个对象在发生某些数据更改时会更新，我需要将之前的数据存储到数组中并在需要时检索它

/* currently i could get 1 data i need multiple data stored to a storage as array*/
    get(){
        this.storage.get('uploaded').then((data) => {
            console.log("get data", JSON.parse(data));        
        });
    }

    set(){
        var obj = { upload: true,
                    file: file.audio //this will hold an object which vary when required
                  }

        this.storage.set('uploaded', JSON.stringify( obj ));
    }

您可以使用数组的 push（）方法使用新数据更新数组。

var obj = new Array();
obj.push();// use this whenever you have new data

并使用它来访问值

for (var i in obj) {
   //access values using obj[i]
}

使用新对象更新数组
