更新与新对象的数组

Question

我有当过一些数据发生改变时它获取更新的对象，我需要到以前的和更新的数据存储到一个数组并检索它需要的时候

/* 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)); 
    } 

Answer 1

你可以使用push（）数组的方法用新数据更新数组。

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] 
}
