更新與新對象的數組

Question

我有當過一些數據發生改變時它獲取更新的對象，我需要到以前的和更新的數據存儲到一個數組並檢索它需要的時候

/* 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（）數組的方法用新數據更新數組。

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

並使用它來訪問值

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