Angularjs - 如何在数组和本地存储中存储对象

How I can store multiple objects into an array and then into local storage so that I can get all objects when required using a loop.

我如何将多个对象存储到一个数组中,然后存储到本地存储中,这样我就可以在需要时使用循环获取所有对象。

example objects:

var newMsg = {
      sentDate: msgDate,
      sentTime: msgTime,
      msgTitle: "message title",
      msgDesc: "message desc"
    };

Currently I'm using https://github.com/grevory/angular-local-storage#configuration-example angularjs module but struggling to store and retrieve objects from an array.

目前我正在使用https://github.com/grevory/angular-local-storage#configuration-example angularjs模块,但很难从数组中存储和检索对象。

I have tried the following code:

我试过以下代码:

msgArray = [];
var savedMsgs = localStorageService.set("wimmtkey", newMsg);

    msgArray.push(savedMsgs); 
    console.log(savedMsgs);

This outputs 'true' in the console but expecting to see the stored object. Please also advise to loop through the array to retrieve the objects. Thanks.

这在控制台中输出'true'但期望看到存储的对象。还请建议循环访问数组以检索对象。谢谢。

Some more code would be useful but for angular-local-storage this is the way that you push objects into array before saving the array in the localStorage:

一些更多的代码将是有用的,但对于角度局部存储,这是在将对象保存到localStorage之前将对象推送到数组中的方式:

var msgArray = [];
var newMsg = {
    sentDate: msgDate,
    sentTime: msgTime,
    msgTitle: "message title",
    msgDesc: "message desc"
};

//you can push all the objects here before saving to the storage
//maybe you have a forEach here, pushing the objects? Who knows
msgArray.push(newMsg); 

//the array is now set in the storage
localStorageService.set("wimmtkey", msgArray); 

//the array obtained from local storage
var obtained_array = localStorageService.get("wimmtkey");
