如何使用Ionic Native Storage存储阵列数据？ [英] How to Store Array Data Using Ionic Native Storage?

问题描述

我计划使用离子本机存储来存储一些翻译历史记录，只要有翻译的单词。翻译操作（日期，翻译单词）将存储在离子原生存储中，当我打开历史页面时，将显示翻译历史列表。

I'm planning to use ionic native storage to store some translation history, whenever there's a word being translated. The translation action (date, translate word) will be store in the ionic native storage, and when I open history page, a list of translation history will be shown.

这里是我从离子官方网站获得的最基本的代码：

Here's the most basic code I got from the ionic official website:

export class HomePage {
  DataArray: Array<string> = [];

  constructor(public navCtrl: NavController, private storage: Storage) {

  }
  // set a key/value
  setData(){
  this.storage.set('age', 'Max');
  }
  // Or to get a key/value pair
  getData(){
  this.storage.get('age').then((val) => {
    console.log('Your age is', val);
  });
}
}

推荐答案

使用 getItem 和 SetItem

export class HomePage {
  DataArray: Array<string> = [];

  constructor(public navCtrl: NavController, private storage: NativeStorage) {

  }
  // set a key/value
  setData(){
  this.storage.setItem('keyOfData', JSON.stringify(DataArray));
  }
  // Or to get a key/value pair
  getData(){
  this.storage.getItem('keyOfData').then((val) => {
    console.log('Your age is', JSON.parse(val));
  });
}
}
