将数据保存到本地存储 [英] Save data to local storage

问题描述

我正在尝试在本地存储中设置一组变量，但函数没有运行，我试图获得值，但没有运气，如何在本地存储中保存字段？

I'm trying to set a bush of variables in local storage but the function doesn't run, I've tried to get the value but without luck, How can I save fields in Local storage?

function setPerson(){
var person = { 'name': getElementById('name'), 'photo': getElementById('photo')};

// Put the object into the storage
    alert(person);
    localStorage.setItem('person', JSON.stringify(person));
};

HTML
在HTML中我来自字段放将值放入标签中并填充它们，但是当我尝试获取它们并保存它们时，没有任何事情发生...

HTML In the HTML I'm from fields put values into tags and they are populated, but when I try to fetch them and save them nothing is happening...

我还尝试在那里输出固定值，然后显示警报，但是它只显示对象而不是值

I also tried to out fixed values in there and then the alert is displayed, but then it only says object and not the value

var testObject = { 'one': 1, 'two': 2, 'three': 3 };

// Put the object into storage
localStorage.setItem('testObject', JSON.stringify(testObject));

// Retrieve the object from storage
var retrievedObject = localStorage.getItem('testObject');
alert('retrievedObject: ', JSON.parse(retrievedObject));;

推荐答案

您可以像这样使用localStorage：

You can use localStorage like this:

// Retrieve your data from locaStorage
var saveData = JSON.parse(localStorage.saveData || null) || {};

// Store your data.
function saveStuff(obj) {
  saveData.obj = obj;
  // saveData.foo = foo;
  saveData.time = new Date().getTime();
  localStorage.saveData = JSON.stringify(saveData);
}

// Do something with your data.
function loadStuff() {
  return saveData.obj || "default";
}
