Question

我正在尝试将JSON数据加载到sessionStorage中，稍后可以检索，但无法弄清楚！我想我做错了。是否应该使用其他脚本进行Ajax调用？可以将它放在storeUser函数中吗？

function StoreUser() {
    let user = {
        'id' : 1 ,
        'fisrtName' : 'Alexander',
        'lastName' : 'Udose',
        'email' : 'XXXXXX@yahoo.com',
        'phoneNumber' : '555555555',
        'address' : '200 CrestView Church RD',
        'creditCard' : '4566XXXXXXXXXX',
        'favoriteFoods' : [
            'Okazi Soup',
            'Egusi Soup',
            'Jollof rice'
        ]
    };

    let person = JSON.stringify(user);

    localStorage.setItem('myPerson', person);

     // XHRrequest 
     let xhr;

     if(window.XMLHttpRequest){
         xhr = new XMLHttpRequest();
     } else {
         XHR = new ActiveXObject("Microsoft.XMLHTTP");
     };

      xhr.onreadystatechange = function(){
          if(xhr.readyState == 4 && xhr.status == 200){
              let data = JSON.parse(xhr.responseText);
              console.log(data);
          }
      };

      XHR.open('POST','person')
}

您只需要这些行即可使用localStorage保存和加载序列化对象

localStorage.setItem('myPerson', person); //Saves person to localStorage
person = localStorage.getItem('myPerson');  //Loads person from localStorage
person = JSON.parse(person); //Converts the string back to an object

进行AJAX调用以将JSON数据加载到sessionStorage
