js中的会话存储 [英] Session Storage in js

问题描述

您好，我是JavaScript的初学者，我想问一下是否有可能对我从服务器获取的数据进行会话.我要会话的数据是我在网上搜索的"data.xhr.response"，大多数人都使用SessionStorage函数，但我不确定如何处理它，任何建议都将不胜感激.

Hi i'm a beginner in JavaScript i would like to ask if its possible to session the data i'm getting from a server. The data i want to session is the 'data.xhr.response' i searched online that most people use the SessionStorage function but i'm not really sure how to go about it any suggestion would be appreciated.

$(function() 
{
Dropzone.autoDiscover = false;

$('#file-upload').dropzone({
    maxFiles: 1,
    acceptedFiles: ".pdf,.doc,.docx,.html", 
    dataType: "json",
    success : function(data) {
        console.log(data.xhr.response);

    }
    });
});

推荐答案

会话存储与本地存储相同，但唯一的区别是，一旦页面会话到期，会话存储中的数据将自动清除.

Session storage is same as local storage but the only difference is that data stored in session storage will clear automatically once page session will expire.

现在问您的问题.在您的成功函数中，执行以下操作以存储数据:

Now come to your question. In your success function, do like below to store data:

success : function(data) {
    console.log(data.xhr.response);
    sessionStorage.setItem('dataStored', data.xhr.response);

}

用法如下:

// Save data to sessionStorage
sessionStorage.setItem('dataStored', data.xhr.response);

// Get saved data from sessionStorage
var data = sessionStorage.getItem('dataStored');

// Remove saved data from sessionStorage
sessionStorage.removeItem('dataStored');

// Remove all saved data from sessionStorage
sessionStorage.clear();
