如何将选定的HTML转换为Json？

我想将部分html代码保存为json作为文件,然后重新记录html代码进行编辑.知道我该怎么办？

    

        New Text
        
        

    

我是json的新手,请尽可能简化.我看过其他问题,但他们似乎没有解决我的问题

你想要做的是称为序列化.

//  This gives you an HTMLElement object
var element = document.getElementById('TextBoxesGroup');
//  This gives you a string representing that element and its content
var html = element.outerHTML;       
//  This gives you a JSON object that you can send with jQuery.ajax's `data`
// option, you can rename the property to whatever you want.
var data = { html: html }; 

//  This gives you a string in JSON syntax of the object above that you can 
// send with XMLHttpRequest.
var json = JSON.stringify(data);
