在JavaScript中创建JSON [英] Creating JSON in javascript

问题描述

如何在javascript中将此数据编码为JSON?

How should I encode this data as JSON in javascript?

我使用javascript获取照片上任意数量的标签".每个标签都有以下形式的名字和姓氏:

I use javascript to get an arbitrary number of 'tags' on photos. Each tag has a firstname and a lastname in this form:

firstname = 'john';
lastname  = 'doe';

firstname = 'jane';
lastname  = 'smith';

我想将此数据编码为JSON，使用Ajax将其发送到我的服务器，并在PHP中对其进行解码.

I want to encode this data as JSON, send it to my server with Ajax, and decode it in PHP.

我的想法是创建一个多维数组.有更好的方法吗?

My thought was to create a multidimensional array. Is there a better way to do this?

JSON.stringify()的输出为[{\"firstname\":\"John\",\"lastname\":\"Doe\"},{\"firstname\":\"Jane\",\"lastname\":\"Smith\"}].如何让JSON.stringify()不能转义所有引号?

The output of JSON.stringify() is [{\"firstname\":\"John\",\"lastname\":\"Doe\"},{\"firstname\":\"Jane\",\"lastname\":\"Smith\"}]. How can I have JSON.stringify() not escape all of the quotes?

推荐答案

JSON受JavaScript对象语法的启发，因此您所需要做的就是创建对象数组:

JSON is inspired by JavaScript's object syntax, so all you need to do is create an array of objects:

var data = [
  {
    firstname: 'john',
    lastname: 'doe'
  },
  {
    firstname: 'jane',
    lastname: 'smith'
  }
]

var json = JSON.stringify( data ); // send this object to server
