如何用JSON中的空元素表示数组? [英] How to represent an array with empty elements in JSON?

问题描述

我在JavaScript中有一个看起来像这样的数组:

I have an array in JavaScript that looks like this:

var pattern = [ ["C5", 3], , , , , , , , ["C5", 3], , , ] 

我想将其存储在这样的json文件中:

I want to store it in a json file like this:

{
  "pattern": [
               ["C5", 3], , , , , , , , ["C5", 3], , ,
             ]
}

JSONLint告诉我这一点:

JSONLint tells me this:

Parse error on line 6:
...        ],        ,        ,        
---------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['

所以我知道我不能让逗号之间的空格为空.类似于空，但被JSON标准接受了吗?

So I understand I can't let the space between commas empty. What's similar to empty, but is accepted by JSON standards?

此模式文件是我正在制作的Javascript音乐跟踪器的一部分，与脉冲跟踪器相似，我希望json文件尽可能整洁.

This pattern file is part of a Javascript Music Tracker I'm making that's similar to impulse tracker, and I want the json file to be as clean as possible.

推荐答案

如果要在JSON中保留空白，则应使用null填充它.

If you want to have empty space in JSON, you should fill it with null.

示例:

var pattern = [ ["C5", 3], null, null, null, null, null, null, null, ["C5", 3], null, null, null, null, ...... ]
