json不允许评论本身。推理是完全愚蠢的, 因为你可以使用json自己来创造评论, 这完全排除了推理, 并且毫无理由地在完全相同的结果和潜在问题上加载采集数据空间, 比如: 带有评论的json文件。

如果您试图在(使用 / 或 / * * * 或 ) 中发表评论, 那么某些剖析器将会失败, 因为严格来说这不在json 的规格之内 。 所以您不应该这样做 。

例如,在这里,我的图像操作系统保存了图像标记和一些基本格式化(注释)信息(底部):

至少这是我在Json. org的一眼 所经历的

json的语法在那一页上被视觉化了。

确定您可以对 json 进行评论。 从 javascript 读取 json 注释文件, 您可以在解析前删除评论( 参见下面的代码) 。 我确信这个代码可以改进, 但对于使用常规表达式的人来说很容易理解 。

我使用备受评论的json文件来指定我的合成反射系统 的神经元形状。 我也使用备受评论的json 来储存一个运行中的神经元系统的中间状态。 方便地得到评论。 不要听那些告诉你他们是个坏主意的人。

fetch(filename).then(function(response) {
    return response.text();
}).then(function(commented) {
    return commented.
        replace(/\/\*[\s\S]*?\*\/|([^\\:]|^)\/\/.*$/gm, '$1').
        replace(/\r/,"\n").
        replace(/\n[\n]+/,"\n");
}).then(function(clean) {
    return JSON.parse(clean);
}).then(function(json) {
    // Do what you want with the JSON object.
});

没有。

json is only data. 如果您包含一个注释, 那么它也必须是数据 。

您可以有一个名为“_comment”(或某物)的指定数据元素,该元素应该被使用json数据的应用程序忽略。

您也许最好在生成/接收json的进程中得到评论,因为他们应该知道json数据的预发内容,或者至少知道它的结构。

但如果你决定:

{
   "_comment": "comment text goes here...",
   "glossary": {
      "title": "example glossary",
      "GlossDiv": {
         "title": "S",
         "GlossList": {
            "GlossEntry": {
               "ID": "SGML",
               "SortAs": "SGML",
               "GlossTerm": "Standard Generalized Markup Language",
               "Acronym": "SGML",
               "Abbrev": "ISO 8879:1986",
               "GlossDef": {
                  "para": "A meta-markup language, used to create markup languages such as DocBook.",
                  "GlossSeeAlso": ["GML", "XML"]
               },
               "GlossSee": "markup"
            }
         }
      }
   }
}

*.json文件通常用作配置文件或静态数据,因此需要评论 * 一些像Netbeans这样的编辑在 *.json中接受评论。

问题在于将内容解析到对象上。 解决办法是总是应用清洁功能( 服务器或客户端 ) 。

php /p

 $rgx_arr = ["/\/\/[^\n]*/sim", "/\/\*.*?\*\//sim", "/[\n\r\t]/sim"];
 $valid_json_str = \preg_replace($rgx_arr, '', file_get_contents(path . 'a_file.json'));

手笔

valid_json_str = json_str.replace(/\/\/[^\n]*/gim,'').replace(/\/\*.*?\*\//gim,'')

我刚刚找到了"咕噜咕噜咕噜咕噜声"

“从json那里提取评论, 让你在json档案中使用评论!”
