这很好：

https://github.com/mafintosh/json-markup来自马芬托什

const jsonMarkup = require('json-markup')
const html = jsonMarkup({hello:'world'})
document.querySelector('#myElem').innerHTML = html

HTML

<link ref="stylesheet" href="style.css">
<div id="myElem></div>

样式表示例可在此处找到

https://raw.githubusercontent.com/mafintosh/json-markup/master/style.css

var jsonObj = {"streetLabel": "Avenue Anatole France", "city": "Paris 07",  "postalCode": "75007", "countryCode": "FRA",  "countryLabel": "France" };

document.getElementById("result-before").innerHTML = JSON.stringify(jsonObj);

如果以HTML显示，则应添加应答器<pre></pre>

document.getElementById("result-after").innerHTML = "<pre>"+JSON.stringify(jsonObj,undefined, 2) +"</pre>"

例子：

var jsonObj={“streetLabel”：“Avenue Anatole France”，“city”：“Paris 07”，“postalCode”：“75007”；document.getElementById（“result before”）.innerHTML=JSON.stringfy（jsonObj）；document.getElementById（“resultafter”）.innerHTML=“<pre>”+JSON.stringify（jsonObj，未定义，2）+“</pre>”div｛float:left；clear:both；margin:1em 0；｝<div id=“result before”></div><div id=“result after”></div>

<!-- here is a complete example pretty print with more space between lines-->
<!-- be sure to pass a json string not a json object -->
<!-- use line-height to increase or decrease spacing between json lines -->

<style  type="text/css">
.preJsonTxt{
  font-size: 18px;
  text-overflow: ellipsis;
  overflow: hidden;
  line-height: 200%;
}
.boxedIn{
  border: 1px solid black;
  margin: 20px;
  padding: 20px;
}
</style>

<div class="boxedIn">
    <h3>Configuration Parameters</h3>
    <pre id="jsonCfgParams" class="preJsonTxt">{{ cfgParams }}</pre>
</div>

<script language="JavaScript">
$( document ).ready(function()
{
     $(formatJson);

     <!-- this will do a pretty print on the json cfg params      -->
     function formatJson() {
         var element = $("#jsonCfgParams");
         var obj = JSON.parse(element.text());
        element.html(JSON.stringify(obj, undefined, 2));
     }
});
</script>

更好的方法。

用Javascript美化JSON数组

JSON.stringify(jsonobj,null,'\t')

非常感谢大家！根据前面的答案，这里是另一种提供自定义替换规则作为参数的变体方法：

 renderJSON : function(json, rr, code, pre){
   if (typeof json !== 'string') {
      json = JSON.stringify(json, undefined, '\t');
   }
  var rules = {
   def : 'color:black;',    
   defKey : function(match){
             return '<strong>' + match + '</strong>';

   types : [
       {
          name : 'True',
          regex : /true/,
          type : 'boolean',
          style : 'color:lightgreen;'
       },

       {

       }
    ],

    punctuation : {

          regex : /([\,\.\}\{\[\]])/,
          type : 'punctuation',
          style : function(match){

这是user123444555621的很棒的HTML，适合终端。易于调试节点脚本：

function prettyJ(json) {
  if (typeof json !== 'string') {
    json = JSON.stringify(json, undefined, 2);
  }
  return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, 
    function (match) {
      let cls = "\x1b[36m";
      if (/^"/.test(match)) {
        if (/:$/.test(match)) {
          cls = "\x1b[34m";
        } else {
          cls = "\x1b[32m";
        }
      } else if (/true|false/.test(match)) {
        cls = "\x1b[35m"; 
      } else if (/null/.test(match)) {
        cls = "\x1b[31m";
      }
      return cls + match + "\x1b[0m";
    }
  );
}

用法：

// thing = any json OR string of json
prettyJ(thing);
