我JSON。Stringify一个json对象
result = JSON.stringify(message, my_json, 2)
上面参数中的2应该是漂亮的输出结果。如果我执行alert(result)之类的操作，它就会这样做。但是，我想通过在div中追加它来将其输出给用户。当我这样做时，我只会显示一行。(我不认为这是工作，因为断点和空格没有被解释为html?)
{ "data": { "x": "1", "y": "1", "url": "http://url.com" }, "event": "start", "show": 1, "id": 50 }
是否有一种输出JSON结果的方法。Stringify到一个div在一个漂亮的打印方式?
当前回答
考虑你的REST API返回:
{"Intent":{"Command":"search","SubIntent":null}}
然后你可以按照下面的步骤打印出来:
<pre id="ciResponseText">Output will de displayed here.</pre>
var ciResponseText = document.getElementById('ciResponseText');
var obj = JSON.parse(http.response);
ciResponseText.innerHTML = JSON.stringify(obj, undefined, 2);
其他回答
如果这确实是为用户准备的，比仅仅输出文本更好，您可以使用像https://github.com/padolsey/prettyprint.js这样的库将其输出为HTML表。
使用样式空白:pre <pre>标记还修改可能不希望的文本格式。
对于那些想要显示可折叠json的人，可以使用renderjson
下面是通过在html中嵌入渲染js javascript的例子

您可以尝试这个存储库:https://github.com/amelki/json-pretty-html
用预标签包装
<pre> { JSON.stringify(todos, null, 4)}</pre>
输出将是
