我JSON.stringify一个json对象
result = JSON.stringify(message, my_json, 2)
上面参数中的2应该打印结果。如果我执行类似alert(result)的操作，它会执行此操作。但是，我想通过将其附加到div中来将其输出给用户。当我这样做时，我只会出现一行。 （我不认为它有效，因为中断和空格不被解释为html？）
{ "data": { "x": "1", "y": "1", "url": "http://url.com" }, "event": "start", "show": 1, "id": 50 }
有没有办法以漂亮的打印方式将JSON.stringify的结果输出到div？
答案 0 :(得分：323)
请使用<pre>代码
var data = {
"data": {
"x": "1",
"y": "1",
"url": "http://url.com"
},
"event": "start",
"show": 1,
"id": 50
}
document.getElementById("json").innerHTML = JSON.stringify(data, undefined, 2);<pre id="json"></pre>

确保JSON输出位于<pre>标记中。

完全公开我是此软件包的作者，但另一种以可读方式输出JSON或JavaScript对象的方法是能够跳过部分，折叠它们等等nodedump，https://github.com/ragamufin/nodedump < / p>

如果这对用户来说真的比输出文本好，那么可以使用像https://github.com/padolsey/prettyprint.js这样的库将其输出为HTML表格。

考虑您的REST API返回：
{"Intent":{"Command":"search","SubIntent":null}}
然后，您可以执行以下操作以良好的格式打印它：
<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);

使用样式white-space: pre <pre>标记也会修改可能不合需要的文字格式。
答案 6 :(得分：1)
我的提议基于：
var x = { "data": { "x": "1", "y": "1", "url": "http://url.com" }, "event": "start", "show": 1, "id": 50 };
document.querySelector('#newquote').innerHTML = JSON.stringify(x, null, 6)
.replace(/\n( *)/g, function (match, p1) {
return '<br>' + ' '.repeat(p1.length);
});<div id="newquote"></div>
答案 7 :(得分：1)
如果您的<pre>标签显示的是单行JSON，因为这是已经提供了字符串的方式（通过api或控件之外的某些函数/页面），则可以这样重新格式化： / p>
HTML：
<pre id="json">{"some":"JSON string"}</pre>
JavaScript：
(function() {
var element = document.getElementById("json");
var obj = JSON.parse(element.innerText);
element.innerHTML = JSON.stringify(obj, undefined, 2);
})();
或jQuery：
$(formatJson);
function formatJson() {
var element = $("#json");
var obj = JSON.parse(element.text());
element.html(JSON.stringify(obj, undefined, 2));
}

许多人对这些问题做出了非常奇怪的回答，使工作量大大超出了需要。
最简单的方法包括以下内容
在实际代码中，将是一个示例（将所有步骤组合在一起）：
var input = document.getElementById("input").value;
document.getElementById("output").value = JSON.stringify(JSON.parse(input),undefined,2);
output.value将是您要显示美化JSON的区域。

使用JSX打印组件的状态
render() {
return (
<div>
<h1>Adopt Me!</h1>
<pre>
<code>{JSON.stringify(this.state, null, 4)}</code>
</pre>
</div>
);
}

对于那些想要显示可折叠json的用户，可以使用renderjson
这里是通过在HTML中嵌入render js javascript的示例

// CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE.
// Usage
// -----
// The module exports one entry point, the `renderjson()` function. It takes in
// the JSON you want to render as a single argument and returns an HTML
// element.
//
// Options
// -------
// renderjson.set_icons("+", "-")
// This Allows you to override the disclosure icons.
//
// renderjson.set_show_to_level(level)
// Pass the number of levels to expand when rendering. The default is 0, which
// starts with everything collapsed. As a special case, if level is the string
// "all" then it will start with everything expanded.
//
// renderjson.set_max_string_length(length)
// Strings will be truncated and made expandable if they are longer than
// `length`. As a special case, if `length` is the string "none" then
// there will be no truncation. The default is "none".
//
// renderjson.set_sort_objects(sort_bool)
// Sort objects by key (default: false)
//
// Theming
// -------
// The HTML output uses a number of classes so that you can theme it the way
// you'd like:
// .disclosure ("⊕", "⊖")
// .syntax (",", ":", "{", "}", "[", "]")
// .string (includes quotes)
// .number
// .boolean
// .key (object key)
// .keyword ("null", "undefined")
// .object.syntax ("{", "}")
// .array.syntax ("[", "]")
