Html JSON.stringify 以漂亮的打印方式输出到 div

JSON.stringify output to div in pretty print way

提问by Alexis

I JSON.stringifya json object by

我JSON.stringify是一个 json 对象

result = JSON.stringify(message, my_json, 2)

The 2in the argument above is supposed to pretty print the result. It does this if i do something like alert(result). However, I want to output this to the user by appending it inside a div. When I do this I get just a single line showing up. (I don't think it is working because the breaks and spaces are not being interpreted as html?)

在2上面的说法应该是相当打印结果。如果我做类似的事情，它会这样做alert(result)。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，我只显示一行。（我认为它不起作用，因为中断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 }

Is there a way to output the result of JSON.stringifyto a div in a pretty print way?

有没有办法以JSON.stringify漂亮的打印方式将结果输出到 div？

Please use a <pre>tag

请使用<pre>标签

demo : http://jsfiddle.net/K83cK/

演示：http: //jsfiddle.net/K83cK/

var data = {
  "data": {
    "x": "1",
    "y": "1",
    "url": "http://url.com"
  },
  "event": "start",
  "show": 1,
  "id": 50
}


document.getElementById("json").textContent = JSON.stringify(data, undefined, 2);

<pre id="json"></pre>

Make sure the JSON output is in a <pre>tag.

确保 JSON 输出在<pre>标签中。

Full disclosure I am the author of this package but another way to output JSON or JavaScript objects in a readable way complete with being able skip parts, collapse them, etc. is nodedump, https://github.com/ragamufin/nodedump

完全披露我是这个包的作者，但另一种以可读的方式输出 JSON 或 JavaScript 对象的方法是能够跳过部分，折叠它们等nodedump，https://github.com/ragamufin/nodedump

My proposal is based on:

我的建议基于：

• replace each '\n' (newline) with a <br>
• replace each space with &nbsp;

• 用 <br> 替换每个 '\n'（换行符）
• 用   替换每个空格

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>' + '&nbsp;'.repeat(p1.length);
     });

<div id="newquote"></div>

If your <pre>tag is showing a single-line of JSON because that's how the string is provided already (via an api or some function/page out of your control), you can reformat it like this:

如果您的<pre>标签显示单行 JSON，因为字符串已经提供（通过 api 或某些不受您控制的函数/页面），您可以像这样重新格式化它：

HTML:

HTML：

<pre id="json">{"some":"JSON string"}</pre>

JavaScript:

JavaScript：

    (function() {
        var element = document.getElementById("json");
        var obj = JSON.parse(element.innerText);
        element.innerHTML = JSON.stringify(obj, undefined, 2);
    })();

or jQuery:

或 jQuery：

    $(formatJson);

    function formatJson() {
        var element = $("#json");
        var obj = JSON.parse(element.text());
        element.html(JSON.stringify(obj, undefined, 2));
    }

Consider your REST API returns:

考虑您的 REST API 返回：

{"Intent":{"Command":"search","SubIntent":null}}

Then you can do the following to print it in a nice format:

然后您可以执行以下操作以漂亮的格式打印它：

<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);

If this is really for a user, better than just outputting text, you can use a library like this one https://github.com/padolsey/prettyprint.jsto output it as an HTML table.

如果这真的是为用户准备的，比仅仅输出文本更好，您可以使用这样的库https://github.com/padolsey/prettyprint.js将其输出为 HTML 表格。

回答by user7986267

use style white-space: prethe <pre>tag also modifies the text format which may be undesirable.

使用样式white-space: pre的<pre>标签也修改这可能是不可取的文本格式。

for those who want to show collapsible json can use renderjson

对于那些想要显示可折叠 json 的人可以使用renderjson

Here is the example by embedding the render js javascript in html

这是通过在 html 中嵌入渲染 js javascript 的示例

        // 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:
