JSON.stringify output para div de maneira bem impressa

163

I JSON.stringifyum objeto json por

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

O 2argumento acima deve imprimir o resultado. Faz isso se eu fizer algo parecido alert(result). No entanto, quero enviar isso para o usuário anexando-o dentro de uma div. Quando faço isso, recebo apenas uma única linha aparecendo. (Não acho que esteja funcionando porque as quebras e os espaços não estão sendo interpretados como html?)

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

Existe uma maneira de produzir o resultado de JSON.stringifypara uma div de uma maneira bonita de impressão?

Use um elemento pré? Usar uma biblioteca de pré-identificação?

Por favor use uma <pre> tag

demo: 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>

a fim de evitar longas filas para sair do contêiner do qual a tag pré é filha, deve-se adicionar as seguintes regras de css à tag pré: stackoverflow.com/a/248013/883083

@ user3692823: Obrigado. Eu atualizei. Esta resposta foi escrita em 2013 e innerHTMLera mais comum na época. textContenttornou-se uma propriedade padrão mais tarde.

Verifique se a saída JSON está em uma <pre>tag.

A divulgação completa Eu sou o autor deste pacote, mas outra maneira de saída JSON ou objetos JavaScript em uma completa forma legível com sendo partes pular capazes, recolhê-los, etc. é nodedump, https://github.com/ragamufin/nodedump

Minha proposta é baseada em:

  • substitua cada '\ n' (nova linha) por um <br>
  • substitua cada espaço com o & nbsp;

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>

Se sua <pre>tag estiver mostrando uma única linha de JSON, porque é assim que a string já é fornecida (por meio de uma API ou de uma função / página fora de seu controle), você pode reformatá-la da seguinte maneira:

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);
    })();

ou jQuery:

    $(formatJson);

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

Se isso é realmente para um usuário, melhor do que apenas produzir texto, você pode usar uma biblioteca como esta https://github.com/padolsey/prettyprint.js para produzi-la como uma tabela HTML.

Considere os retornos da API REST: 

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

Em seguida, você pode fazer o seguinte para imprimi-lo em um bom formato:

<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);

use style, white-space: prea <pre>tag também modifica o formato do texto que pode ser indesejável.

imprime o estado de um componente com JSX

render() {
  return (
    <div>
      <h1>Adopt Me!</h1>
      <pre>
        <code>{JSON.stringify(this.state, null, 4)}</code>
      </pre>
    </div>
  );
}

para quem quiser mostrar json dobrável pode usar renderjson

Aqui está o exemplo, incorporando o render js javascript em html

        // 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")
