I JSON.stringify a json object by
result = JSON.stringify(message, my_json, 2)
The 2 in 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?)
{ "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.stringify to a div in a pretty print way?
This question is related to
javascript
html
json
pretty-print
stringify
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
print the state of a component with JSX
render() {
return (
<div>
<h1>Adopt Me!</h1>
<pre>
<code>{JSON.stringify(this.state, null, 4)}</code>
</pre>
</div>
);
}
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.js to output it as an HTML table.
for those who want to show collapsible json can use renderjson
Here is the example by embedding the render js javascript in 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")
// .object.syntax ("{", "}")
// .array.syntax ("[", "]")

A lot of people create very strange responses to these questions that make alot more work than necessary.
The easiest way to do this consists of the following
In actual code, an example will be (combining all steps together):
var input = document.getElementById("input").value;
document.getElementById("output").value = JSON.stringify(JSON.parse(input),undefined,2);
output.value is going to be the area where you will want to display a beautified JSON.
My proposal is based on:
var x = { "data": { "x": "1", "y": "1", "url": "http://url.com" }, "event": "start", "show": 1, "id": 50 };_x000D_
_x000D_
_x000D_
document.querySelector('#newquote').innerHTML = JSON.stringify(x, null, 6)_x000D_
.replace(/\n( *)/g, function (match, p1) {_x000D_
return '<br>' + ' '.repeat(p1.length);_x000D_
});<div id="newquote"></div>Consider your REST API returns:
{"Intent":{"Command":"search","SubIntent":null}}
Then you can do the following to print it in a nice format:
<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);
Make sure the JSON output is in a <pre> tag.
use style white-space: pre the <pre> tag also modifies the text format which may be undesirable.
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:
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);
})();
or jQuery:
$(formatJson);
function formatJson() {
var element = $("#json");
var obj = JSON.parse(element.text());
element.html(JSON.stringify(obj, undefined, 2));
}
