JSON.stringify output to div in pretty print way

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

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));
    }

Please use a <pre> tag

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>
