for those who want to show collapsible json can use renderjson
Here is the example by embedding the render js javascript in html

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讨论(0) -
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)); }讨论(0) -
you can try this repository : https://github.com/amelki/json-pretty-html

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> ); }stringify

Please use a
<pre>tagdemo : 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>讨论(0)
