- Load json: click on "load" button and load a json-string to opened form
- Expand/collapse single nodes by click on label (recursively - by click with pressed
CTRL
/META
key) - Expand/collapse all tree nodes by click on "expand all" and "collapse all" buttons
- Mark/unmark node labels by click on label with pressed
ALT
key - Show JSONPath of node by click on label with pressed

A simple lightweight pure-javascript library for drawing tree of json-nodes from json-object.
You can get json-object from json-string by JSON.parse(str)
method.
Demo: http://summerstyle.github.io/jsonTreeViewer
The library includes only 2 files - libs/jsonTree/jsonTree.js
(18 KB)
and libs/jsonTree/jsonTree.css
(2 KB).
html:
<link href="libs/jsonTree/jsonTree.css" rel="stylesheet" />
<script src="libs/jsonTree/jsonTree.js"></script>
javascript:
// Get DOM-element for inserting json-tree
var wrapper = document.getElementById("wrapper");
// Get json-data by javascript-object
var data = {
"firstName": "Jonh",
"lastName": "Smith",
"phones": [
"123-45-67",
"987-65-43"
]
};
// or from a string by JSON.parse(str) method
var dataStr = '{ "firstName": "Jonh", "lastName": "Smith", "phones": ["123-45-67", "987-65-43"]}';
try {
var data = JSON.parse(dataStr);
} catch (e) {}
// Create json-tree
var tree = jsonTree.create(data, wrapper);
// Expand all (or selected) child nodes of root (optional)
tree.expand(function(node) {
return node.childNodes.length < 2 || node.label === 'phoneNumbers';
});
You can create many trees on one html-page.
