/** Created by: Alex Wendland (me@alexwendland.com), 2014-08-06
|
|
||||||
*
|
|
||||||
* angular-json-tree
|
|
||||||
*
|
|
||||||
* Directive for creating a tree-view out of a JS Object. Only loads
|
|
||||||
* sub-nodes on demand in order to improve performance of rendering large
|
|
||||||
* objects.
|
|
||||||
*
|
|
||||||
* Attributes:
|
|
||||||
* - object (Object, 2-way): JS object to build the tree from
|
|
||||||
* - start-expanded (Boolean, 1-way, ?=true): should the tree default to expanded
|
|
||||||
*
|
|
||||||
* Usage:
|
|
||||||
* // In the controller
|
|
||||||
* scope.someObject = {
|
|
||||||
* test: 'hello',
|
|
||||||
* array: [1,1,2,3,5,8]
|
|
||||||
* };
|
|
||||||
* // In the html
|
|
||||||
* <json-tree object="someObject"></json-tree>
|
|
||||||
*
|
|
||||||
* Dependencies:
|
|
||||||
* - utils (json-tree.js)
|
|
||||||
* - ajsRecursiveDirectiveHelper (json-tree.js)
|
|
||||||
*
|
|
||||||
* Test: json-tree-test.js
