Angular Treeview
|
|
================
|
|
|
|
Pure [AngularJS](https://www.angularjs.org) based tree menu directive.
|
|
|
|
[](https://jsfiddle.net/eu81273/8LWUc/)
|
|
|
|
## Installation
|
|
|
|
Copy the script and css into your project and add a script and link tag to your page.
|
|
|
|
```html
|
|
<script type="text/javascript" src="/angular.treeview.js"></script>
|
|
<link rel="stylesheet" type="text/css" href="css/angular.treeview.css">
|
|
```
|
|
|
|
Add a dependency to your application module.
|
|
|
|
```javascript
|
|
angular.module('myApp', ['angularTreeview']);
|
|
```
|
|
|
|
Add a tree to your application. See [Usage](#usage).
|
|
|
|
## Usage
|
|
|
|
Attributes of angular treeview are below.
|
|
|
|
- angular-treeview: the treeview directive.
|
|
- tree-id : each tree's unique id.
|
|
- tree-model : the tree model on $scope.
|
|
- node-id : each node's id.
|
|
- node-label : each node's label.
|
|
- node-children: each node's children.
|
|
|
|
Here is a simple example.
|
|
|
|
|
|
```html
|
|
<div
|
|
data-angular-treeview="true"
|
|
data-tree-id="abc"
|
|
data-tree-model="treedata"
|
|
data-node-id="id"
|
|
data-node-label="label"
|
|
data-node-children="children" >
|
|
</div>
|
|
```
|
|
|
|
Example model:
|
|
|
|
```javascript
|
|
$scope.treedata =
|
|
[
|
|
{ "label" : "User", "id" : "role1", "children" : [
|
|
{ "label" : "subUser1", "id" : "role11", "children" : [] },
|
|
{ "label" : "subUser2", "id" : "role12", "children" : [
|
|
{ "label" : "subUser2-1", "id" : "role121", "children" : [
|
|
{ "label" : "subUser2-1-1", "id" : "role1211", "children" : [] },
|
|
{ "label" : "subUser2-1-2", "id" : "role1212", "children" : [] }
|
|
]}
|
|
]}
|
|
]},
|
|
{ "label" : "Admin", "id" : "role2", "children" : [] },
|
|
{ "label" : "Guest", "id" : "role3", "children" : [] }
|
|
];
|
|
```
|
|
|
|
## Selection
|
|
|
|
If tree node is selected, then that selected tree node is saved to $scope."TREE ID".currentNode. By using $watch, the controller can recognize the tree selection.
|
|
|
|
|
|
```javascript
|
|
$scope.$watch( 'abc.currentNode', function( newObj, oldObj ) {
|
|
if( $scope.abc && angular.isObject($scope.abc.currentNode) ) {
|
|
console.log( 'Node Selected!!' );
|
|
console.log( $scope.abc.currentNode );
|
|
}
|
|
}, false);
|
|
```
|
|
|
