今天你终于完成了头大了三天的treeView需求

完整的官方demo路径如下doc>backend_template>products-WBOB30DGR>html>treeview.html,需要的依赖都在asstes目录中,同时还包含一些其他的样式和功能
把其他无关的功能去掉,现在就只剩下一个主要标签

<ul id="tree1"></ul>

这个标签是树的主体,传入的数据会直接渲染到li标签中。
然后是初始化方法

<script type="text/javascript">
			jQuery(function($){
	var sampleData = initiateDemoData();//see below


	$('#tree1').ace_tree({
		dataSource: sampleData['dataSource1'],
		multiSelect: true,
		cacheItems: true,
		'open-icon' : 'ace-icon tree-minus',
		'close-icon' : 'ace-icon tree-plus',
		'selectable' : true,
		'selected-icon' : 'ace-icon fa fa-check',
		'unselected-icon' : 'ace-icon fa fa-times',
		loadingHTML : '<div class="tree-loading"><i class="ace-icon fa fa-refresh fa-spin blue"></i></div>'
	});
	
	$('#tree2').ace_tree({
		dataSource: sampleData['dataSource2'] ,
		loadingHTML:'<div class="tree-loading"><i class="ace-icon fa fa-refresh fa-spin blue"></i></div>',
		'open-icon' : 'ace-icon fa fa-folder-open',
		'close-icon' : 'ace-icon fa fa-folder',
		'selectable' : false,
		multiSelect: false,
		'selected-icon' : null,
		'unselected-icon' : null
	});
	
	/**

	.on('loaded.fu.tree', function(e) {

initiateDemoData()这个方法名误导了我好久,根据字面意思是初始化整个tree的意思,后来发现,如果在里面打印参数的话,不仅初始化会调用,在每次点击父标签生成子列表的时候也会调用,这说明这个函数的功能是给生成的列表提供数据,无论是初始化还是渲染下一级。

var tree_data = {
			'for-sale' : {text: 'For Sale', type: 'folder'}	,
			'vehicles' : {text: 'Vehicles', type: 'folder'}	,
			'rentals' : {text: 'Rentals', type: 'folder'}	,
			'real-estate' : {text: 'Real Estate', type: 'folder'}	,
			'pets' : {text: 'Pets', type: 'folder'}	,
			'tickets' : {text: 'Tickets', type: 'item'}	,
			'services' : {text: 'Services', type: 'item'}	,
			'personals' : {text: 'Personals', type: 'item'}
		}

首先声明数据源tree_data,从声明可以看出,数据源的格式是其中必须包含有text和type两个参数,text是展示的值,type有两种值,item表示下面没有children,标签左边有checkbox,可以被选择。folder表示有children,标签带加号,可以展开,无论是否真的有children。

tree_data['for-sale']['additionalParameters'] = {
			'children' : {
				'appliances' : {text: 'Appliances', type: 'item'},
				'arts-crafts' : {text: 'Arts & Crafts', type: 'item'},
				'clothing' : {text: 'Clothing', type: 'item'},
				'computers' : {text: 'Computers', type: 'item'},
				'jewelry' : {text: 'Jewelry', type: 'item'},
				'office-business' : {text: 'Office & Business', type: 'item'},
				'sports-fitness' : {text: 'Sports & Fitness', type: 'item'}
			}
		}

tree_data中如果有children的话需要定义在additionalParameters中

var dataSource1 = function(options, callback){
			var $data = null
			if(!("text" in options) && !("type" in options)){
				$data = tree_data;//the root tree
				callback({ data: $data });
				return;
			}
			else if("type" in options && options.type == "folder") {
				if("additionalParameters" in options && "children" in options.additionalParameters)
					$data = options.additionalParameters.children || {};
				else $data = {}//no data
			}
			
			if($data != null)//this setTimeout is only for mimicking some random delay
				setTimeout(function(){callback({ data: $data });} , parseInt(Math.random() * 500) + 200);

			//we have used static data here
			//but you can retrieve your data dynamically from a server using ajax call
			//checkout examples/treeview.html and examples/treeview.js for more info
		}

然后声明var dataSource1 = function(options, callback){ ,其中options保存着父标签的数据。
这里可以进行数据的动态加载
简化一下结构就是

var dataSource1 = function(options, callback){
      var $data = ...   //进行数据的加载
      callback({ data: $data });
}

最后返回dataSource1.

  1. 下面是初始化过程
var sampleData = initiateDemoData();//see below

$('#tree1').ace_tree({
		dataSource: sampleData['dataSource1'],//数据源
		multiSelect: true,//是否允许多选
		cacheItems: true,//缓存是否有效
		'open-icon' : 'ace-icon tree-minus',//标签打开的icon
		'close-icon' : 'ace-icon tree-plus',//标签关闭的icon
		'selectable' : true,//checkBox是否有效
		'selected-icon' : 'ace-icon fa fa-check',//选中状态的icon
		'unselected-icon' : 'ace-icon fa fa-times',//未选中状态的icon
		loadingHTML : '<div class="tree-loading"><i class="ace-icon fa fa-refresh fa-spin blue"></i></div>'//加载icon
	});

一些时间的回调函数

/**
	//please refer to docs for more info
	$('#tree1')
	.on('loaded.fu.tree', function(e) {
	})
	.on('updated.fu.tree', function(e, result) {
	})
	.on('selected.fu.tree', function(e) {
	})
	.on('deselected.fu.tree', function(e) {
	})
	.on('opened.fu.tree', function(e) {
	})
	.on('closed.fu.tree', function(e) {
	});
	*/

使用时直接加在后面

$('#tree2').ace_tree({
		dataSource: sampleData['dataSource2'] ,
		loadingHTML:'<div class="tree-loading"><i class="ace-icon fa fa-refresh fa-spin blue"></i></div>',
		'open-icon' : 'ace-icon fa fa-folder-open',
		'close-icon' : 'ace-icon fa fa-folder',
		'selectable' : false,
		multiSelect: false,
		'selected-icon' : null,
		'unselected-icon' : null
	}).on('loaded.fu.tree', function(e) {
	});

,function中的参数有两种情况,一个参数时保存的我也不知道是个啥,,,两个参数时}).on('loaded.fu.tree', function(e,data) { 其中data保存的是触发事件的标签的数据。

大致就是这样
