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

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.
- 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
