主框架布局之：Tree

                        

参考示例：主框架布局之：Tree
   
          

一：创建界面布局

<!--Layout-->
<div id="layout1" class="mini-layout" style="width:100%;height:100%;">
    <div class="header" region="north" height="70" showSplit="false" showHeader="false">
    </div>
    <div title="south" region="south" showSplit="false" showHeader="false" height="30" >    
    </div>
    <div title="center" region="center" bodyStyle="overflow:hidden;">    
        <!--Splitter-->
        <div class="mini-splitter" style="width:100%;height:100%;" borderStyle="border:0;">
            <div size="180" maxSize="250" minSize="100" showCollapseButton="true">
                
            </div>
            <div showCollapseButton="false">
                
            </div>        
        </div>
    </div>
</div>    
其中，Layout实现上、中、下布局；Splitter实现左、右折叠布局。            


            

二：创建Tree

创建Tree控件，放入Splitter左侧区域，作为功能操作树。

<!--Tree-->
<ul id="tree1" class="mini-tree" url="../data/listTree.txt" style="width:100%;height:100%;" 
    showTreeIcon="true" textField="text" idField="id" resultAsTree="false"  
    onnodeselect="onNodeSelect">        
</ul>           

url从服务端返回JSON格式如下：

[
    {id: "base", text: "Base", expanded: false},    
    {id: "ajax", text: "Ajax", pid: "base"},
    {id: "json", text: "JSON", pid: "base"},
    {id: "date", text: "Date", pid: "base"},
    {id: "control", text: "Control", pid: "base"},
    ......
]

通过 "id" 和 "pid" 组成树形结构，在创Tree时注意设置 "idField" 、 "parentField" 和 "resultAsTree" 属性。

           

三：创建Tabs

创建Tabs控件，放入Splitter右侧区域，作为主操作区域。

<!--Tabs-->
<div id="mainTabs" class="mini-tabs bg-toolbar" activeIndex="0" style="width:100%;height:100%;"      
    bodyStyle="border:0;background:white;"      
>        
    <div title="首页" url="../../docs/api/overview.html" >        
    </div>
</div>

                     

四：监听处理"nodeselect"事件

function showTab(node) {
    var tabs = mini.get("mainTabs");            
    var id = "tab$" + node.id;
    var tab = tabs.getTab(id);
    if (!tab) {
        tab = {};
        tab.name = id;
        tab.title = node.text;
        tab.showCloseButton = true;
        tab.url = node.url;
        tabs.addTab(tab);
    }
    tabs.activeTab(tab);
}        

function onNodeSelect(e) {
    var node = e.node;
    var isLeaf = e.isLeaf;            

    if (isLeaf) {
        showTab(node);
    }
}
