主框架布局之：Menu
         
            

  參考示例：主框架布局之：Menu

            

           

一：創建界面布局

<!--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實現上、中、下布局；Splitter實現左、右折疊布局。

            


           

二：創建Menu          

創建Menu控件，放入頂部區域，作為功能操作項。

<ul id="menu1" class="mini-menubar" style="width:100%;"
    url="../data/listTree.txt" onitemclick="onItemClick" 
    textField="text" idField="id" parentField="pid" >
</ul>

url從服務端返回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"},
    ......
]

通過 "id" 和 "pid" 組成樹形結構，在創Tree時注意設置 "idField" 、 "parentField" 屬性。

           

三：創建Tabs           

創建Tabs控件，放入Splitter右側區域，作為主操作區域。

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

                      

四：監聽處理"itemclick"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 onItemClick(e) {        
    var item = e.item;
    var isLeaf = e.isLeaf;
    if (isLeaf) {
        showTab(item);
    }            
}
