1.列出要實現的樣式：

2.實現的代碼：

分三大部分：

1）：頁面主體部分：mian.vm

<html>
<head>
  <title>Ks UI</title>
  #parse("ui:include")
  <style>
      body{padding:0;margin:0}
  </style>
  <script>
      $(document).ready(function(){
        var tabs_content = $("#content");
        tabs_content.tabs({
            border:false,
            fit:true
        });
        
        //添加tab頁面
        function addTabs(tab){
            tabs_content.tabs("add",{
                title:tab.text,
                closable:true,
                content : '<iframe frameborder="0" scrolling="auto" width="100%" height="100%" src="${path}'+tab.url+'"></iframe>'
            });
        }
        
        $("#tree_menu").tree({
            onClick: function(node){
                console.log(node);
                if(!tabs_content.tabs('exists',node.text)){
                    if(node.url){
                        addTabs(node);
                    }
                }else{
                    tabs_content.tabs("select",node.text);
                }
            }
        });
        
        //添加歡迎頁面
        addTabs({
            text:'歡迎使用Ks UI',
            url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/welcome.vm'
        });
    });
  </script>
</head>
<body class="easyui-layout">
        <div data-options="region:'north'" style="height:70px"></div>
        <div data-options="region:'west',split:true" title="菜單" style="width:240px;">
            <ul class="easyui-tree" id="tree_menu" data-options="url:'$path/ui/resource/demo/data/tree.json',method:'get',animate:true"></ul>
        </div>
        <div data-options="region:'center'">
            <div  class="easyui-tabs" id="content" >
            </div>
        </div>
</body>
</html>

說明：這部分代碼負責完成效果頁面的整體框架和效果頁面center上面的tabs，重點看tabs是如何實現的（代碼<script>函數部分）

2）：center中豎着的tabs部分：

就是index.vm文件

<html>
<head>
  <title></title>
  #parse("ui:include")
  <script>
      $(document).ready(function(){
        $("#tt").tabs({
            tabPosition:'left',
            fit:true,
            onSelect:function(title,index){
                open(index);
                
            }
        });
        
        function open(index){
        
            var tab = $("#tt").tabs("getTab",index);
            //console.log(tab);
            //console.log(tab[0]);
            //不重復打開 
            if(tab.attr("opend")){
                return;            
            }
            var url = tab.panel("options").url;
            //var op=tab.panel("options");
            //console.log(op);
            if(url){
                $(tab[0]).html('<iframe frameborder="0" scrolling="auto" width="100%" height="100%" src="${path}'+url+'"></iframe>');
                tab.attr("opend",true);
            }
            
        }
        
        open(0);
        
    });
  </script>
</head>
<body>

<div id="tt" class="easyui-tabs">
   <div title="基本實現" style="padding:10px;" data-options="url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/base.vm'">
   </div>
   <div title="面板工具欄" style="padding:10px;" data-options="url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/mbgjl.vm'">
   </div>
   <div title="自定義工具欄" style="padding:10px;" data-options="url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/zdygjl.vm'">
   </div>
    <div title="面板頁腳" style="padding:10px;" data-options="url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/mbyj.vm'">
   </div>
   <div title="加載面板內容" style="padding:10px;" data-options="url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/jzmbnr.vm'">
   </div>
   <div title="面板嵌套" style="padding:10px;" data-options="url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/mbqt.vm'">
   </div>
   <div title="流式面板" style="padding:10px;" data-options="url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/lsmb.vm'">
   </div>
   <div title="API" style="padding:10px;" data-options="url:'/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/api.vm'">
   </div>
</div>
</body>
</html>

3）：豎着的tabs中的每個小窗口的示例文件：base.vm

<html>
<head>
  <title></title>
  #parse("ui:include")
</head>
<body>
    <h2>基本面板Basic Panel</h2>
    <p>面板是其他組件或元素的容器</p>
    <div style="margin:20px 0 10px 0;">
        <a href="#" class="easyui-linkbutton" onclick="javascript:$('#p').panel('open')">打開</a>
        <a href="#" class="easyui-linkbutton" onclick="javascript:$('#p').panel('close')">關閉</a>
    </div>
    <div id="p" class="easyui-panel" title="Basic Panel" style="width:700px;height:200px;padding:10px;">
        <p style="font-size:14px">jQuery EasyUI framework helps you build your web pages easily.</p>
        <ul>
            <li>easyui is a collection of user-interface plugin based on jQuery.</li>
            <li>easyui provides essential functionality for building modem, interactive, javascript applications.</li>
            <li>using easyui you don't need to write many javascript code, you usually defines user-interface by writing some HTML markup.</li>
            <li>complete framework for HTML5 web page.</li>
            <li>easyui save your time and scales while developing your products.</li>
            <li>easyui is very easy but powerful.</li>
        </ul>
    </div>
</body>
</html>

附上：mian.vm中用到的tree.json:

這篇博文的目的主要是學習，各個main.vm和index.vm中<script></script>間函數的寫法，如何能熟練正確的使用easyui各個模塊的屬性和方法：

其中通過chrome瀏覽器的console平台，借助console.log()方法，打印出index.vm文件中比較難理解的幾個變量值：onSelect:function(title,index)中的title和index分別是tabs中各個子窗口的標題和索引號，索引號從0開始；

var tab = $("#tt").tabs("getTab",index); 打印出這里的var tab變量是整個大的頁面；

console.log(tab[0]); 注意console輸出的這個tab[0]恰好是tabs中選中的子窗口頁面；

var url = tab.panel("options").url 中的url就是：/cn/com/ksplatform/ui/demo/main/views/fcomponents/panel/base.vm，也就是在index.vm中每個子窗口的地址；

easyui中tree模塊的屬性：

$("#tree_menu").tree({
onClick: function(node){
console.log(node);
if(!tabs_content.tabs('exists',node.text)){
if(node.url){
addTabs(node);
}
}else{
tabs_content.tabs("select",node.text);
}
}
});

這個函數中的node是什么呢？

這點可以看easyui中tree的api（當然也可以直接console輸出）：

每個節點都具備以下屬性：

id：節點ID，對加載遠程數據很重要。
text：顯示節點文本。
state：節點狀態，'open' 或 'closed'，默認：'open'。如果為'closed'的時候，將不自動展開該節點。
checked：表示該節點是否被選中。
attributes: 被添加到節點的自定義屬性。
children: 一個節點數組聲明了若干節點。

前端還是經驗的積累，所以多看api！！，多參加實踐！！
