頁面：

<div id="editproject-div-list"></div>

$('#editproject-div-list').window({
    	href:'pmp/project/projects-look.jsp',
        title: '檢視專案情況',  
        maximized:true,
		collapsible:false,
		minimizable:false, 
		maximizable:false,
        cache : false
    });

<div id="tt" class="easyui-tabs" > 
    	<div title="甘特圖" id="plusdiv">      
	    	<iframe name='leftframe' marginwidth=10 marginheight=10 frameborder="no" width='100%' scrolling='no' height=100% src='<%=path %>/pmp/project/Project.html'></iframe>
	    </div>     
	    <div title="任務" id="taskdiv">   
	         <iframe name='leftframe' marginwidth=10 marginheight=10 frameborder="no" width='100%' scrolling='no' height=100% src='<%=path %>/pmp/project/projects-taskList.jsp'></iframe>   
	    </div>   
	    <div title="成果" id="">   
	        <iframe name='leftframe' marginwidth=10 marginheight=10 frameborder="no" width='100%' scrolling='no' height=100% src='<%=path %>/pmp/project/projects-achievement.jsp'></iframe>   
	    </div>   
	    <div title="編輯專案資訊" id="">   
	        <iframe name='leftframe' marginwidth=10 marginheight=10 frameborder="no" width='100%' scrolling='no' height=100% src='<%=path %>/pmp/project/projects-edit.jsp'></iframe>   
	    </div>  
	</div>
 

cache : false也設定了，為什麼還是走快取呢。於是在js的href屬性中加上了一個時間戳：

//取得當前時間
function getTimeStamp()
{
    // 宣告變數。
    var d, s;
    // 建立 Date 物件。
    d = new Date();
    s = d.getFullYear() + "-";
    s += ("0"+(d.getMonth()+1)).slice(-2) + "-";
    s += ("0"+d.getDate()).slice(-2) + " ";
    s += ("0"+d.getHours()).slice(-2) + ":";
    s += ("0"+d.getMinutes()).slice(-2) + ":";
    s += ("0"+d.getSeconds()).slice(-2) + ".";
    s += ("00"+d.getMilliseconds()).slice(-3);
    return s;
}
 

但是這樣麼有效果，因為我的look頁面中還有iframe想讓哪個iframe不取快取就在iframe的src中加上時間戳：

<%=path %>/pmp/project/Project.html?date=<%=CommonDate.getDateTime() %>
