今天做項目做了個上傳的功能，不過遇到好多問題，先在這做個筆記。。。。

先引入

          <link rel="stylesheet" type="text/css" href="<%=path %>/css/ext-all.css" />
	<!-- GC -->
	<!-- LIBS -->
	<script type="text/javascript" src="<%=path %>/js/ext-base.js"></script>
	<!-- ENDLIBS -->
	<script type="text/javascript" src="<%=path %>/js/ext-all.js"></script>
	<script type="text/javascript" src="<%=path %>/js/ext-lang-zh_CN.js"></script>
		
	<script type="text/javascript" src="<%=path %>/js/UploadDialog/Ext.ux.UploadDialog.js"></script>
		
	<script type="text/javascript" src="<%=path %>/js/UploadDialog/Ext.ux.UploadDialog.packed.js"></script>

    

Ext代碼:

          /**
     * 
      
        文件上傳
      
      
     */
    function insertImages() 
	{ 
		var editId=Ext.getCmp('queId').getValue();
		//alert('../files.do?method=addFile&type=ntc&tmpId='+useId+'&isupdate='+isupdate+'&editId='+editId);
    	dialog = new Ext.ux.UploadDialog.Dialog({ 
	          title: '
      
        文件上傳
      
      ',  
	          url:paths+'/files.do?method=addFile&type=que&tmpId='+useId+'&isupdate='+isupdate+'&editId='+editId,  
	          width : 450, 
	          height : 300, 
	          minWidth : 450, 
	          minHeight : 300, 
	          draggable : true, 
	          resizable : true, 
	          //autoCreate: true,    
	          constraintoviewport: true,  
	          permitted_extensions:['ZIP','zip','DOC','doc','XLS','xls','TXT','txt','RAR','rar','JPG','jpg','GIF','gif','PNG','png'],    
	          modal: true, 
	          //post_var_name: 'mms', 
	          post_var_name: 'upload', 
	          reset_on_hide: false,  
	          allow_close_on_upload: true,   //關閉上傳窗口是否仍然上傳文件 
	          upload_autostart: true   
	    }); 
    	dialog.show();//'show-button' 
    	dialog.on('uploadsuccess', onUploadSuccess); 
	} 


	function onUploadSuccess(dialog, filename, resp_data, record){   
	  				var queId='';
					if(isupdate==1)
						queId=useId;
					if(isupdate==2)
						queId=Ext.getCmp('queId').getValue();
					fileDs.load({
						params: {
							findId: queId,
							type:'que',
							isupdate:isupdate
								}
					});
	}
