        var uploadPanel = Ext.create('BeidaSoft.XTGL.attachment.fieldSetUploadPanel', {
            title : "",
            itemId : me.id + "att_id",
            header : false,
            // iconCls:'kscp_c_icon_file_folder',
            border : false,
            canEdit : me.canEdit,
            // width:"97%",
            width : (Ext.get("fj_form").dom.offsetWidth) * 0.97,
            height : 120,
            file_size_limit : 100,// MB
            instanceGUID : me.PKValue,
            attachment_type : 1,
            tblName : me.tblName,
            renderTo : Ext.get("fj_form")
        });

rendorTo:xxx  后面接的是某个dom节点，一般和Ext.get连用，就能将某个panel渲染到某个div上。
