按钮的判断

var record = ajaxgrid.getAllRecords();

    if(record.length>0){

    	var isPack=record[0].get("dispatchDate");

    	if(isPack==null){

    		onsave_id.display("block");

    		dispatch_id.display("block");

    		dispatchMan_id.display("none");

    		ajaxgrid.setColumnReadonly("rfidCode",false);

    	}else{

    		onsave_id.display("none");

    		dispatch_id.display("none");

    		dispatchMan_id.display("block")

    		ajaxgrid.setColumnReadonly("rfidCode",true);

    	}

    }else{

    	onsave_id.display("none");

		dispatch_id.display("none");

		dispatchMan_id.display("none");

		ajaxgrid.setColumnReadonly("rfidCode",true);

    }

}

获取当前时间：CommonUtil.getDateTime()

//时间过滤

String opTime1 = this.getProperty("opTime1");//开始时间

String opTime2 = this.getProperty("opTime2");//结束时间

if(opTime1!=null&&!"".equals(opTime1)){

			  params.addParam("fillDate",Timestamp.valueOf(opTime1),QueryParam.RELATION_GE);

		 }

	     if(opTime2!=null&&!"".equals(opTime2)){

		    Timestamp endDate = CommonUtil.addDay(Timestamp.valueOf(opTime2), 1);//结束时间默认加一天

		    params.addParam("fillDate",endDate,QueryParam.RELATION_LE);

	     }
