BS架构下在前端读写超高频UHF标签

BS架构管理系统，需要在前端录入或者操作超高频UHF标签，首先需要下载友我RFID读写器web插件，RFID读写器web插件不仅支持windows系统，也支持国产信创系统，如麒麟和统信，安装完成后，直接代码如下：

async function G2Inventory()
{
	
		let resultdata = await rfidreader.G2_Inventory(0);
		if(resultdata.Result>0)
		{
            document.getElementById("CardNo").value = resultdata.CardNo;	
		}
		else
		{
			document.getElementById("CardNo").value= GetErrStr(resultdata.Result);
		}	
}

async function ReadBlock()
{
	var StartPos;
	
	StartPos = document.getElementById("BlockIDRead").value; 

	rfidreader.KeyStringMode=1;
	rfidreader.KeyString="0";
	
	let resultdata = await rfidreader.G2_Read(3,StartPos,16, 0);
		if(resultdata.Result>0)
		{
			document.getElementById("CardNo").value = resultdata.CardNo;
			document.getElementById("DataRead").value = resultdata.strData;
		}
		else
		{
			alert("读取失败，错误：" + GetErrStr(resultdata.Result));	
		}
}

async function WriteBlock()
{
	var StartPos;

	var Data;
	
	StartPos = document.getElementById("BlockIDWrite").value; 

	Data =document.getElementById("DataWrite").value;
	rfidreader.KeyStringMode=1;
	rfidreader.KeyString="0";
	
	let resultdata = await rfidreader.G2_Write(3,StartPos,0,Data);
	if(resultdata.Result>0)
		{
			document.getElementById("CardNo").value = resultdata.CardNo;
			alert("写入成功");
		}
		else
		{
			alert("写入失败，错误：" + GetErrStr(resultdata.Result));	
		}	
}

这样基本的寻标签，读写标签功能就有了。
