請問 javascript + MSCOMM32.OCX元件問題
想請問一下我想要利用html+javascript 製作一網頁
然後會用到MSCOMM32.OCX這元件
但目前javascript 似乎抓不到MSCOMM32.OCX
CommPort都開不起來 ，狀態都是undefined
請問一下有可能是哪邊出了問題嗎??
謝謝~~~~~~~~~~~~~~~~
擷取程式碼如下：
<html>
<head>
<title>JS串口操作</title>
<script type="text/javascript">
function OpenPort()
{
if(MSComm1.PortOpen==false)
{
MSComm1.PortOpen=true;
alert("開啟");
}
else if(MSComm1.PortOpen==true)
{
alert("已開啟");
}
else
{
alert("失敗");
}
}
function ClosePort(){
if (MSComm1.PortOpen)
{
MSComm1.PortOpen = false;
alert("closed")
}
else
{
alert("already close!");
}
}
</script>
</head>
