javascript implements a method for running local programs in a Web page

This article illustrates the javascript implementation of running native programs on a web page. To share for your reference, the details are as follows:

<input onclick="exec('notepad.exe')" value=" perform noteppad.exe" type="button">
<input onclick="exec('cmd.exe')" value=" perform cmd.exe" type="button">
<script language="javascript">
function exec(command)
{
window.oldOnError = window.onerror;
window._command = command;
window.onerror = function (err)
  {
 if (err.indexOf('utomation') != -1)
 {
  alert(' The command ' + window._command + '  Has been banned by the user! ');
  return true;
 }
 Else
  return false;
};
//-----------//
var wsh = new ActiveXObject('WScript.Shell');
if (wsh) wsh.Run(command);
wsh = null;
window.onerror = window.oldOnError;
}
</script>
