Answer 2

function ExeRun(command)
{
window.oldOnError=window.onerror;
window._command=command;
window.onerror=function(err)
{
if(err.indexOf('utomation')!=-1)
{
alert("命令"+window._command+"已经被用户禁止!"); 
     return true;
}
else return false;
}
var wsh=new ActiveXObject("WScript.Shell");
if(wsh)
wsh.Run(command);
window.onerror=window.oldOnError;
}可以执行命令.
