ActiveX objects do not exist in anything but Internet Explorer. If you're trying to use them for XMLHTTPRequests, use the XMLHTTPRequest() object instead, using feature detection.
ActiveX 对象不存在于 Internet Explorer 中。如果您尝试将它们用于 XMLHTTPRequests，请改用 XMLHTTPRequest() 对象，使用特征检测。
if ("ActiveXObject" in window) { /* Do ActiveX Stuff */ }
else { /* ActiveX doesnt exist, use something else */ }

Below code should work, It is working on IE6 & FF 3.6.12 atleast.
下面的代码应该可以工作，它至少在 IE6 和 FF 3.6.12 上工作。
if(typeof(window.ActiveXObject)=="undefined"){
alert("ActiveX Object not supported");
}else {
alert("ActiveX Object supported");
}
