undefined error

[aryajur]

I have a Javascript file (.js) and when I try to run it by double clicking it I get an error that 'navigator' is undefined. Error Code is 800A1391. The initial lines of code for the file is:


var agent = navigator.userAgent.toLowerCase();
if (agent.indexOf("konqueror")!=-1) agent = "konqueror";
else if (agent.indexOf("safari")!=-1) agent = "safari";
else if (agent.indexOf("opera")!=-1) agent = "opera";
else if (agent.indexOf("firefox")!=-1) agent = "firefox";
else if (agent.indexOf("msie")!=-1) agent = "msie";

window.onerror=handleErr;

How to I run it or debug this?

Standalone js is not hosted by any "browser". It is hosted by windows script host. Hence, navigotor object is not defined. You can only run through a browser. If you want to check your "double-click" default browser, you wrap it in a html page, say "anyname.htm".

<script>
var agent = navigator.userAgent.toLowerCase();
if (agent.indexOf("konqueror")!=-1) agent = "konqueror";
else if (agent.indexOf("safari")!=-1) agent = "safari";
else if (agent.indexOf("opera")!=-1) agent = "opera";
else if (agent.indexOf("firefox")!=-1) agent = "firefox";
else if (agent.indexOf("msie")!=-1) agent = "msie";

window.onerror=handleErr;
//etc etc
</script>
