If you mean Javascript errors, you should look in the Javascript console (or Error console in Firefox, Developer tools in IE).

I can give you just the idea.

You can do it from analysis of the value of the member .stack of the exception object:

C#

function ProcessExceptionInformation(message, stack) {
    // extract position information from stack
    // output or log the exception information as required
}

//...

<pre lang="JavaScript">try {
    //do something
} catch(e) {
    ProcessExceptionInformation(e.message, e.stack);
}
