This seems to come straight from the example on the comm docs. This function is not defined you are supposed to define it yourself. Here's an example definition from this other StackOverflow question.

function getClientIdFromUrl() {
    var url = window.location.href;
    var regex = new RegExp("[?&]clientId(=([^&#]*)|&|#|$)"),
        results = regex.exec(url);
    if (!results) return null;
    if (!results[2]) return '';
    return decodeURIComponent(results[2].replace(/\+/g, " "));
}

That being said this is fairly unusual in Google Analytics implementations. You haven't shared much about your use case, but if all you are trying to do is pass clientIds from one domain to the other I would instead take a look at the Linker plugin.
