How to capture a customer's IP Address

*Workaround for Webflow users

1. Create a custom field called IP and hide it in Memberstack
2. Create a text field in Webflow and insert the custom attribute: data-ms-member = ip
3. Insert the Javascript (JQUERY):

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script><script>function getIp(callback){    function response(s)    {        callback(window.userip);        s.onload = s.onerror = null;        document.body.removeChild(s);    }    function trigger()    {        window.userip = false;        var s = document.createElement("script");        s.async = true;        s.onload = function() {            response(s);        };        s.onerror = function() {            response(s);        };        s.src = "https://l2.io/ip.js?var=userip";        document.body.appendChild(s);    }    if (/^(interactive|complete)$/i.test(document.readyState)) {        trigger();    } else {             document.getElementById("First-name").addEventListener("focusout", trigger);		    }}getIp(function (ip) {  document.getElementById('IP').value = ip;  console.log(ip);});</script>
