====== How can I record email conversion to split test ? ======

===== Get Email from QueryString =====

Suppose you have url like this : **http://www.example.com/?email=abc@example.com**

<code java>
function getQueryStrings() { 
  var assoc  = {};
  var decode = function (s) { return decodeURIComponent(s.replace(/\+/g, " ")); };
  var queryString = location.search.substring(1); 
  var keyValues = queryString.split('&'); 

  for(var i in keyValues) { 
    var key = keyValues[i].split('=');
    if (key.length > 1) {
      assoc[decode(key[0])] = decode(key[1]);
    }
  } 

  return assoc; 
} 

var param= getQueryStrings();
var _email = param["email"]; 
</code>

Now, You can grab email from either queryString and send data to cbsplit CallBack **recordEmailConversion()**
JavaScript Function Call is promised based:

<code java>
recordEmailConversion(_email).then(function() {
      // continue to your next task
});
</code>

===== Incase you are using HTML <form> , you could do the follow, =====

**[1] Add onSubmit Event to the Form**

<code html>
<form onsubmit="return recordEmailConversion()" >
</form>
</code>

**[2] Code for the CallBack "recordEmailConversion"**


<code html>
<script>
    function emailConversion(){
      var _email = document.querySelector('#inf_field_Email').value;
      recordEmailConversion(_email).then(function() {
        // redirect to next page
        return true;
      });
      return true;
    }
</script>
</code>
