passing javascript variable into embedded survey form

Question

I've looked around a lot but can't seem to find the best way to go about this. How can I input the variable values (p1, p2, p3) into the URL at the bottom of this code?

I'm taking variables that are formatted with "+"'s as spaces, formatting them to have "%20" as spaces; then, passing them into the link at the bottom of this code used for this embedded typeform.

<script type="text/javascript">// <![CDATA[
function getParameterByName (name, url) {
  if (!url) url = window.location.href;
  name = name.replace(/[\[\]]/g, "\\$&");
  var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
  results = regex.exec(url);
  if (!results) return null;
  if (!results[2]) return '';
  return decodeURIComponent(results[2].replace(/\+/g, " "));
}

var p1 = getParameterByName('p1')
var p2 = getParameterByName('p2')
var p3 = getParameterByName('p3')

p1 = p1.replace(/\+/g, "%20");
p2 = p2.replace(/\+/g, "%20");
p3 = p3.replace(/\+/g, "%20");
// ]]></script><script type="text/javascript">// <![CDATA[

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

var p1 = getParameterByName('p1')
var p2 = getParameterByName('p2')
var p3 = getParameterByName('p3')

p1 = p1.replace(/\+/g, "%20");
p2 = p2.replace(/\+/g, "%20");
p3 = p3.replace(/\+/g, "%20");
// ]]></script>

Your getParameterByName function requires two arguments but is only given one. You should pass in the data-url property of the div by using .dataset.url .

 function getParameterByName(name, url) { if (!url) url = window.location.href; name = name.replace(/[\\[\\]]/g, "\\\\$&"); var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"), results = regex.exec(url); if (!results) return null; if (!results[2]) return ''; console.log('The value of ' + name + ' is: ' + results[2].replace(/\\+/g, " ")); return decodeURIComponent(results[2].replace(/\\+/g, " ")); } var p1 = getParameterByName('p1', document.getElementsByClassName('typeform-widget')[0].dataset.url) var p2 = getParameterByName('p2',document.getElementsByClassName('typeform-widget')[0].dataset.url) var p3 = getParameterByName('p3', document.getElementsByClassName('typeform-widget')[0].dataset.url) p1 = p1.replace(/\\+/g, "%20"); p2 = p2.replace(/\\+/g, "%20"); p3 = p3.replace(/\\+/g, "%20"); 

 <!-- Change the width and height values to suit you best --> <div class="typeform-widget" data-url="https://eatforklore.typeform.com/to/XPDPsx?p1=p1valuehere&amp;p2=p2valuehere&amp;p3=p3valuehere&amp;p4=xxxxx" data-text="Mo. 1 Product Reviews" style="width:100%;height:500px;"></div>
