Is it possible to get a value from the URL and change it to another value in a hidden field?


Example campaign URL with a Unbounce form: www.mydomain.dk?source=345

The URL variable ‘source=345’ correspondence with an ID variable (ex. ‘Ef45RfghtTY67HFD’) in another system which I’m sending data to trough a webhook.


So when I recieve the varible ‘source=345’ from the URL in my Unbounce form I need it to change that value to ‘Ef45RfghtTY67HFD’ and place than value to a hidden field called ‘leadsource_id’ before it get send through the webhook.


Ex.

source=345 -> leadsource_id=Ef45RfghtTY67HFD

source=301 -> leadsource_id=Gb65Gf345Rfgt3Ed

source=22 -> leadsource_id=bHN54Defr456REF

…and so on.


Is that possible?


Thanks in advance

Found a solution:


Ex. page with Unbounce form: www.mydomain.com?source=516


<script type="text/javascript"> 

  

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 URLsource = getParameterByName('source');  



if(URLsource == 516)

{document.getElementById('source_id').setAttribute('value','f7ter36f-ef5c-4b25-84');}

else if(URLsource == 229)

{document.getElementById('source_id').setAttribute('value','80fweb38-dede-43de');}

else if(URLsource == 119)

{document.getElementById('source_id').setAttribute('value','1abd2rtg-51a2-45dd');}

else

{document.getElementById('source_id').setAttribute('value','empty');}

</script>
