Need solution for a unique problem

Question

I am creating a pre-screener where we are receiving ids in a unique format e.g. vbd155727_hgdsjSGdsuyegwuahs , I want to know if its possible for me to trim vbd155727_ and just send hgdsjSGdsuyegwuahs into my client link at the time of final redirection under a specific variable.

Hey @KGParadigm, here's how I think I'd tackle this using a `split()`.    Qualtrics.SurveyEngine.addOnload(function()    {    // get data from an embedded data field names LinkID    var fullLinkID = "${e://Field/LinkID}";        // split the data based on your '_' formatted string and trim it    var myLinkID = fullLinkID.split("_")[1];        // overwrite your embedded data field with your new cleaned up string ID    Qualtrics.SurveyEngine.setEmbeddedData("LinkID",myLinkID);    });Then on your client link URL redirect you would append `${e://Field/LinkID}`

Hi @KGParadigm , I found this on a previous post and it may be what you are looking for. It allowed me to create an ED field that only contained a certain range of characters from a field.Replace "ResponseID with the field you want. Replace the "13" and "18" with the character ranges you want to send. Replace "PatientID" with the name of the new ED field you want. Hope this helps! `Qualtrics.SurveyEngine.addOnReady(function(){/*Place your JavaScript here to run when the page is fully displayed*/var str = "${e://Field/ResponseID}";var res = str.substr(13,18);Qualtrics.SurveyEngine.setEmbeddedData("PatientID", res);});`
