Seeking help verifying SAP portal login in Adobe form using JavaScript, need alternative solutions

Question

When a button is clicked in my Adobe Interactive Form, I aim to verify user credentials for the SAP portal using JavaScript, but I'm not receiving the expected status back. Here's the code I'm using:

when button CLICK event in the adobe digital form

var cPortalUrl = "https://nspek.com:50001/irj/portal?j_user= <userid>&j_password=<password>";

var cStatus;

var pingportalstatus =
function PortalPing (cPortalUrl){
var xmlHttp = new XMLHttpRequest();

xmlHttp.onreadystatechange = function()

{

cStatus = xmlHttp.status;

};

xmlHttp.open("GET", cPortalUrl, false);
xmlHttp.send();

return xmlHttp.status;
};

Any advice on why cStatus isn't being populated would be appreciated.

Thanks.

Hi, I think the issue is that the xmlHttp.status property is not guaranteed to be populated synchronously in your code due to the asynchronous nature of XMLHttpRequest. It's populated asynchronously when the state of the XMLHttpRequest changes. You can learn more here about how this works: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/status. I would use FETCH instead of XHR due to performance reasons. It would be something like this:var cPortalUrl = "https://nspek.com:50001/irj/portal?j_user=&j_password=";function PortalPing(cPortalUrl, callback) { fetch(cPortalUrl) .then(function(response) { if (response.ok) { callback(response.status); } else { callback(response.status); } }) .catch(function(error) { console.error("Fetch error:", error); callback(null); // Pass null status to callback to indicate error });}// Example usagePortalPing(cPortalUrl, function(status) { if (status !== null) { console.log("Status:", status); } else { console.log("Error occurred during fetch."); }});Hope this helps.
