Not able to get the response in client script from script include

mohanambalnanja · ‎03-26-2024

Hi All,

As per the requirement, I need to capture the "Operational Status" change information in Business Service table string field.

I am able to get the answer in script include, but when I try to take that response in Client script it is not working.

var OptnlStusInfo = ' ';

var ga = new GlideAjax('ReferenceDataUtilAsync'); //script include name

ga.addParam('sysparm_name', 'getBusinessServiceOperationStatusChoice'); //function in script include

ga.addParam('sysparm_operationalStatus', newValue);

ga.addParam('sysparm_loggedinuser',loggedInUsr);

ga.getXMLAnswer(StatusInfo);

function StatusInfo(response)

{

OptnlStusInfo = response;

//.responseXML.documentElement.getAttribute("OptnlStusInfo");

}

When I print the return result in script include it is giving expected result.

I am facing issue when I call that response in client script.

Please help me on this .

Thank you.

Hi @mohanambalnanja

When working with GlideAjax and Client Scripts in ServiceNow, it’s crucial to understand that the Ajax response is asynchronous. This means that the code execution does not wait for the response before moving on to the next line. The callback function (StatusInfo in your case) handles the response once it is received, but any code that relies on the response from the server must be inside this callback function or called from within it.

From your description, it seems like the issue may be related to how you’re attempting to use the OptnlStusInfo variable after setting it within the callback function. If you’re trying to use OptnlStusInfo outside the callback function right after the getXMLAnswer call, it will not work as expected because the value would not have been updated yet.

var ga = new GlideAjax('ReferenceDataUtilAsync'); 
ga.addParam('sysparm_name', 'getBusinessServiceOperationStatusChoice'); 
ga.addParam('sysparm_operationalStatus', newValue);
ga.addParam('sysparm_loggedinuser', loggedInUsr);
ga.getXMLAnswer(function(response) { // Directly using anonymous function for callback
    var OptnlStusInfo = response; // This value is now scoped to this function
    processResponseStatus(OptnlStusInfo); // Call another function to process or use this info
});

function processResponseStatus(statusInfo) {
    // Process the status info here or update the UI as needed
    console.log(statusInfo); // For demonstration, let’s just log it
}
