Hi Team,

Is getXMLAnswer() synchronous or asynchronous and please help me with a use case for getXMLAnswer() for better understanding . 

Thanks,

Hello @Manal Aquil 

getXMLAnswer() function is used to asynchronously retrieve data from a server-side script in XML format and display it in the client-side interface, typically a form or UI page. Here's a breakdown of its common use cases:

1. Dynamic Population of Form Fields:

Imagine a form field that needs to display data based on user input in another field.

You can use getXMLAnswer() to call a script that retrieves the relevant data dynamically using the user's input and populates the target field with the XML response.

2. Conditional Visibility of UI Elements:

You might want to show or hide certain UI elements (e.g., sections, buttons) based on specific conditions.

A script can leverage getXMLAnswer() to fetch data and control the visibility of elements based on the response.

3. Customizing User Interface Elements:

In some scenarios, you might need to dynamically modify the content or behavior of UI elements.

getXMLAnswer() can be used to fetch data from a script that generates the necessary XML structure to customize the UI elements as needed.

If my answer solves your query kindly mark my answer as accepted and helpful.

Hi,

It is async (docs link). 

The main advantage is that you do not have to parse full GlideAjax response to access data - with getXML() you need to perform additional processing:

var answer = response.responseXML.documentElement.getAttribute("answer");

Newb here, so pardon my confusion if it's silly, but if I want to wait until this returns it's value before continuing on with the function that's using this GlideAjax call, wouldn't I need to wrap it in a Promise? 

EDIT: Like this...
