5. Use case demo

Before we jump into the tutorial let's try to understand what is ServiceNow getReference function

• GlideForm - getReference(String fieldName, Function callBack)
  Returns the GlideRecord for a specified field.
• If a callback function is present, this routine runs asynchronously. The browser (and script) processing continues normally until the server returns the reference value, at which time, the callback function is invoked. If a callback function is not present, this routine runs synchronously and processing halts (causing the browser to appear to hang) while waiting on the server response.
• Important: It is strongly recommended that you use a callback function.
• Callback function support for ServiceCatalogForm.getReference is available.
