Info Message on UI Page?

[Daniel188]

Hoping this is a relatively simple question; I couldn't find it via a precursory search in communities.

On a UI Page, how do I display an info message? 

Use case:

User hits Submit button on UI page
Client Script calls GlideAJAX script include
GlideAJAX does some processing, returns a value
callback function looks like this:

ga.getXML(myCallBack);
function myCallBack(response) {
  var response = response.responseXML.documentElement.getAttribute("answer");
  if (response.blahblah)
	gs.addInfoMessage("Record " + response.blahblah + " inserted successfully."); // doesn't work (gs is undefined)
}

The obvious one is alert, but there are a couple other ones that seem to work OOTB in UI pages.

this.addErrorMessage()

Unfortunately there isn't a "this.addInfoMessage()"

However, I found another workaround. Just define the glideform library yourself, and you can call it from there!

var g = new GlideForm();
g.addInfoMessage()
