Multi line message on Service Portal

[ServiceNow Adm1]

Hi Experts,

I have a requirement where on a selection of a variable value on Service Portal, I should display a multi-line message which will have colored text in between and embedded URLs like we have for HTML pages.

It should be displayed only when a specific value is selected and the content will change based on different values. Example; 

Information

This is a test message, it can have anything

Appreciate if you could help further on how to achieve it with single widget where I can use same widget to display 10 different messages.

So in your variable's widget record, you can access the g_form API so it works like you would in a client script.  Inject $scope as a parameter in the Client Controller's function, and then add 

var g_form = $scope.page.g_form;

With that, you can check the values of the Category variable and set a $scope variable to be printed in your HTML.  See https://serviceportal.io/g_form-api-in-embedded-widgets/ for an example of using g_form in Client Controllers.

If you aren't familiar with how to pass $scope information to your HTML, I recommend reading some documentation from AngularJS: https://docs.angularjs.org/guide/scope

In the widget you can use event field.change event (This event is broadcasted when a field is updated on the form) to update the value in the widget.

Also use $scope.page.g_form.getValue to get the value of the field.

I creaed a sample code to achieve something similar.

Here primary_contact is my field name, You can replace it with your field name

Client Controller 

function($scope, $rootScope, $timeout)
{

var c = this;
var detail = '';

	$rootScope.$on("field.change",function(evt,parms)
	{
		if (parms.field.name == 'primary_contact')
			{
				
			detail = 'Primary contact Detail is ' + $scope.page.g_form.getValue('primary_contact');
				c.data.detail = detail;
				c.server.update();
			}
		
			});

			
		

	
}

Server Script :

(function() {
  /* populate the 'data' object */
  /* e.g., data.table = $sp.getValue('table'); */
	data.detail = input.detail;

})();


HTML:

<div>
<!-- your widget template -->
  <input type='text' ng-model="::c.data.detail"> 
</div>
