We can call script include from client script using Glideajax:
Calling a script include from the business rule or from any server-side scripting it is very easy and straightforward syntax is there for that.

Whereas calling script include from the client script will be a little bit tricky, we need to use the GlideAjax approach to call script include.

Use case:
On selecting a user field we are trying to populate the user information on other fields.

To get the requirement done,
The first thing we need is a client script to trigger on change functionality and then we required a script include to pull the data related to that user record.

Step 1:
Create a client script by selecting type as onChange and selecting the field as the user

Add the following script to your client script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === ”) {
return;
}

var user = g_form.getValue(‘u_user’);

//Call script include
var ga = new GlideAjax(‘global.sampleUtils’); //Scriptinclude
ga.addParam(‘sysparm_name’, ‘getUserDetails’); //Method
ga.addParam(‘userId’,user); //Parameters
ga.getXMLAnswer(getResponse);

function getResponse(response){
console.log(response);
var res = JSON.parse(response);
console.log(res);
g_form.setValue(‘u_phone’,res.mobile_phone);
g_form.setValue(‘u_email’,res.email);
}

}

Step 2:
Create a script include and make it client callable (select the client callable checkbox)
Add the following script to your script include:

var sampleUtils = Class.create();
sampleUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

getUserDetails: function(){
gs.addInfoMessage(‘script include triggered’);

var userId = this.getParameter(‘userId’);
gs.addInfoMessage(‘user scr–‘+userId);
obj = {};

var grSysUser = new GlideRecord(‘sys_user’);
if (grSysUser.get(userId)) {
obj.mobile_phone = grSysUser.getValue(‘mobile_phone’);
obj.email = grSysUser.getValue(’email’);
}
gs.addInfoMessage(obj+JSON.stringify(obj));
return JSON.stringify(obj);
},

type: ‘sampleUtils’
});

That’s it, now as soon as you select a user your fields will auto-populate based on that.
