GlideAjax - Client Callable Script Include

[@LaurentKalemera]

Hi @TechWithPri, could you please explain the use of keyword 'this' on the "user" variable, line 5? I know 'this' method connects variables of an object in a function, but in this case I am failing to connect the dots on how 'this' comes into place in this case. Thank you

[@techwithpri]

Hey 👋 When a client callable script include is called from a client script or business rule, a new instance of the script include is created. The this keyword refers to that specific instance, allowing you to access its properties and methods.

Just a query. Why we should avoid reference function completely? Shall we use call back reference function ? That will not affect the performance. That is asynchronous too.

[@techwithpri]

Hey !! Yes its true that its asynchronous and also callback function is present but getReference returns the entire record back when doing lookups, on the other hand GlideAjax script only return the necessary information which you are looking for. So GlideAjax is always a best choice 😃😃

Hey Pritam, I followed the steps mentioned by you but it's not working. Here is my Client Script: function onChange(control, oldValue, newValue, isLoading, isTemplate) { if (isLoading || newValue === '') { return; } //Type appropriate comment here, and begin script below var callerVar=new GlideAjax('getEmail'); callerVar.addParam('sys_param_name','getEmail'); callerVar.addParam('sys_param_get_user_details',g_form.getValue()); callerVar.getXML(emailDetails); function emailDetails(response){ var emailId=response.responseXML.documentElement.getAttribute('answer'); g_form.setValue('u_email',emailId); } } Script Includes: var getEmail = Class.create(); getEmail.prototype = Object.extendsObject(AbstractAjaxProcessor, { getEmail: function() { var user = this.getParameter('sys_param_get_user_details'); // Added quotes around parameter name var gRecord = new GlideRecord('sys_user'); gRecord.addQuery('sys_id', user); gRecord.query(); if (gRecord.next()) { return gRecord.email; // to return the email field from the GlideRecord } return ''; // Return an empty string if no user is found } }); Could you please review, and help me out?

[@techwithpri]

Hey 👋 Sorry for the late reply 😔 Please check the - callerVar.addParam('sys_param_get_user_details',g_form.getValue()); You supposed to put the field name inside of g_form.getValue() 🤓
