How to use GlideAjax?

[ayushaggarw]

I have a task - 
When a user selects a Caller on an Incident form, the system should fetch the caller's department from the server
and populate a custom field on the form without reloading the page. Design the solution using a client callable
Script Include and a client script.

Conditions / expectations:
• Do not hardcode department values in the client script.
• Use GlideAjax for communication.
• Handle the case where the user has no department.
Success criteria: A working client-side interaction where the department is fetched from the server and populated
correctly.

I created column in incident table and create client script and script include and select the user with department but it does not autofill in the incident table why anyone help me out of this?

Hello @ayushaggarw ,

You can below code :

client script :

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
   var ga=new GlideAjax('getDepartment');
   ga.addParam('sysparm_name','getUserData');
   ga.addParam('sysparm_user',newValue);
   ga.getXMLAnswer(function(res){
	g_form.setValue('short_description',res)
// here i set department value in short description , you can set in your custom field
   })

   //Type appropriate comment here, and begin script below
   
}

Script include :

var getDepartment = Class.create();
getDepartment.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getUserData: function() {
        var gr = new GlideRecord('sys_user');
		gs.log(this.getParameter('sysparm_user'))
        if (gr.get(this.getParameter('sysparm_user'))) {
            if (gr.department) {
                return gr.getDisplayValue("department").toString();
				
            }
			else{
				gs.addErrorMessage('No valid department exist')
			}

        }
    },
    type: 'getDepartment'
});

Hi @ayushaggarw 

Client Script

Table: Incident
Type: onChange
Field name: Caller
Script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

	if(isLoading) {
		return;
	}

	if(newValue === '') {
		g_form.clearValue('u_custom_department');
	}

	var gaPhone = new GlideAjax('getUserPropertiesAjax');
	gaPhone.addParam('sysparm_name', 'get_department');
	gaPhone.addParam('sysparm_user', newValue);
	gaPhone.getXMLAnswer(_handleResponse);

	function _handleResponse(response) {
		var answer = response;
		
		g_form.setValue('u_custom_department', answer);
	}

}

Script Include

Name: getUserPropertiesAjax
Client callable: true
Script:

var getUserPropertiesAjax = Class.create();
getUserPropertiesAjax.prototype = Object.extendsObject(AbstractAjaxProcessor, {
	
	get_department : function() {
		var grUser = new GlideRecord('sys_user');

		if(grUser.get(this.getParameter('sysparm_user'))) {
			return grUser.getValue('department');
		}
	},
	
    type: 'getUserPropertiesAjax'
	
});
