Auto populate reference field based on other reference field

rickw1 · ‎08-19-2015

Hi there,

I'm figuring out the best way to do this..

In my form, I have 2 fields: caller and hospital.

Caller refers to the users table, Hospital refers to the company table.

My goal is: whenever I populate the caller field, the system needs to lookup the hospital of that caller and needs to auto-populate that.

Example: Customer X is part of Hospital X. Customer X is the caller so will be populated in the caller field. The system recognizes that Customer X is part of Hospital X so hospital will be Hospital X.

Hope you guys can help me out!

We got it working!

Client script:

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


     if (isLoading || newValue == '') { 


           return; 


     } 


     


     var ga = new GlideAjax('GetCustomerData'); 


   ga.addParam('sysparm_name','getFieldValue');


   ga.addParam('sysparm_field','u_reference_1');


   ga.addParam('sysparm_user_id', g_form.getValue('caller'));


       ga.getXML(DoSomething); 


         


       function DoSomething(response) { 


             var company = response.responseXML.documentElement.getAttribute("answer");


             g_form.setValue('company',company); 


       } 


}

Script include:

var GetCustomerData = Class.create(); 


GetCustomerData.prototype = Object.extendsObject(global.AbstractAjaxProcessor, { 


     getFieldValue: function() { 


               var user = new GlideRecord('x_medt2_ihs_customers'); 


               user.get(this.getParameter('sysparm_user_id')); 


               if(! user.sys_id){ 


                                 return false; 


               } 


         return user[this.getParameter('sysparm_field')]; 


     } 


});

Thanks everybody for the great help on this!

Still getting AbstractAjaxProcessor undefined, maybe missing global qualifier

Hi,

Did you created the Script include? It should be accessible from All application scopes.

Umm it seems like the client script cannot "see" the script include. Try to add also this line:

ga.setScope('x_medt2_ihs');

I think you need

type: "GetCustomerData" before your closing }

I do this with all my script includes.
