Not able to clear the field value which is readonly and dependent on reference field

[Sravani36]

Hi not able to clear the value of string field which is dependent on Reference field. on change of user name it's working, but if the reference field is empty it's not working.

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

   
    var caller = g_form.getReference('first_user_name', doAlert); 
    function doAlert(caller) {
    var a=    g_form.setValue('user_id',caller.user_name);
        //alert(a);
        var b = caller.user_name.split('@');
        //alert(b);
        g_form.setValue('selected_user_names',b[0]);
        

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

I need to clear the user id once the Reference field (first_user_name) is empty but the above script is not working.

Hello

Can you write your   g_form.clearValue('user_id'); line in below loop and remove from the last of the script

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

g_form.clearValue('user_id');
      return;
   }

Please try this and if it works mark my answer correct

Update your code as:

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading) {
      return;
   }

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

 var caller = g_form.getReference('first_user_name', doAlert); 
    function doAlert(caller) {
    var a=    g_form.setValue('user_id',caller.user_name);
        //alert(a);
        var b = caller.user_name.split('@');
        //alert(b);
        g_form.setValue('selected_user_names',b[0]);
}
}

Feel free to mark correct, If I answered your query.

Hi,

Move the below loop before the "var caller = g_form.getReference('first_user_name', doAlert); " line

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