Field Validation

[Rick1]

Hello,

Farley new to developing in ServiceNow, but I am tasked with creating a numeric input field that can only contain a value that is a multiple of the number 8; example would be, 8, 16, 24, 32,40…….

I know this would be a UI action, but how can I code to validate the input?

Thanks in advance for your guidance.

Hi Rick,

You should validate this via OnChange Client Script. Please refer below code:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
	if (newValue % 8 != 0) { // If the value is not multiple of the number 8; 
		alert("PASS ALERT MESSAGE HERE");
		g_form.clearValue('PASS FIELD COLUMN NAME HERE');
    
}

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

Hi Rick,

1) You need to create the 'Onchange' client script, as below. in the field name below select your Field name.

Script : 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
if(newValue % 8 == 0){
return true;
}
else{
g_form.showErrorBox('u_integer','please add only multiple of 8',false);
return false;
}

}

Please Mark it correct/helpful, if it helps you.

You can follow the below steps:-

Step 1:- Create an onChange client script for the field to validate it.

if (isLoading || newValue === '') {
return;
}

}

}
