Validation on field with below combination

[Deepika Mishra]

I have a requirement to be implemented for a field. For which I need to implement onChange script with below validation:

Alphanumeric combination of 14 digits where the value should start with "A" and only "-" is allowed as special character.

Please help me in implementing this requirement.

So there I need help me in understanding

Hello @Deepika Mishra 

Please try below code segment

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
   var regex = /^A[A-Za-z0-9-]{13}$/;
   var name = g_form.getValue('u_name');
   if(regex.test(name) == false){
	g_form.showFieldMsg('u_name','String should start with A and must contain 14 digits, Hyper (-) only allowed','error');
   }
}

Please mark my answer helpful, if it helps you

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

var pattern = /^A[A-Za-z0-9]{12}-[A-Za-z0-9]$/;

if (!pattern.test(newValue)) {

g_form.showFieldMsg(control.name, "Value should start with 'A' and be 14 characters long (including '-')", "error");

g_form.setValue(control.name, '', '');
} else {

g_form.hideFieldMsg(control.name);
}
}
